In late July and July, the temperature in greenhouses and sheds is high and it is not suitable for the growth of vegetables. In management, it is necessary to gradually release the wind, first put the shoulder wind, the top wind, and finally put the bottom wind, from small to large, do not close the air around the clock. After the exercise, the vegetables gradually adapt to the external climatic conditions, grow vigorously, stabilize production and high yield.
Second, reduce the temperature in the greenhouse, arch shade cover shade net, can make the temperature within the shed reduce about 10 °C, through the cooling can also reduce the incidence of viral disease.
Third, pest control summer air and soil temperature is high, high humidity, vegetables, pests and diseases easily occur. The melons are mainly responsible for the prevention and control of diseases and pests such as epidemic diseases, downy mildew, wilt disease, and thrips, etc. Solanaceous fruits mainly control the prevention and control of diseases and pests such as epidemics, M. blight, and ticks; beans mainly catch rust, blight, and pods. The prevention and control of pests and diseases such as cockroaches and leaf miners.
Fourth, rational watering by adding water to increase the humidity of the shed is another key measure to reduce the temperature inside the shed. 3-5 days to pour a water, each time the amount of watering should not be too large, it is necessary to dilute the ground water, it is best to interlace or septum pouring, so that although the water is poured more frequently, but the amount of watering is not too large, ie It can meet crop growth and reduce the temperature in the shed.
V. Reasonable fertilization Most of summer eggplant, melon, and beans enter the harvest period. At this time, the stem and leaf growth and flowering results of the plant require large amounts of nutrient supply, and the fertility required for most vegetables increases. To this end, it is necessary to combine cultivating and weeding, and increase N, P, and K fast-acting fertilizers to meet the needs of the high yield of vegetable crops. However, when using chemical fertilizers, it should be noted that each quantity should not be too thick. Irrespective of irrigating or dry application, they should not be applied to the sides or plants of the plants so as not to burn them. Leafy vegetables should be applied immediately after rain.
In the kitchen, mushrooms are usually fried, roasted, boiled or fried in various dishes to produce a variety of flavors. However, all of these techniques require the use of butter or oil, which ultimately increases their fat value, which increases the amount of cholesterol consumed. However, like vegetables, mushrooms are cholesterol-free foods. Edible mushrooms in edible mushrooms have a cholesterol-lowering effect, probably due to dietary fiber such as beta-glucan, which may increase intestinal motility and reduce the absorption of bile acids and cholesterol.
