In order to do a good job in vegetable production in autumn and off-season, some special measures must be taken. The specific requirements are as follows:

1. Ridge cultivation or high border Cultivation: ridge cultivation or high border cultivation must be adopted. Ridge cultivation should adopt large ridge double row cultivation method, which is conducive to rain and drainage, and watering can not accumulate water in drought. The border surface of high border cultivation should be about 10 cm higher than the ground vertical farming racks.

2. Waterlogging irrigation Garden: in summer, it is necessary to "waterlogging irrigation garden" in time after hot rain. Only in this way can the hot rainwater in the border soil be replaced and the ground temperature be reduced, which is conducive to the normal metabolism of plant roots.

3. Less watering in drought: watering is required in drought, but it must be done after the light weakens in the afternoon or at night, and a small amount of water ...
... can be poured frequently, which has a cooling effect. However, it is necessary to prevent watering at high temperature to prevent plant wilting. In addition, it's best not to water on cloudy days.

4. Timely drainage and waterlogging prevention: vegetables that need to keep the soil moist during the whole growth period are usually watered with a small amount of water. For example, green peppers should be watered with small water (commonly known as stealing water), but they must not accumulate water. They should be drained and waterlogged in time after rain.

5. Can not loosen the soil: during the summer, the vegetable field generally does not loosen the soil, let alone plough, so as to avoid too much soil humidity.

6. Properly adjust the seedling density: for the over summer vegetables sown during the over summer, the seedlings of leaf vegetables shall be thinly fixed, and they must be planted on the back of the ridge or in the high border to prevent the plants from being too dense and the near surface leaves from rotting; For fruits and vegetables over summer, they should be thinly planted. Because during the summer, the old leaves in the lower part have been polished, and the branches and leaves in the upper part grow vigorously, which can protect the fruits from being burned by strong sunlight, which is also conducive to surface ventilation, reduce ground temperature and reduce weed growth cannabis grow racks.

7. Scientific use of herbicides: in order to prevent overgrowth of weeds in summer vegetable fields, targeted herbicides can be selected. Generally, herbicides can be sprayed on the soil before sowing or before emergence after sowing; When the seedlings are unearthed, the grass should be sprayed. The weeds should be directed to spray (weed only with herbicide), kill the single leaf weeds, use the cover grass to kill the dicotyledonous weeds, and use the dosage. In addition, the density of planting (or planting) should be properly increased, so as to prevent the phenomenon of killing seedlings when spraying herbicides.

8. Buckle shading net or insect prevention net: in order to reduce the harm of high temperature, strong light and rainstorm during summer, buckle shading net. If it is also harmful to aphids, buckle silver gray shading net; If it is necessary to prevent various pests, it should be produced in the shed. First, the soil and the shed should be treated with insecticides, and then all doors, windows and vents should be sealed with insect proof nets or hung with insect proof net curtains. When hanging the black shading net, we must pay attention to the needs of crops for light. Generally, the gray shading net can meet the needs of light.

9. Plant regeneration: some fruits and vegetables are pruned during the summer to renew the plants, so that there can be another fruit peak after the summer, such as eggplant and green pepper.

(1) Pruning technology of eggplant regeneration. Pruning is generally carried out in July before high temperature. The pruning method is to cut off the growth points (TIPS) of the eggplant for many times half a month before pruning to promote the growth of side branches and side buds. After half a month, start pruning, that is, cut off the second section on the fruit branches of the plant, wrap the cut with black plastic film, and then water and top fertilizer when the sun is weak in the afternoon. Apply 15kg urea per mu, In order to promote the growth of lateral branches and buds. In order to protect flowers and fruits during flowering, 40 μ g / g anti falling element can be used to spray flowers. After the above treatment, flower buds can appear after half a month, and small fruits can appear after a month. They can be harvested in about 10 days and enter the second harvest period.

(2) Green pepper pruning regeneration technology. From July to August, prick the green pepper plant for many times to promote the growth of lateral branches and lateral buds. After half a month, cut it off at the first 2-3 sections of the four sides of the plant, seal the shear mouth with black plastic film, and then Topdressing and watering in the afternoon, applying 15kg urea per mu, which is conducive to the growth of lateral buds; When the flower buds appear on the cut plants, dip the flower buds with anti falling element in the afternoon of cloudy or sunny days, and start harvesting the second crop of fruits one month later.

10. Promote vegetable grafting technology: for fruits and vegetables with long growth period, most of them are sown in spring, which can grow over summer and love autumn. Grafting can enhance plant resistance and plant vitality, not only prolong the growth period and harvest period, but also improve quality and yield.
