First, the variety selection The planting of zucchini in Jilin area can be selected for about 105 days of growth period. The plant grows robustly and has strong disease resistance. The number of single melon seeds is about 400, the weight of 1000 grains is about 185 grams, and the average yield per acre is 150-180 kg. Such as Zenon Ruifeng No. 9, No. 9 Nongfeng, Jinyu Baixue, etc. Second, land selection, soil preparation and fertilization The seed squash is drought-tolerant and snorkeling. It is suitable for ventilation and light transmission. It should be planted with high-quality loam or sandy soil block with flat land, good irrigation and drainage conditions, non-melon crops, no salt and alkali, no pests and diseases, and deep soil layers. When the soil is suitable for cultivating, the base fertilizer is applied to the ground, and 3000-5000 kg of high-quality rotted farmyard manure, 30 kg of diammonium phosphate and 15 kg of potassium sulphate compound fertilizer are applied per mu. Third, sowing According to the local climatic conditions, it is basically the same as the corn sowing period, sowing from late April to early May. The line spacing is 60 cm, the plant spacing is 40-45 cm, and 2470-2800 plants are planted per mu. When the soil moisture is insufficient, the water should be sown after the water is spotted in the hole. The seeding is 2-3 cm deep and gently suppressed after sowing. If the seeds are not coated, an appropriate amount of insecticide should be added to control underground pests. 10 days after sowing, the whole seedlings will be planted, and the seedlings, seedlings and seedlings will be checked in time to ensure a strong seedling at each hole. Fourth, field management 1. Pre-emergence closure: 80-100 ml (or 96% Jinduer 4 - 60 ml) per acre is sprayed evenly on the soil surface with 40-50 kg of water. Try not to use acetochlor, otherwise it will easily cause deformed seedlings. 2. Post-emergence weeding: Use 5% fine grass grass 40-50 ml (or 12.5% ​​grass cover 30-40 ml) per acre to spray weeds evenly with water 30-40 kg. 3. Seedling management: When the seedlings reach a diameter of 30 cm, the fertilizers should be topdressed once, and 15 kg of urea and 10 kg of potassium sulphate compound fertilizer should be applied per acre. When 80% of the plants in the field are on average 1-2, and the length of the melon reaches 20 cm or more, the plot with insufficient base fertilizer is applied with 10-15 kg of urea per acre and is applied between large rows. 4. Auxiliary pollination: Calculate the flowering period according to the sowing date. Generally, it takes 7-10 days from sowing to emergence (landing live), 35-40 days from emergence to flowering, and bee source in 45-50 days after sowing. If the source of the bee is insufficient, manual assisted pollination should be performed. After entering the flowering period, artificial assisted pollination is performed every morning at 4-9. Pollination method: Take a male flower and remove the corolla. Put the pollen on the stamen on the pistil. Each male flower can wipe up to two female flowers. The pollination should be carried out on a sunny day. Fifth, timely harvesting and drying The post-ripening of the seeds with zucchini is very important. Generally, the melons begin to dry in the middle of August. At this time, do not immediately pick up the seeds, but should be piled in the ground, after 10-15 days, can increase production by one to two. Otherwise, not only the grain color is not good, dull, but the fullness will be greatly reduced, and the output will be significantly reduced. The seeding time should be mastered before the frost. If frost is encountered during drying, the frozen film will appear, which will affect the quality. The removed melon seeds are washed with water and placed on a concrete floor or on a mesh to dry. If there is no condition, you can use the fan cloth to dry. During the drying process, the seeds are flattened, and the tweezers are used to turn the sun. The skin can not be flipped before the skin is stretched. After the skin is stretched, the mold is turned over in time to avoid mildew. When the moisture of the seeds falls below 13%.
