Third, what are the planting techniques of Dutch beans?

1. Land selection and preparation: what kind of soil is suitable for planting?

Dutch beans have strong growth ability and do not have high requirements for soil. generally, as long as alkaline or neutral soil can be planted, if the soil is alkaline, just sprinkle an appropriate amount of lime into the soil to neutralize the soil. In addition, Dutch beans should be rotated for more than 4 years, so attention should be paid to site selection to prevent the occurrence of diseases and insect pests. After selecting the land, turn the soil deeply, and apply an appropriate amount of farm manure or calcium fertilizer, and then make a field bed to facilitate later planting.

2. Sowing and raising seedlings: how to sow seeds?

(1) seed selection: it is best to sow seeds with glossy appearance, large particles and no damage.

(2) seed treatment: after selecting the seeds, soak them in water for 5 hours, then remove them and let them germinate in a suitable environment. After the white buds are leaked, put them in the first degree environment for half a month. Half a month later, mix the seeds with rhizobium to increase the number of nodules and improve the fruit rate.

(3) sowing method: when the white bud grows to 5mm, it can be sown on the seedling bed. When sowing, sow seeds according to plant spacing 8~10cm, row spacing 30~40cm spacing. Then slowly cover the soil with 2~3cm.

(4) seeding rate: in general, dwarf species use about 15 kg per mu of land, and trailing species use 12 kg per mu of land.

3. Field management: how to manage?

The main results are as follows: (1) Water requirements: Dutch beans do not have high water requirements, so it is generally possible to pour appropriate amount of water after emergence and before flower buds, and the rest of the time, the amount of water can be determined according to the dry humidity of the soil.

(2) Fertilizer requirements: Dutch beans do not have high requirements for fertilizer. 15 kg of compound fertilizer or 400 kg of manure per mu can be applied in the growing period, and 15 kg of ammonium fertilizer and 5 kg of potash fertilizer can be applied per mu in podding period. In addition, nitrogen fertilizer should be applied before flowering to promote plant growth.

(3) picking the heart and picking leaves: when the Dutch bean grows to 15 nodes, the heart should be removed, and the surrounding yellow leaves and old leaves should be removed in time to ensure good ventilation. In addition, anti-falling element spray can be properly sprayed to avoid falling flowers and fruits.

(4) loosening soil: after successful sowing of Dutch beans, it is necessary to loosen the soil in time to increase the soil temperature and promote the seed to take root and germinate. If sowing in autumn, the soil can be cultivated before the beginning of winter to ensure that it can survive the winter safely.

(5) scaffolding: when the Dutch bean grows to about 35cm, it is necessary to set up a vine to ensure the healthy growth of the plant.

4. Timely harvest: when will the harvest be ready?

Dutch beans planted in June can be harvested in about two weeks. If planted in winter, they can be harvested in about a month. The specific harvest time is determined according to the planting time.

Generally speaking, the market price of Dutch beans is not expensive, usually about 3-7 yuan can buy a jin, but due to the difference in market, origin and time of sale, the price will be different, so try to go to the local market when buying. In addition, in order to achieve high yield of Dutch beans, it is necessary to do a good job in basic management such as water and fertilizer, loosening soil, picking heart and leaves and so on.
