Summer food management four key

    First, the temperature - with temperature control, to warm and strong

      Temperature is a key factor affecting the growth of vegetables. The temperature is high, especially when the night temperature is too high, which is easy to cause vegetables to grow. Therefore, regulating temperature is one of the technical points for cultivating vegetables and strong trees.

      For the summer vegetables, because the growth is in the high temperature period, the shed often exceeds 40 °C, which affects the normal growth of vegetables. Therefore, in addition to increasing ventilation, it is also necessary to pay attention to the application of sunshade and cooling agents such as sunshade nets and cooling agents. Try to increase the temperature difference between day and night to prevent vegetables from growing.

      Second, moisture - water to promote roots, large and small water

Soil moisture is an essential ecological factor for vegetable growth. However, if there is too much watering and overwork, the vegetables tend to prosper, which is not conducive to the cultivation of strong trees. In general, summer vegetables should pay attention to the combination of large water and small water, so that it can not only meet the water required for vegetable growth, but also reduce the temperature of the greenhouse. However, it is forbidden to water the water at a high temperature at noon. Generally, it should be selected before 10:00 am and after 4:00 pm.

Of course, watering should also be carried out according to the water demand characteristics of different vegetables. For example, melon vegetables have a large demand for water, and the number of watering can be appropriately increased. In addition, some vegetables are wet but afraid of drought and drought. After planting and slowing down the seedlings, the measures of water control can be used to ensure soil moisture and control plant growth. Do not water and work too hard to prevent root suffocation or plant growth.

      Third, nutrients - to improve soil with fertilizer, to root with fertilizer

The cultivation of summer vegetables is high, and the temperature of the ground is high. The vegetable farmers do not use ridges for planting, and most of them are cultivated in flat sorghum. Flat cultivars have poor gas permeability and are not conducive to root growth. In order to solve this problem, the bio-fertilizer can be applied at the point of cultivation of the sorghum, and the effect of the biological bacterium to improve the soil and roots and roots can be fully utilized to cultivate the strong trees and improve the disease resistance and resilience of the plants.

In addition, for plants that are too weak, it is possible to spray chitin and apply biological fertilizer to promote the growth of the tree.

      Fourth, prevent disease - early set up insect nets, early spraying

For the summer vegetables, affected by adverse environmental conditions such as high temperature and high humidity, the occurrence of pests and diseases is more serious, so it is necessary to prevent early treatment. In general, pests invade from the ventilator of the shed. Therefore, in order to reduce the occurrence of pests in the shed, it is best to set up an insect net at the upper and lower vents of the shed.

In addition, after the summer vegetables are planted, epidemics, viral diseases, bacterial leaf spot, etc. often occur, and drug protection can be sprayed before the disease occurs. For example, the disease can be controlled by 7 77.2% Plex water 600 times solution; the virus disease can be controlled by 500 times virus A mixed with Ningxia 300 times liquid; the bacterial leaf spot can be used 47% Garrinone WP 600 times solution Prevention and control can effectively control the development of diseases.      Xue Yuxia
