Weeding: weeding needs to be done in time during planting. Manual or chemical weeding can be used. Disinfection: soil disinfection should be carried out in time during planting. Fields with more diseases can be sprinkled with quicklime, and then ploughed and mixed.

Kidney bean is often called "kidney bean", which is a kind of food with high nutritional value. The taste of green beans is also very good, and it is very popular with people. Now many people want to plant green beans, but before planting, more people must be more concerned about its planting technology. Let's take a look at it together.

2. The sowing methods of kidney beans are generally divided into seedling cultivation and direct seeding. After the seeds are sown first, the seedlings can be transplanted to the field after the seedlings grow to about 2-3 true leaves. In the case of direct seeding, the seeds will be sown in the field at certain intervals, and each place can choose to sow 2-3 seeds. The choice of the two methods depends on the conditions of the growers themselves.

Planting techniques and management methods of green beans

Common diseases of kidney bean and their control

1. Botrytis cinerea is one of the common diseases of kidney bean. There are two methods of agricultural control and chemical control. Next, let's analyze how these two methods are used.

Agricultural control: protected cultivation should adopt high border planting, plastic film mulching, strengthen the ventilation in the greenhouse and reduce the humidity in the greenhouse. Properly reduce the density, remove diseased leaves and pods in time, remove the remains of diseased plants, and destroy them thoroughly.

Chemical control: attention should be paid to inspection in the field and spraying in time when sporadic disease spots are found. If you spray, you can choose 1500 times of 50% Sukeling wettable powder, or 1500 times of 50% Prohydantoin wettable powder, or times of chlorpromazine wettable powder, once every 7 days, 3 times in a row.

2. Anthracnose is not only the most common disease of vegetables, but also the most common disease of kidney bean. The harm of anthracnose is very great. In the process of prevention and control, the seeds are disinfected, soaked in 200x formaldehyde solution, soaked in 30min, washed and dried before sowing.

Rotation with non-legume crops for more than 2 years; selected high dry terrain, good drainage, partial sand soil cultivation. Collect seeds from disease-free pods. At the initial stage of the disease, you can use 75% chlorothalonil wettable powder 600x liquid, or 50% methyl thiophanate wettable powder 800x liquid, or 1purl 240 Bordeaux solution 50kg/667 spray, once every seven days, a total of two sprays can generally prevent and control anthrax.

Green beans in planting, must choose a good time to carry out, generally early spring and autumn is its best planting time. After planting green beans, we also need to strengthen management and timely prevention and control of diseases and insect pests in order to ensure its growth.
