As far as greenhouse vegetables are concerned in autumn and winter, no matter whether they are watered for fertilizer, or hanging branches and mulching, they should not be rushed. After all, any farming operation must grasp the opportunity well in order to achieve the best results.
1. Watering at night
After the autumn vegetables are planted, watering should be properly delayed. The purpose of delaying watering is to keep the surface of the soil dry to promote deep rooting. Therefore, after watering the slow vegetable seedlings, you must pay attention to extending the interval of watering again. Do not water the ground as soon as it sees dry, which is not conducive to deep rooting. Pay attention to extend the watering time but do not control the amount of watering. Make sure that the water must be irrigated every time, so as to prevent the soil bottom from being dry, and the effect of rooting will not be achieved.
Second, late topdressing
Under normal circumstances, the period from vegetable planting to before fruiting does not need flushing, especially for autumn vegetables, with sufficient base fertilizer and suitable temperature, it is easy to grow vigorously. Premature flushing of fertilizer will easily lead to excessive nutrients and long light. Kezi does not bear fruit. Therefore, it is generally advisable to start fertilizing after 3-5 fruits on solanaceous vegetables. For example, it is not too late to fertilize eggplant after sitting on the four-door eggplant. For melon vegetables, it is necessary to sit on 2-3 fruits. It is advisable to start flushing fertilizer. Of course, it cannot be generalized. If the seedlings are weaker after planting, you can choose to use less fertilizer for the seedlings, or use some functional fertilizers to control, in order to achieve the purpose of turning from weak to strong.
Three, late hanging branches
After the autumn vegetables are planted, whether it is the hanging branches of nightshade vegetables or the hanging vines of melon vegetables, it should not be too early. Some vegetable farmers are very diligent and think that the above operations have to be done sooner or later, and should be done sooner rather than later. Obviously, this is incorrect. If the bell peppers hang branches too early, the branches will grow prosperously. Cucumber hanging vines are premature and easy to jump over.
Therefore, the hanging branches of autumn vegetables must be slow, anyway, during this period, there is no fruit on the plants, and the branches can not be broken, so why bother to hang them early? Even if hanging branches, everyone has to change the previous hanging methods. The two-row three-wire method is used to hang the branches so that the branches can be lifted around, so that the branches are not easy to close together due to the hanging branches. , It will not cause the inner chamber of the plant to be closed, and it will not cause the branches to grow vigorously.
Fourth, late coating
Late mulching of autumn vegetables is also an agricultural operation that we have always advocated. The purpose is to promote the deep rooting of vegetable roots. Everyone knows that the role of mulch is to keep warm and keep moisture. This undoubtedly creates a suitable environment for vegetable roots on the ground. In this case, the roots lose their motivation to plant. Therefore, the mulching of the autumn vegetables must be late, hoe the soil frequently, improve the air permeability of the soil, and promote the growth and development of the root system, so that the vegetables can grow stronger and have more fruit.
