The planting method of beans: like fertilizer, like temperature

Doudou is one of the most abundant vegetables in summer. It is rich in vitamins and minerals, which can prevent and treat acute gastroenteritis, vomiting and diarrhea. So how to breed beans? What good method is there in breeding? What matters should we pay attention to when breeding beans? Please read down with me with your questions!

Planting method of beans breeding method of beans (basic knowledge): the best breeding time: beans are cultivated from late February to late March, planted from late March to late April, harvested from early June to mid August, and harvested from late July to early August. It is planted in mid May to early August and harvested from early July to late October;

The best growing soil is loam or sandy loam which is fertile and loose and has not been planted in 2-3 years;

Growth humidity requirements: beans belong to semi-arid crops, the humidity is about 50%;

The optimum growth temperature was 25-30 ℃ for Bean Germination and 20 ℃ for sowing;

The best growth light: bean is a short day crop, but many of its varieties belong to the light, the requirements of sunshine is not strict.

The planting method of beans the matters needing attention in breeding beans: fertilizer application:

1. Base fertilizer

The base fertilizer was mainly decomposed organic fertilizer, combined with appropriate proportion of compound fertilizer.

Generally, 500-1000 kg of farm manure, 50 kg of superphosphate and 50 kg of ternary compound fertilizer (15-15-15) are used per mu. When the base fertilizer is applied in soil preparation and ridging, a small ditch can be opened on the planting ridge, and then the base fertilizer is put in the ditch and covered with soil. If using this method of fertilization, we must remember that the bean seedlings can not be directly inoculated in the organic fertilizer ditch, to ensure that the distance between the bean seedlings and the organic fertilizer ditch is 10-15 cm. Avoid direct contact with fertilizer and burn the root system of soybean seedlings.

2. Top dressing root protection

According to the above, there is a great demand for potassium and phosphorus during the growth of beans. Compared with general compound fertilizer, the nutrient elements of root protection are all water-soluble, the absorption of beans is 50% faster, the fertilizer efficiency is more than 30%, and the appearance of beans is plump and the color is tender. Therefore, root fertilizer Baoyou is suitable for soybean topdressing.

3. Spraying foliar fertilizer - nongmi 1 or nongmi Da

In the middle and late growth period, beans often show various symptoms of deficiency of trace elements, such as yellow leaves. Foliar fertilizer: nongmi No.1 or nongmi Da should be sprayed at early growth stage, that is, young seedling stage and vine introduction stage. If it is applied when yellow leaves are found, the effect will be greatly reduced.

Watering points:

The beans should be watered once when they are put up, and then when they are flowering and podding. If the vine is too dry, they can also be watered once. In a word, the principle of "watering pods but not flowers" should be mastered.

Breeding points:

Beans are usually sown and propagated.

The seeds of bean are bigger, so the seeds should be soaked in cold boiled water for two days before sowing, or they can be treated with wet paper towel. After treatment, the seeds can be directly sown in the pot soil, and the distance of sowing should be moderate, with about 10 cm as the best, which can avoid overcrowding after emergence, and also can save the trouble of transplanting.

Pest control:

The main diseases and insect pests of beans are coal mildew, rust, aphid, cowpea pod borer and so on. In the early stage of the disease, 50% thiophanate methyl or 50% carbendazim can be used to control the disease. Rust can be sprayed with 50% powdered wetting powder and 1000 times liquid spray, spraying 1 times every 7 days and spraying 2~3 times. Aphids can be controlled by 1 500 times of 10% Juma EC or 2 000 times of 10% imidacloprid. The cowpea pod borer can be killed with 1000 times of 50% phoxim or 4000 times of 21% fenvalerate, once every 7-10 days, and evenly sprayed on the leaves and flower buds.
