Non-pollution Cultivation Techniques of Seed Pumpkin in Dry Land
Seed squash is also known as white melon seeds. Heilongjiang Province is one of the major producing areas in China. After many studies, successfully summed up the high-yield and high-efficiency production mode of seed pumpkin and corn ribbon planting, so that the number of pumpkins per squash reached 3 to 5, and 320 to 750 seeds of single melon were harvested. Melon seeds 120 ~ 180kg, per mu production value of 1200 ~ 1800 yuan, Qingyang City, Gansu Province, 35% protein seeds, 24% fat, carbohydrate 24.4%, has a high nutritional and food value. First, choose suitable varieties After many years of introduction of the product than the test, suitable for the local ribbon planting excellent white melon seed varieties are: large round of Inner Mongolia, iron melon 5, Pingliang large plate, gold shell and so on. Second, rotation down Former crops should be beans, potatoes, wheat and corn, and they should have a rotation of more than 3 years with the cucurbit crops. Choose flat or sunny slopes, fertile soil, deep plowed layer, and loose land. Third, pre-broadcast preparation 1, Shizujifei, soil preparation to do the application of organic fertilizer 3000 ~ 4000kg per mu, urea 10kg, calcium superphosphate 60kg, sulfuric acid outside 15kg, combined with a one-time application. It is cultivated in small sorghum, with a pod spacing of 50 cm, a width of 50 cm, a height of 10 cm, and a mulch with a cover width of 70 cm. 2, soil disinfection before doing ramming with 50% carbendazim WP 0.5kg, phoxim or trichlorfon 0.2kg, mixed with the right amount of soil, sprinkle in the sowing hole, prevention and control of soil pests and diseases. 3, soak germination with 50 ~ 60 °C hot water immersed in constant stirring, the water temperature dropped to below 30 °C, continue to soak for 8 to 10 hours, and then remove the bud. The soaked seed is wrapped in a wet towel and germinated at 28 to 30°C for 14 to 48 hours. After most of the seeds have germinated, they are sown in time. Fourth, appropriate sowing Corn is sown in early April and pumpkins are planted from mid-April to early May. If the soil moisture is not good, watering the plugs before sowing and then sowing. The corn was broken with live film. The pumpkins were seeded on the spot under the membrane and 2 seeds per hole. Fifth, reasonable close planting The ribbons were planted with three pods of squash and corn. The number of maize and squash were 2200 per acre, and the squash and corn were sown in 2 rows per row. The plant spacing was 25-30 cm. Six, field management 1. Seedlings, seedlings, and seedlings were observed in time for seedling emergence. The seedlings were found to be in short supply and immediately replanted to ensure seedlings and seedlings. 2, membrane rupture seedlings melon seedlings after breaking the membrane rupture of the air, to prevent heat damage, in mid-May after the late frost, the melon seedlings will be released outside the membrane, with soil sealed good sowing points. Two to three true leaves of the pumpkin and 3 to 4 leaves of the corn are selected to leave one seedling that grows and grows robustly. 3, timely cultivator timely cultivation and weeding throughout the cultivation period. 4. Artificially-assisted powdered white melon seeds belong to the same plants as the male and female plants. They depend on insects as vectors for pollination. Insects are less active on rainy days. Artificially assisted pollination is required. Every day from 6 to 9 am, the male flowers that are loosely powdered are opened on the same day. Remove the corolla and gently apply the pollen to the female style. A male flower can give 2 to 5 female flowers. Artificial pollination can increase the fruit setting rate by more than 20%, and it can increase the yield of seeds. VII. Pest Control Technology The diseases and pests of pumpkins mainly include: melon powdery mildew, spot disease, virus disease and aphids. Powdery mildew mostly occurs in the middle and later stages. It can be controlled by spraying 300 times of 12% Lithosulfide mixture. The spotting disease mostly occurs in the early stage. 70% thiophanate-methyl wettable powder 800 times or 75% chlorothalonil can be used. Clear WP 800 times solution for spray control: Virus disease mostly occurs in the middle and later stages, and it can be sprayed with 20% of the virus A WP 500 times or 50% of the bacterin solution 400 times; the locust can be used to fight lice. Wei spray control, can also be used yellow trap. Eight, timely harvest When 80% of the melons in the field reach maturity (orange and melon skin are thick and hard), the melons are harvested when they start to wither, and the melons are fully ripened in a sunny place at Yangyang for 20 days, and then the seeds are broken. If the naked kernel melon seed after ripening time should not be too long, so as not to germinate seeds in the fruit. Naked kernel melon seeds should not be allowed to ferment, to avoid the loss of seed green skin affect the quality. The harvested seeds are washed, dried and stored to prevent mildew.
