The latest methods of planting green beans

Green bean is one of the most important food crops in China. It has strong adaptability to the environment and is planted in all parts of our country. The most famous producing area of green beans is in the northeast. Green beans are rich in nutrients. The use of green beans can maintain the elasticity of blood vessels, reduce the content of cholesterol in the blood and nourish the liver and stomach. At the same time, it has a certain curative effect on prostatitis, liver cancer, skin cancer and so on. So how to grow green beans? The editor has brought you the method of planting green beans today. if you are interested, you can learn about it.

1. Seed selection and soil preparation

The resistance of green beans in all aspects is relatively strong, generally speaking, we only need to choose seeds that are full and not damaged by diseases and insect pests, followed by those that have been planted for too long, and the budding rate is very low. there are green beans divided into green skin green beans and green skin yellow kernel green beans, you can choose the most suitable varieties according to the market situation. Generally choose the soil which is relatively loose, well drained, and the previous crop is not legumes, melons and eggplants. When preparing the soil, dig deeply, clean up the remaining pest eggs in the field, and then sprinkle sufficient base fertilizer to mix well and plant.

2. Sowing and raising seedlings

There are actually two ways of sowing. The first is hole sowing, which is to sow three or four seeds in the right soil at the right density to wait for emergence. The second is to sow and raise seedlings. First of all, the seeds are evenly scattered in the seedling bed to raise seedlings. After a period of seedling emergence management, the seedlings can be transferred and planted, while the sowing time of green beans is generally from the end of May to the beginning of July every year. The emergence rate of sowing during this period will be higher.

3. Transplanting and planting

Before planting, you can sprinkle an appropriate amount of ternary compound fertilizer in the field, which can not only increase production, but also improve the quality of green beans and increase its commodity value. Then plant according to the density of 50 centimeters per behavior and 45 centimeters per plant, and you can sprinkle one gram of carbofuran next to each plant when planting, so as to control some underground pests.

4. Field management

A week after planting, check the growth of green bean seedlings in the field, even if there is a phenomenon of dead seedlings, and carry out watering and fertilization to ensure the evenness of the seedlings in the field, and the second is to wait for the green bean seedlings to grow new branches, leaves and roots. We should carry out fertilization, this period of time is mainly nitrogen and potassium fertilizer, while watering is used to dilute the concentration of nutrients, so as not to cause damage to the roots of green beans. At the same time, ploughing and weeding is carried out to promote the absorption of nutrients. In the later stage, that is, the flowering and podding stage, it is mainly potash fertilizer, and appropriate foliar fertilizer is needed at the same time.

5. Pest control

The most harmful disease to green beans is downy mildew, which can be prevented by strengthening field management. at the same time, chlorothalonil can be used to control the disease at the initial stage of infection, once a week and sprayed two or three times. The main pests are bean pod borer and heart borer, we can use dimethoate and fenvalerate respectively, or we can use trichlorfon and methamphetamine granules, the effect is also very good.

6. Timely harvest

Green beans should pay attention to the time of harvest. Generally speaking, we need to harvest green beans when the pods are relatively full and slightly yellowish green. We cannot wait until the pods become yellow and old, so the green beans are not young. At the same time, we also need to keep seeds. The pods left behind can not be harvested until they are very hard. Of course, we can not wait for the pods to be harvested when the pods are split, so the loss will be greater.
