What are the main points of management of “three-three-three†in summer vegetable management? Summer vegetable management “7, 3, 3†refers to seven key points, three no, three bogey. In summer, due to rising temperatures, increased rain, and crops entering a period of vigorous growth, it is particularly important to strengthen field management. Therefore, Xiaobian said that the management of summer vegetables management is “three three threeâ€. The details will be detailed below. explain. [seven key points] First, the ridge ploughing soil Large ridge cultivating loose soil can improve soil fertility and soil permeability, promote rooting of vegetable plants, reduce root rot, and reduce surface salt damage caused by long-term fertilizer application. Second, planting roots and soil Solanaceous vegetables often die from diseases such as rhizome rot, blight, verticillium wilt, and bacterial wilt, and the root-salt can be degraded by planting roots under the plant to inhibit disease and prolong the fruiting period. Third, remove the old leaf disease leaves Solanum, melons, beans, etc., by removing old leaves and diseased leaves, can make full use of nutrients and nutrients to reduce pests and diseases. Fourth, diligent plant nutrient Replenishing plant nutrients can increase photosynthetic production and increase yield. V. Regular prevention and control of epidemics Due to the high temperature and rain in May, Phytophthora bacteria are occurring rapidly, so it is necessary to strengthen the prevention of the disease. 6. Adding bio-organic fertilizer Add bio-organic fertilizers, such as biological fertilizers (such as phosphate-dissolving bacteria, potassium-dissolving bacteria, actinomycetes, etc.) to improve fertilizer utilization and improve fruit quality. Seven, ventilation and moisture insulation According to the weather, crops, growth conditions, etc., take early air outlets, open air outlets, and half an hour in the middle of the night to do the ventilation and cooling measures. [three do not] First, do not water at noon Watering at noon will cause the roots of the vegetables to “fried†after the cold water stimulation, reducing the yield, and the optimal watering time is before 10:00 in the morning. Second, do not flood the water Large water flooding will cause water accumulation, root respiration is inhibited and prone to rotten roots, which seriously affects vegetable yield. Therefore, it is best to alternate watering. Third, don't let dry and wet Don't let dry and wet easily make the speed of fruit enlargement and crack fruit, especially in tomato and melon crops. [three bogey] First, avoid excessive water control Long-term control without watering will cause the plants to wilting due to lack of water. It is easy to affect the absorption of medium and trace elements by the soil drought, which causes the occurrence of viral diseases. Therefore, it is best to take small measures. The watering method of watering is to determine the watering time and frequency according to the dry and wet conditions of the soil in the shed and the weather conditions. Second, avoid excessive leaf thinning The leaf smear should be moderate, follow the principle that the upper leaves of the fruit are “more than not squeezed†and the leaves of the lower part of the fruit are “small and fineâ€. Excessive smearing of the leaves will cause direct sunlight to cause sunburn and reduce the quality of the fruit. Third, avoid the top air outlet without insect net There is no insect net in the top air outlet, which will cause crops to be invaded by pests, such as aphids and thrips, to reduce the yield and quality of vegetables. Semi Automatic Video Measuring Instrument Features of semi-automatic image measuring instrument:
Automatic zoom optical telephoto lens is a lens specially designed to correct the parallax of traditional lenses. It can be used within a certain object distance range to ensure that the magnification of the obtained image does not change with the change of object distance. This is an important application for situations where the measured object is not on the same surface.

The main body of the equipment is made of high-precision natural granite, which has stable temperature characteristics and resistance to aging deformation, ensuring measurement stability and long-term accuracy.
High precision fully closed-loop automatic zoom optical lens
Telecentric optical principle: Adopting a parallel light path optical design, the size of the object's image does not change with the distance from the lens, resulting in additional measurement errors in the perspective effect.
