Cultivation techniques and management methods of Dutch bean

Dutch bean planting is a good planting project, but the planting technology of Dutch bean is not complicated. The Huanghuai Basin is mainly planted in spring, and other areas should decide the sowing date according to the local geographical and climatic conditions. The planting techniques and management methods of Dutch beans are introduced as follows:

First, how to prepare soil and fertilize before planting Dutch beans

After harvesting late-maturing crops such as cotton, rice and sweet potato, clear stubble and prepare soil in time. During soil preparation, 3000 kg of organic fertilizer, 50 kg of urea 10, 50 kg of calcium superphosphate, 5-20 kg of potassium sulfate/kloc-0, and plant ash can be added appropriately in case of plant ash.

After clearing the land, make an east-west ridge 2 meters wide, 25 centimeters high and 20 centimeters wide.

Second, the sowing and methods of Dutch beans

When sowing, you can choose short varieties with large pods, such as Cuifeng Dutch beans, which are generally 12 ~ 16 cm long and are very popular in the market.

The suitable sowing date in Huanghuai River Basin is generally from 65438+1October 25th to165438+1October 5th. If the sowing date is too early, the seedlings will grow white and freeze easily before the year. In the Jianghuai area where the temperature is high in winter, the sowing date can be postponed to the middle and late of 10.

When sowing, if the soil moisture is not good, you should water with the hole, but avoid watering after sowing and before emergence, so as not to affect the emergence.

Sowing can be divided into large and small rows, big row 60 cm, small row 40 cm, plant spacing 20-50 cm, 2-3 seeds per hole. Cover the soil for 2 ~ 3 cm after sowing.

Third, the field management technology of Dutch bean planting

Before winter, the seedlings are crawling, so shallow intertillage can be carried out appropriately, and according to the weather forecast, before the cold current comes, cover the seedlings with a plastic film. In the northern region where the temperature drops to-12℃ in winter, corn stalks can also be used to set up east-west wind barriers.

Before and after beginning of spring, when the temperature rises, it is necessary to hoe the soil in time, raise the ground temperature, water it once in combination with the soil moisture, and topdressing the seedling fertilizer (generally urea 10 kg) to promote the plants to blossom and set pods as soon as possible. A small arch shed can be built where conditions permit. Covering with a small arch shed can make Dutch beans go on the market 15 days in advance, and the benefit is higher.

In early March, cotton stalks and branches can be slightly supported to make the field fully ventilated and transparent. This measure can obviously increase the output by about 20%.

Urea 10 kg and 15 kg were applied at the early flowering stage and the full flowering stage respectively, and a small amount of water was frequently used.

Four. Harvest and pest control of Dutch beans generally take 7 ~ 10 days to bloom. The first batch of beans should be picked with scissors as much as possible to prevent the stems and vines from turning over and affecting the yield. If cabbage caterpillar and stem borer occur in the later stage, pyrethroid pesticides and phoxim can be used for control.
