2.1.1 Soil preparation
Requirements leveling, fine detailing. Need to deepen the land (40 cm), otherwise it is easy to form a plow layer.
2.1.2 Fertilization
The base fertilizer should use 5000--8000 kg organic fertilizer, and the amount should be large. In addition, 100 kg of compound fertilizer and 30 kg of superphosphate are added per acre. Organic fertilizer is planted in the greenhouse in double rows (size and size); Centimeter, small row 60 cm, spacing 40 cm, 1800--2000 per mu.
2.1.3 Soil Treatment
After turning to the ground, or after the completion of the work, the shed film is closed and the temperature is high for 10-15 days, which can play a good disinfection effect. Each mu with 50% carbendazim 1 kg, 50% phoxim 0.50--1 kg 45-60 kg of water, evenly sprayed on the surface of the organic fertilizer before recultivation, while spraying and turning the floor.
2.1.4 Colonization
When planting, the soil is required to be moist, and the depth of the hole is slightly deeper than that of the seedling hoe. It should be planted in shallow depth, and it is appropriate to cover the soil (just flush with the soil rake). Planting water after planting in time, the amount of water should not be too large, but must be thoroughly drenched.
2.1.5 Management after Planting
The temperature before the seedlings should be high, especially the ground temperature should be high; after the seedlings are slowly growing, the temperature should be slightly lower by about 3°C ​​before seedlings. This period is mainly to promote better development of the seedling roots (slightly higher ground temperature). The temperature during the result period was slightly higher after the seedling was more slowly. The method of “high-temperature fruit-keeping†should be adopted. The timing of air release should be determined according to the specific circumstances.
Air relative humidity 50% - 65%, soil moisture 65% - -85%, bogey water flood irrigation, ground water should be poured.
Watering, fertilizing. The results of early watering and fertilization should not be too much, too frequent, later re-application of phosphorus and potassium fertilizer, in order to facilitate coloring and promote fruit. Physiological diseases to be prevented in fertilizer and water management: stalk rot and umbilical rot.
The long-shelf tomato varieties of Zewin's large red fruit grow strongly, and they should adopt single stem pruning. After harvesting 6 ears, it can be exchanged for head treatment, which will help improve the yield and quality. Bao Hua Bao Guo: generally use 2.4-d or tomato Ling Hua spent treatment, in principle, should be open the same day, the bright yellow color of flowers, pay attention to strictly follow the instructions, the concentration can not be too high, or prone to injury .
2.2 Pest Control
2.2.1 Late blight. It is a highly epidemic disease. It is necessary to do field prevention, prevention, and investigation to prevent it in advance. Once it was discovered that spraying immediately, it was combined with air release. The commonly used drugs are Ruixin Mn-Zn, Kelu, Precise, anti-virus scorpion and so on.
2.2.2 Gray mold. Prevention and control should enhance ventilation and reduce temperature. The commonly used drugs are metalaxyl, quick-acting, and acetaminophen.
2.2.3 Leaf mould. To enhance ventilation and dehumidification, commonly used drugs include Dasheng, Garinong, and Jiatuo.
2.2.4 Whitefly. The main methods of prevention and control are closed greenhouses in winter, fumigation with ddv smoke or other insecticides; in addition, the combination of sprays of pesticides, commonly used once again net, moxibustion and so on.
Plant Extract has been classified to two types by extraction methods including the standard plant extract and ratio extract in china local market. If we want to distinguish between the two types ,we can see from the ingredients that we should pay attention to. The standard plant extract will be tested of its special ingredients that in the product maybe by HPLC, UV, TLC etc,but for the ratio extract,we don't pay attention to the special ingredients that in it or not,not to mention the purity of one ingredient.if you still confused about the cllasfication,pls contact us to know more.
