A number of measures to protect the results of zucchini in greenhouse

? In order to accelerate the growth of temperature plants, the temperature in the greenhouse should be properly increased, the temperature should be controlled at 25 ℃ ~ 28 ℃ in daytime and 15 ℃ ~ 18 ℃ at night, so as to promote plant growth and increase yield. As zucchini requires strong light, in practical operation, we can uncover the grass curtain early and release the grass curtain late, wipe the drip-free greenhouse film every 3-5 days, remove the grass shavings and dust on the film, and hang the reflective film on the back wall of the sheet. increase the light intensity in the shed; in case of continuous rain and snow, photosynthetic promoters can be sprayed to increase leaf photosynthesis.

Water fertilizer when the first melon sits down and grows to 10 centimeters, it can be watered with second water. In the future, zucchini will gradually enter the peak fruiting period, and the management of the greenhouse should be fertilized and watered according to the weather and plant development.

When the greenhouse temperature reaches 20 ℃ at 8: 9 am every morning, the newly opened male flowers are collected, the petals are removed, and the pollen of stamens is gently smeared on the stigma of female flowers. The female flowers can also be coated with 2.4merd of 20~30PPM or 30~40PPM, and between the base of style and petals with a brush. The effect is better if artificial pollination is combined with 2.4merd or antinol.

The hanging vines pull a thin steel wire from north to south 1.8 meters above each row of zucchini, and each zucchini is tied with a rope, the top of which is tied to the thin wire, and the lower part of the rope of zucchini must be tied into a living knot, so that the plant will not tilt to one side in the future. Leave one end of each plant when hanging the vine, and wipe off the rest of the axillary buds as soon as possible. At the same time, it is necessary to often get rid of the old leaves that have lost their function at the bottom and are withered and yellow, so as to reduce nutrition consumption. Zucchini in the growth process, easy to give birth to a lot of tendrils, in order to save nutrition, tendrils should also be wiped off as soon as possible.
