Nowadays, many farmers are planting zucchini seeds. As one of the common vegetables in life, the demand in the market is still quite high. Then, how can farmers manage high-yield zucchini when planting zucchini seeds?
1. First, when farmers are planting, they need to do real-time early broadcast: the optimal temperature for pollination of zucchini is 22-25 degrees, more than 32 degrees pollen dysplasia, early sowing can avoid high temperature period, which helps to increase pollination rate. Increase planting yield.
2. Secondly, it is necessary to achieve reasonable density: the density of planting according to different varieties is also different. Reasonable close planting can effectively increase yield and reduce pests and diseases. It is hoped that the varieties of seed industry will have “short vine growth and strong growthâ€. The characteristics of strong disease resistance and strong melon ability are recommended. The planting density is 2000-2600, which is good for less seedlings and more for seedlings. The rate of sitting on the land with good water and fertilizer conditions is obviously improved.
3. Rational fertilization and irrigation: Zucchini is a hi-fertilizer crop. Increasing the application of phosphorus and potassium fertilizer can increase the yield. It has been proved that the application of organic fertilizer can effectively increase the plant's resistance, improve the melon and increase the yield, and strengthen the expanded melon. The management of water and fertilizer can ensure the normal development of the grain and ensure the yield.
4, improve the pollination rate: the introduction of bee source during the flowering period can significantly increase the yield, choose to plant in a spacious and ventilated plot can also increase the pollination rate.
5, timely harvest
When the root melon grows to about 0.3 kg in time, the diseased melon and the deformed melon should be removed early, so that the second and third melons rapidly expand. In addition to early harvesting of roots, other melons should not exceed 500 grams in principle, otherwise it is easy to cause premature senescence of stems and shorten the period of melons.
6. Pest control
1. Common diseases include gray mold and powdery mildew.
Smoke method: smoked shed once every 7-10 days in winter, and can be used alternately with chlorothalonil or ketone.
Powdery mildew: In the initial stage of the disease, use 10% Shigao 1500 times liquid, or Amishida 1500 times liquid spray, 7-10 days once, continuous spraying 2-3 times.
Gray mold: Spray 50% procymidone 1500 times solution or 70% pyrimethanil 1500 times solution at the beginning of the disease, spray once every 7-10 days, continuously spray 2-3 times.
2. Common pests include aphids and white meal.
Physical control: Insect net plus yellow plate, all the air outlets are covered with insect nets. The yellow plate of 25cm×40cm is hung in the shed, 30-40 pieces per acre, hanging between the rows to trap the mites.
Drug control: 10% imidacloprid wettable powder 1000-1500 times solution, or 1.8% avermectin EC 2000 times solution spray.
The above is a small series for everyone to explain how to increase the yield of zucchini seeds, I believe we can help. More agricultural technology knowledge is in the Hui Nong School!
