High-yield planting techniques of seed squash and key points for pest control
How to plant seed zucchini? Today's seeded zucchini varieties are modern classic high-tech genetic breeding techniques, the latest hybrid high-resistance super-shelled seed melon varieties, small and large series of classics.
This variety is suitable for high-density cultivation of 2,500 acres of small acre, drought-resistant and disease-resistant, and does not prematurely decay when the melon is fully mature. It effectively promotes the fullness of melon seeds and the improvement of grain color. The fullness of melon seeds is super good, and the skin is thin and thick. It is the highest variety among the small and large zucchini seeds. The yield per mu has reached 400 kg. Even under the conditions of extensive cultivation techniques, the yield of about 300 kg can be obtained. In the Heilongjiang region, the average annual yield per mu is 300 kg. The total growth period is 90 days.
First, the soil conditions
Choose the high-quality loam or sandy loam soil with deep and fertile soil. In the first three years, the non-cucumber crops in the mouth are covered with gentle slopes, which avoids low-lying and easy-water accumulation.
Second, the whole land ridge fertilization
1000kg of high-quality decomposed farmyard manure, 10-20 kg of diammonium phosphate and 15 kg of potassium sulphate per 1000 m2 are evenly sprinkled on the surface, and 2-3 kg of boron fertilizer is added per 1000 m2 of viscous and sandy soil. Then the plough is deep, thin, and ridged. The ridge distance is 65-70cm, the ridge height is 10-15cm, and the ridge is planted in a single row. The flat ridge should be high, and the slope ridge should not be too high.
Third, sowing
Sowing in the northeast region around May 15th, with 5cm soil layer, the average temperature of 5°C above 5°C is suitable for sowing time, the sowing depth is generally 2-3cm, and the appropriate amount of phoxim granules in the hole before sowing is fully mixed with soil. Control underground pests. 2,400-3,300 seedlings were planted according to different varieties per 1000 m2. Sloping land, medium and low fertility plots can be moderately densely planted, and flat and high-fertilizer plots should be properly planted. Because zucchini is not resistant to high temperatures, early sowing can significantly increase yield, and late sowing yields will be significantly reduced. For this reason, it is especially important to plant seeds as early as possible without frost.
Fourth, field management
Before emergence, the appropriate herbicide should be used for sealing treatment.
When the two leaves are one heart and the seed melon is stable, the foliar fertilizer is sprayed once, which not only improves the nutritional status of the plant, but also improves the disease resistance of the plant, and has significant disease prevention and yield increasing effects. Spraying "enzolol" once in 10-12 leaves can control both the length and the powdery mildew. The first melon is often because the plant is small, the climate is not suitable, the amount of male flowers is insufficient, and it is easy to cause stiff fruit and the amount of seed is small. Therefore, it should be destroyed as soon as possible, and the fruit should be started from the second female flower. In order to increase the fruit setting rate and increase the number of single melon seeds, honeybee-assisted pollination is configured in accordance with 2-3 boxes per hectare. After the melon, 10 kg of potassium sulfate and 5 kg of urea were applied every 1000 square meters. Spray "enzolol" again to prevent powdery mildew.
V. Pest control
Aphids are the main pests, which are easy to induce viral diseases. When they occur, they use 800-1200 times liquid or other special effects pesticide sprays. In the middle and late period, attention should be paid to the prevention and control of powdery mildew. Both "enzolol" and "multi-sulfur" suspensions can be used, sprayed once every 10-15 days, and sprayed three times. In the later period, it is necessary to pay attention to the situation that the soil is contaminated with water, mainly through high ridge cultivation, reasonable drainage layout to avoid water accumulation in the field, and “Ridemereâ€, “Antivirus cockroach†and “DuPont†can be used when the disease occurs. "Lu" and other agents are aimed at the prevention and control of fruit spray. For details, please consult the local crop hospital.
Six, simmering melon seeds
After 60 days of melon, the melons are piled up and matured for 15-20 days. The post-ripening time is very important. Fully ripening can significantly increase the grain fullness and increase the yield. Choose to eat melon seeds in the continuous sunny weather, and then spread the air on the clean floor in time.
7. Risks suggest that late planting, excessive planting density, insufficient bee source, drought during flowering, rain, and lack of fertility can cause poor pollination and difficulty in holding melons, which affects yield and is brought to the attention of growers.
