When the reporter interviewed Gao Huai Village in Luocheng Street, in the shed of the farmer Su Xianzhong, Master Su was busy picking peppers. Speaking of the situation of this year's Caicao Pepper, Master Su was puzzled to consult with reporters: “You see, the third malformation that I have picked now is a lot of malformations. It was the cold weather that affected flower bud differentiation; now the weather is warm, My tree is still quite good. I wanted to keep a good batch of good-quality bell peppers. How many of these four kinds of pepper malformations can sit now?
"Currently, the deformed fruit on the plant is still caused by improper temperature in the greenhouse. During the blooming and fruit setting period of the pepper, the daytime temperature of the greenhouse is controlled at 25-28°C, and the night temperature is controlled at 13-15°C. Between the time, this is conducive to the normal flower bud differentiation, while properly widening the temperature difference can also improve the quality of flower bud differentiation, reduce the deformed fruit, increase the fine fruit." Reporter replied.
“The daytime temperature in these ceilings is about 30°C, sometimes higher than 35°C. When entering the shed in the morning, the temperature is about 15-18°C. Isn't the temperature at noon high?†asked Su Xianzhong.
“When the noon temperature is higher than 35°C, it will not only affect the normal flower bud differentiation, but also will not be conducive to pollen germination. Basically it will not be able to be fertilized normally and there will be phenomena of parthenocarpy and a stale fruit. Therefore, this high temperature should be avoided as much as possible. In addition, in order to ensure the normal development of flower bud differentiation and reduce the formation of malformed fruit, it is necessary to pay attention to the spraying of boron-containing foliar fertilizers before flowering, such as Borel.
In order to ensure the fine fruit exchanges with the vegetable farmer Su Suilei, the reporter asked: “How do you keep the current four-pronged peppers?â€
Master Su smiled and told reporters: "Now the price of the bell pepper is so low. We don't have much control over the bell peppers, and we don't conduct fruit thinning. There aren't a few fine fruits. It's selling dehydrated food!"
After reporters transferred several sheds, they found that, like Su, because vegetable prices were reduced, farmers managed to relax, and they took a few fruits to leave a few fruits. They did not sparse fruit, and there were not a few vegetable growers who kept the main branches and side branches at the same time. There is a problem of excessive fruit settling. Since the plants themselves are in the late growth stage, the nutrient supply capacity is reduced, so that it is difficult to meet the demand for nutrients in the fruit growth process. Not only is there more deformed fruit, even Zhou Zheng's fruit is too small to meet the demand. Fine fruit requirements. Therefore, although the early plant due to poor flower bud differentiation and other causes of the plant's more deformed fruit, but the farmers can fruit in the fruit after the timely fruit thinning, leaving Zhou Zheng's fruit, reduce the number of deformed fruit, the general results of each branch 2 - 3 can be, for better growing plants can be properly used side branch results.
Timely watering and fertilization, pay attention to nutritional supplements for how to manage fertilizer and water after the last bit of peppers, Cai Nong Su Shouquan told reporters most of the practices of farmers. “Each year through May, when the temperature rises, the evaporation rate of water evaporates obviously. Before the first half month or so, the water was poured. Now, it is necessary to pour water once every seven to eight days. The original price is high and the fertilizer is lean. Now the price is low, and it is not too big. Flushing."
However, how can we ensure the normal growth and development of fruits without bragging? The reporter suggested: "When plants reach the late growth stage, it is recommended to use balanced fertilizers before flowering and setting in order to regulate plant growth and fruit setting during flowering. In order to avoid prolonged planting and flowering, fruiting should be avoided as much as possible. And even if it is watered, it is not necessary to replenish it; when the fruit grows to the size of the walnut, it will soon enter the fruit expansion period, and it should be flushed with the swelling fruit fertilizer in time, mainly based on high-potassium fertilizers. The nutrient supply needed should be as lean as possible for every water, but the amount of one-time lean should not be too large to prevent the root from being damaged due to excessive fertilizer concentration.†“Every year I use fertilizer is also good, but there are many The fruit still has umbilical rot. This is a different story.†The vegetable farmer next asked. "In the case of high temperatures and droughts, it is very easy to cause the occurrence of umbilical rot. On the one hand, calcium deficiency affects the control of water in umbilical cells, and on the other hand, it is caused by water supply disorders. The early supply of soil moisture to the plants is always adequate. When the plant grows vigorously, it suddenly lacks water, and the water that was originally supplied to the fruit is taken by the leaves, causing the fruit to suddenly lose water in large amounts, causing tissue necrosis and the formation of umbilical rot. Therefore, to prevent the occurrence of umbilical rot, due to the weak root color of the pepper, pour When water is poured on a small ground, the soil in the shed is formed into a group and when it falls on the ground, it should be immediately watered.In addition to fertilizing calcium-containing fertilizer, pay attention to foliar spray of calcium fertilizer. For the fruit of the occurrence of umbilical rot, should be removed in time to prevent the infection of bacteria. "Reduce the intensity of light, to avoid the occurrence of sunburn disease." The last part of the pepper, the resulting parts are in the upper part of the plant, and the summer light is strong, The surface of the fruit is easily sunburned and becomes white or light brown, and the cortex is thinner. To prevent this scorching from happening, is there a good way to deal with it?†asked Master Su of the sidelines.
