In order to do a good job in the production of vegetables in the fall season, special measures must be taken in a targeted manner. The specific requirements are as follows: 1. Cultivation of ridge or sorghum: Cultivation must be carried out with ridge cultivation or sorghum cultivation. The ridge cultivation should be carried out using a large ridge and double row method, so that it is beneficial to rain drainage. Watering in dry conditions cannot collect water. The sorghum planted sorghum should be about 10 cm above the ground. 2. Casting Garden: In the summer, it must be done immediately after the hot rain. Only in this way can the hot rainwater in the clay be replaced and the ground temperature reduced to facilitate the normal metabolism of the plant roots. 3. Watering when drought occurs: Drought needs to be watered, but it must be watered in the afternoon or in the evening, and it can be poured with a small amount of water, which has a cooling effect. However, watering should be prevented at high temperatures to prevent wilting of plants. On the other hand, it is best not to water when it is cloudy. 4. Timely drainage and flood control: During the whole growth period, we need to keep the soil moist vegetables, usually with a small amount of water often poured, such as green peppers to be poured water (commonly known as stealing water), but it must not be stagnant water, timely drainage after rain . 5. Can not loosen: During the summer, the vegetable field generally does not loosen, not to plow, so as to avoid too much humidity in the soil. 6. Adjust the density of seedlings appropriately: During the summer, the summer vegetables sown during the summer should be dilute to the leafy vegetables, and they must be planted on the ridge back or in the sorghum to prevent the plants from getting too close to the surface leaf rot; The fruits and vegetables should be sparsely planted. Because during the over-summer period, the old leaves of the lower part have been lightened, and the upper branches and leaves have grown vigorously, which can protect the fruits from being burned by strong sunlight. This is also beneficial for surface ventilation and lowering of the ground temperature, and can also reduce weed growth. 7. Scientific use of herbicides: In order to prevent overgrown weeds in over-summer fields, selective herbicides can be selected. Generally, herbicides can be sprayed on the soil before or after seeding; when the seedlings are excavated, the herbicides are exterminated. Weeds should be sprayed in a directional manner (weeds are sprayed only with herbicides), weeds can be used to kill monocotyledonous weeds, and weeds are used to kill dicotyledonous weeds. We must also master the usage and dosage, and we must increase the sowing of vegetables. (or planting) density to prevent killing when spraying herbicides. 8. Buckle shade net or insect net: In order to reduce the damage caused by high temperature, strong light and heavy rain during the over-summer period, the shade net should be deducted. If it is still harmful to the ticks, a silver-gray shade net should be detained; if it is to prevent various pests, it should be in the shed. In indoor production, the soil and sheds are first insecticide treated, and then all the doors and windows and ventilation holes are sealed with insect nets or curtains of insect nets are hung. When you hang the black shade net, you must pay attention to the crop's need for light. Generally, the gray shade net can meet the need of light. 9. Plant regeneration: Some fruit and vegetable vegetables are pruned during the summer to make the plants renewed, so that the peak of the results can occur again after summer, such as eggplant and green pepper. (1) Pruning technology for eggplant regeneration. Pruning time is usually carried out in July before the high temperature. The method of pruning is to cut the growth point (tap) on the eggplant several times before trimming to promote the growth of lateral branches and lateral buds. Pruning starts after half a month, that is, in the second quarter of the four-side bucket of the plant. Cut off, cut and cut out with a black plastic film to cut the mouth, and then in the afternoon when the sun is weak watering fertilizer, Mushi urea 15 kg, to facilitate the promotion of collateral lateral bud growth. When flowering, 40 micrograms/gram of anti-dropping agent can be sprayed to protect the fruit. After the above treatment, flower buds can appear after two months, small fruits appear one month later, and harvest can be harvested in about 10 days and enter the second harvest period. (2) green pepper pruning regeneration technology. In the July-August months, the green pepper plants were repeatedly used to promote the growth of lateral branches and lateral buds. After half a month, they were cut off at the 2-3 sections of the plant's four sided buckets. The cut was sealed with a black plastic film, and then in the afternoon. Topdressing watering, applying 15 kg of urea per acre, which is conducive to the growth of lateral buds; when the buds of the cut plants appear, choose the cloudy days or sunny afternoon afternoon with the buds of buds, and after one month, the second pods will be harvested. 10. Promotion of vegetable grafting technology: For fruit and vegetable vegetables with a long growing period, most of them are spring sowing, and they can grow in summer and fall in love. By grafting, the resistance of the plant can be enhanced, the vitality of the plant is prosperous, and not only the growth period and the harvest period are prolonged, but also the quality and yield can be improved.
