In the summer high temperature period, to control the growth of vegetables is too prosperous, and to prevent the occurrence of the problem of no fruiting only, the following five measures can be taken:
Moderate watering in the early stages of vegetable growth, in order to prevent plant growth, to control temperature, water control and fertilizer control. In particular, watering, not too much work, the soil as long as it is not too dry, try to control the watering, so as not to cause plant growth, while spraying a new high-fat film powder heat preservation to prevent the spread of gas-borne pathogens.
Less application of available nitrogenous vegetables in the cultivation process, especially the fruiting period of the fruiting squash, is often caused by too much nitrogen fertilizer, resulting in excessive growth, serious drop and fruit drop. Therefore, it is recommended that the amount of nitrogen fertilizer used by vegetable farmers should not exceed 20 kg per mu.
Nutrition regulation is regularly regulated with plant growth regulators, such as harvest 1 1000 times, or love more, Yunda 120 and so on.
Scratching and cutting off roots When vegetable plants grow too profusely, they can be controlled by cutting. On the one hand, soil permeability can be increased. On the other hand, some root tips can be cut off, which is conducive to secondary root rooting.
In order to control the pests and diseases timely, the plants with severe growth should be promptly sprayed with Huahua No. 3 to suppress the prosperous growth of vegetables and promote the differentiation of flower buds. It can be used to spray 800 times liquid with the new high-fat film powder. kill.
New product of U85 micro laser distance sensors use highly focused class 2 laser to detect objects or measure distances, and can return a measured value via varieties intface( serial, usb, rs232, rs485, bluetooth etc.). The electronic distance sensor is a very small Laser Distance Sensor, but high resolution up to 1mm and long distance measuring sensor - teachable measuring range of up to 30m. Extremely accurate distance sensing sensors, errors down to ± 1mm. And the mini sensors and measurements support continuous measurement function, great for compact solutions(eg: robots) with the smallest Laser Distance Sensor of the world!
