Scientific management of anti-Western cucurbits

If the leaves of the plant are rich in green and rich, the flowering will not be the result. The water and fertilizer should be strictly controlled, and the larger clods should be pressed against the vine head to inhibit the plant from growing wild. If the plant is thin, the leaves are yellow and thin, the water and fertilizer must be increased, and the first female flower should be removed. To promote vegetative growth. Timely supplementation of boron fertilizer in the early flower buds of zucchini, spraying the fruit juice Zingling and boron fertilizer once every 10 days or so, can activate the plant ecological growth positive energy, broaden the plant conduit path, and enhance the plant water absorption and fertilizer absorption. Improve fruit yield and quality, reduce fruit drop rate, and reduce the incidence of cracked fruit, dead fruit and deformed fruit.

Control the temperature of the zucchini flowering period, the temperature in the shed during the day is controlled at about 26 °C, and at night is not lower than 15 °C.

Improve the light and cover the grass curtain in time to uncover the straw curtain, extend the light time as much as possible, and use the photosynthetic nutrient film fertilizer to help the plant absorb a lot of light fertilizer, light energy, light, compatible with conventional fertilizer and nutrient to supply plant growth and development. limit. One-year benefits for one application.

Prevent disease and control insects, timely control pests and diseases, strengthen ventilation, reduce humidity in the shed, regularly apply pesticides, remove fallen petals and old leaves of diseased leaves, use pesticides together with new high-fat membranes, and modify high-toxic pesticides for poisoning, poisoning Pesticides are low toxicity and low toxicity pesticides are slightly toxic. Control the volatile and volatile pesticides, prevent the rainwater from scouring, reduce the dosage per acre by half, and improve the control effect by multiple times. (Jiang Xin)
