High-yield cultivation techniques of cowpea

Beans are also called cowpeas, and their habits and cultivation techniques are similar to those of green beans. Although the growth characteristics of beans are nitrogen-fixing bacteria, they are harvested from tender pods and fresh beans, so nitrogen supply is indispensable, especially in the early stage. Nitrogen: Phosphorus: Potassium = 1:0.6:1.3, trace element molybdenum can promote the vigorous development of nodule, beans are also sensitive to trace elements such as boron and zinc, so on the basis of reasonable application of N, P, K fertilizer, spraying Boron fertilizer, molybdenum fertilizer and zinc fertilizer have certain effects on increasing the pod-forming rate of beans, promoting grain fullness and increasing yield. Let's talk about the high-yield cultivation techniques of beans. Because the rhizobia is aerobic in roots, this is one of the reasons why kidney beans can withstand short-term soil drought and poor moisture resistance.
First, the sowing of the whole land is suitable for the fields that have not been planted with beans. It is necessary to disinfect the land because it is very prone to root rot and blight, causing the dead vines of the beans, which is difficult to control.
1. Disinfection. 1 mu with quicklime 60 ~ 80 kg of polder, 7 to 10 days after drainage, whitening; 2 can be used potassium permanganate 500 times before planting, or Beans fear (also available as carbendazim or fungus Zhen 2) ) + Bellin (Plus Jia iodine) 500 times liquid pouring soil wet more than 3 cm deep.
2, according to the height of the ground, choose to do the ridge, the ridge surface is about 40 cm wide and 30 cm high. Open a small ditch of 10 cm deep in the ridge, and use 1000 kg of decomposed manure to drench the ditch. After drying, loosen the soil, choose suitable varieties, seed soaked for 4 hours, soaked in water, seed dressing with chlorothalonil powder, 25 grams per 500 grams of seed powder, sowing in small ditch, single planting, every 20 cm seeding Two seeds, covered with soil or fire soil after sowing, and drenched.
Second, the seedling period management two days after sowing according to the dry and wet conditions of the ridge surface, to ensure the water required for emergence, after 5 to 6 days when the soybean meal has two leaves and one heart, with the bacteria poison clear 800 times plus Jinggangmycin 300 times Once again, 750 kg of liquid was used to prevent root rot and disease. And time seedlings, guaranteed one per 20 cm. When taking the medicine, pay attention to the medicine particles and do not touch the plants. Appropriate fertilization according to the growth of soybean meal, the use of urea 3 to 5 kg, plus the same amount of potassium fertilizer to 1000 to 1500 kg of water, after the application of thin water. Prevention and control of soybean meal is the focus of the seedling stage. The damage of the young heartbeat of the cardamom horse is also the common tipless extraction. Only two leaves are seen, commonly known as the blind heart. Prevention and control of soybean meal can be 600 times of heptaphos and 600 times of benefit, or 1500 times of avermectin plus 1500 times of imidacloprid, or 500 times of good winter plus 1500 times of 5%, and spray once every 6 days. Spray 1 or 2 times Yunda 120.
Third, the management period of the cardamom has a vine extraction, to carry out large cultivating soil, combined with fertilization, 30 kg of phosphate fertilizer plus 10 kg of urea, applied evenly on both sides of the ridge, covered with fertilizer and weeds with ridge soil, pay attention to fertilizer and soil Do not touch the bean stems. It is possible to apply 2,000 kilograms of manure fertilizer to the soil and cultivate the soil on the ridge side. After cultivating the soil, leaching with a thiamine mixture, using 1 kg of copper sulfate, 2 kg of carbonamine and 1000 kg of water. At the same time, the vines are put on shelves, generally with a herringbone frame. The seedlings are long and can be used with a conical frame, that is, every 40 cm, three bamboos are inserted into an equilateral triangle, and the ridge surface is tied with a rope into a cone, and the upper side frame is a horizontal bamboo. For the convenience of operation, the height of the scaffold should be controlled at 2 meters. Within. The cone can increase production by more than 10% compared to the herringbone frame. Control the water, fill the horse water once every 3 days on a sunny day, and at the same time wet the ridge surface, pay attention to drainage when it rains. The pests and diseases of the vines are mainly rust, powdery mildew, soybean meal, soybean meal, and can be used for powder rust (800-500 times) plus sulphate 500 times plus 800 times of sapphire, or 600 times of sage plus 600 times of universal powder. 800 times, pay attention to the concentration of pink rust from light to thick (800 ~ 500 times), spray once every 7 days, spray cloud 120 every 14 days.
Fourth, harvesting management for about 60 days, the plant enters reproductive growth, the harvest period appears, fertilize once every 7 days, each time with 10 kg of compound fertilizer plus 5 kg of urea, mixed with 100 kg of manure for 3 days, add water 1500 kg applied to the ridge surface, after application, drenched thin water, or applied in the ridge edge, 20 kg of compound fertilizer plus 10 kg of potassium fertilizer plus 10 kg of urea, and applied at a hole of 35 cm on the side of the ridge. After 10 days, apply the same amount of fertilizer on the other side. Before the application of the hole, the water should be drenched. Do not spray water on the ridge surface within two days after application, and do not apply fertilizer on rainy days. The harvest should maintain 1 to 2 cm of water in the furrow. Pest control can be selected to prevent spot blight and disease: 75% chlorothalonil 600 times plus 70% mancozeb 600 times; rust, powdery mildew: 50% colloidal sulfur 300 times, 1000 kg per acre , but only if the condition does not appear to be good, prevention is better than treatment. The insect pests are mainly soybean meal. Available: 1 dish is 1000 times plus imidacloprid 1500 times; 2 avermectin 1500 times plus ampoule 600 times; 3 Bacillus thuringiensis 1000 times plus small insects 800 times. Do not mix the above three agents with fungicides. Since the control of soybean meal is very difficult, the spraying time should be sprayed once every 3 to 4 days, and the effect of opening the bean flower before 10 am is better. Add a cloud of 120 per 7 days. It is advisable to harvest the fog in the morning. Disclaimer: Some articles on this website are transferred from the Internet.

Does the solar PTZ Camera System Kits work well

In fact, there are no network and no electricity cameras, but they have certain limitations. The working time of a camera with batteries or external solar panels is limited.
Monitoring without network means that mobile phones and cameras can only be seen within a certain range of 5~10 meters.
Therefore, no network and no power is just a gimmick. We must pay attention to distinguish when buying.
Is the Solar Camera easy to use
Jiajie intelligent surveillance camera is very good
Advantages and disadvantages of solar monitoring
Probably.
Generally, offline display has the following two conditions.
One is that the installed 4G card has no traffic and cannot provide network connection for monitoring;
The other is that there is a problem with the signal receiving device, which makes it unable to connect to the network. Therefore, the user can access the APP connected to the monitor to check whether there is still traffic on the 4G card. If there is still traffic, there is a problem with the monitoring; If there is no traffic, the renewal fee can continue to be used.
Which is the best solar Outdoor Camera
It may be that the poor contact of the power plug causes power on, heating and power failure, or it may be that the camera's internal control motherboard fails, causing power on for several minutes and automatic power off protection.
The camera works continuously, and the internal chip may overheat, which also exists in many SLR cameras. Some cameras impose time limits on continuous shooting. Centralized power supply with high-power switching power supply
Disadvantages of camera solar power supply