Hearing this problem, Su Shouquan said with a smile: "This is not difficult, I have two ways. One way is to leave the lateral branches properly. Since there are few upper leaves, we can leave some side branches to shade the fruits. Generally, the side branches stay. 2-3 leaves can start with, these leaves can also create nutrients; another way is to fall properly as soon as possible, because the fruit is in the upper part of the plant, and even higher than the wire, before settling fruit, we should fall as soon as possible, as long as The appropriate bungee can be, so that the result of the part down, you can prevent the occurrence of sunburn, but also to prevent the results of broken branches." "You can use the shade net! Shading cool it in summer is not a small role!" The reporter smiled Say. "This shading net can indeed shave and cool, but after covering the shading net, I feel bad, 'All things grow but rely on the sun', no light, this tree and fruit grows is not good!" Su Shouquan shook his head and said. "What you said is not bad. Insufficient light will seriously affect the photosynthesis of plants. The less nutrients the plants produce, the more the growth of plants and fruits will be affected. However, in the case of noon high temperature and strong light, in the roof It is still necessary to cover the shade net, but it must be noted that in order to prevent insufficient lighting in the shade, the shade net cannot be covered all day.General shade nets should be set before 10:00 and before 3 pm. In the weather, sunburn is most likely to occur, so after a sudden sunny day after rain, shade nets should be set up in time to prevent the occurrence of sunburn,†the reporter explained. "This shade net can't be covered all day! We cover most of the time after the whole day. The original problem is here!" Master Su said with a smile.
Pest control should not neglect the development of powdery mildew, virus disease and other diseases and whitefly, thrips and other insect pests. Therefore, in day-to-day management, it must be prevented and integrated in order to prevent the occurrence of such pests and diseases in order to increase the fruit quality. “When it comes to the diseases on the bell peppers, is this powdery mildew and downy mildew a disease?†asked Master Nong Su, hurriedly.
"Powdery mildew and downy mildew are not a disease. From the point of view of disease symptoms, powdery mildew can be seen in the early stages of the disease. The leaves are covered with yellowish brown spots on the front, the edges are not obvious, and there are chlorotic yellow mottles. Yellow, the last dry off, the white spots on the back of the leaves have white powder, powdery mildew easily occurs in the case of dry and damp, and downy mildew occurs on the back of the leaves, there are sparse white spots on the lesions. The thin layer of mildew, the leaves slightly rolled up, observed from the front of the blade, visible light green irregular lesions, and diseased leaves are mostly lower leaves, severe disease leaves off, generally occurs in the case of high humidity.Control these diseases, First of all to do a good job in environmental control, followed by spraying control, downy mildew, vegetable farmers can use 72.2% propamocarb hydrochloride 600 times mixed 25% metalaxyl control; powdery mildew, available kasugamycin mixed meth Bujin control."
"For virus diseases and insect pests, we must do a good job of prevention. In the summer, it can be sprayed once a day for about 10 days before it is sprayed with cinnamizine hydrochloride or linnanmycin. For insect pests, it should be timely pruned and brought out in time. Outside the shed, the insects should be set aside for destruction, and the air outlets should be provided with insect-proof nets to prevent insects from flying in through the air inlets and to remove infestation sites such as weeds outside the shed in time.Pests such as whiteflies and thrips can be hung in the shed and trapped in yellow traps. , It is also possible to use 25% buprofezin (Pentacloprid) EC 1000 times and 3% imidate EC for 1500 times spray control."
"Currently, the deformed fruit on the plant is still caused by improper temperature in the greenhouse. During the blooming and fruit setting period of the pepper, the daytime temperature of the greenhouse is controlled at 25-28°C, and the night temperature is controlled at 13-15°C.

Reporter replied.
