How to achieve high yield in Chinese cabbage cultivation? Chinese cabbage is one of the vegetables that many men, women and children love to eat. It tastes sweet and nutritious. Today, Huinong.com Xiaobian today introduces 10 ways to increase the yield of Chinese cabbage, and learn quickly!
First, spray double-effect micro-fertilizer
Spraying 800 times and 600 times of double-effect micro-fertilizer solution in the rosette and the core period can prevent the treatment of downy mildew, soft rot, virus disease, etc., and improve the quality, which can increase production by 20% to 35%.
Second, spray rare earth
In the rosette period, the ball-forming period and the core period, 0.03%, 0.05%, and 0.08% of rare earth nitrate solution were sprayed respectively for 3 times, which could increase production by 10%.
Third, spray grass ash
From the beginning of the rosette period to the ball before the ball, spray 0.5% of the ash ash leaching solution for 5 to 7 days, and spray a total of 2 times, which can increase the yield by about 15% and improve the quality.
Fourth, spray borax
In the rosette period and the core period, 0.15% borax or 0.1% boric acid solution is sprayed twice, and the fertilizer solution is 30-60 kg per 667 square meters, which can increase the yield by 10% to 15%.
Five, spraying rice vinegar
During the rosette period from the cabbage to the ball-forming period, spray 300-500 times of vinegar, spray once every 7 to 10 days, and spray 2 to 3 times, which can increase production by 15% to 30%.
Sixth, spraying calcium chloride
During the rosette period from the cabbage to the core period, spray 0.7% calcium chloride solution every 7 to 10 days for a total of 3 to 5 times to prevent the cabbage from burning.
7. Spray urea
From the rosette period, spray 0.2% to 0.5% of urea solution every 10 days for a total of 2 to 3 times, which can increase production by 15% to 20%.
Eight, spraying potassium dihydrogen phosphate
During the rosette period to the ball-forming period of the Chinese cabbage, 0.3% to 0.5% of potassium dihydrogen phosphate solution is sprayed once every 7 to 10 days, and even sprayed 2 to 3 times, the net weight of Chinese cabbage can be significantly increased, and the yield is increased by 15%. ~25%.
Nine, spray leaf treasure
In the rosette period, the ball-forming period, and the core period, respectively, spraying 6,000 times of the leaf-faced treasure each time, which can increase the yield by more than 15%.
X. Spraying the core agent
In the period of the ball-wrapping period, 100 grams of Chinese cabbage anti-corrosion core agent per 667 square meters, spraying 30-50 kg of water, can increase production by 15%, and has soft rot, black heart disease, dry heartburn, etc. Control effect.
These methods must be used on the basis of reasonable fertilization and watering, and some can not be mixed arbitrarily, such as potassium dihydrogen phosphate and rare earth solution, and should not be mixed with alkaline pesticides when spraying. Favorite vegetable farmers can collect first!
What is DVR Mini Camera
Dvr, which is called DigitalVideoRecorder in full, is a digital video recorder. Compared with traditional analog video recorders, dvr uses hard disk for recording, so it is often called hard disk recorder, also called DVR. It is a set of computer system for image computing, storage and processing. It has the functions of long-time video recording, recording, remote monitoring and control of images/voice and dynamic frames. DVR integrates five functions, including video recorder, picture splitter, PTZ lens control, alarm control, and network transmission. One device can replace a large number of devices in the analog monitoring system, Moreover, it has gradually gained advantages and popularity in terms of price.
The "digitalization" of DVR means that compression and storage technology is aimed at digital signals, rather than directly transmitting digitally encoded video images. Therefore, DVR must be deployed near the analog camera.
The function of DVR, with the increase of various voltage sensitive loads in the distribution network, puts forward higher requirements for power quality. However, due to system accidents in the power system, the voltage flicker, drop and other disturbances caused by the startup and shutdown of large equipment, lightning stroke and other principles are unavoidable. Moreover, in the current power grid, the ability to quickly restore power supply after power interruption is far from meeting the requirements of many sensitive loads. Therefore, it is necessary to provide users with stable and uninterrupted high-quality power when interference occurs. Dynamic voltage recovery (DVR) is the choice to solve the above problems today. DVR is connected in series to the feeder line that requires high-quality power to realize dynamic real-time voltage compensation for the line, so that the load end can get the desired high-quality power, and ensure the normal and uninterrupted operation of sensitive user equipment.
