Pearl is a hybrid of Mesh melons cultivated by vegetables of the Jiangsu Academy of Agricultural Sciences. The whole growth period is about 120 days. The fruit has a round shape, light green flesh, resistance to powdery mildew, strong adaptability, moisture resistance and high temperature resistance, and the fruit sugar content is 15-17%.
The cultivation of strong seedlings is planted in the spring in mid-February and electric wire trays are used to grow seedlings.
Set 20-30 days before planting and planting films, 1500-2000 kg of organic fertilizer per acre, 40-50 kg of ternary compound fertilizer, and 30 cm deep. A 6-meter-wide greenhouse is made of 3 畦, 25-30 cm wide, 1 metre wide, and 70 cm wide. A plastic drip-irrigation hose is placed in the center of the cymbal to cover the mulch. From March 20 to April 5, the soil temperature was stable at 15°C. Plant spacing was 60 cm and spacing was 55 cm. Each row was 2 rows and about 1200 plants were planted per acre. Perforate the planting, then use the soil seal to set the planting hole, pouring enough water, and then use drip irrigation.
After planting, the plantation was managed and closed after the planting to increase the temperature of the shed. The shed was controlled at 25-30°C during the day and 15-17°C at night. When the outside temperature is lower than 15°C, open the vent for a long period of time. Hang vine cultivation. Single vine pruning, removal of the main branch below the 11th and the 15th above the side branch, 11-15 of the lateral vines reserved for pollination and melon use, pollination leaves 2 leaves topping. When the plants had 25 leaves, the growth point was removed. The pollination is conducted at 8-10 am, and the pollen is evenly spread on the stigma, and the date is listed. When the claws have an egg size, they choose to leave a melon shaped melon, leaving 1 melon per plant. At the same time, the pruning is done to prevent loss of nutrients and improve air and light transmission between the plants. The pollination period is not watered, the melon water is swelled in time after the melons are set, and the swollen melon fertilizer is applied. Swelling manure fertilizer uses quick-acting fertilizer, applying 30 yuan compound fertilizer per acre. Watering should be done a few times and irrigation should be stopped 15 days before harvesting.
Control pests (1) aphids. A 30-mesh insect net was installed in the vent, and yellow plates were trapped inside the shed to control the spraying of avermectin and imidacloprid. (2) Starscream. Controlled with a spray of acetylene. (3) Broom disease. Proper close planting, reducing the wound area during pruning, and keeping the wound dry; controlling irrigation after onset, and spraying or smearing the disease immediately, can use thiophanate-methyl and bacillus manganese zinc, smeared into a paste to smear the diseased part , 3 days painted once, a total of 2-3 coating, can also be applied to the pruning of the wound; severe chlorothalonil spraying control. (4) Downy mildew. The temperature and humidity in the shed were controlled, and metalaxyl and methomy zinc and other drug sprays were used in the initial stage of the disease. (5) Powdery mildew. Control with triadimefon.
