Planting techniques of green beans in greenhouse

I. Variety selection

Early-maturing, high-quality and high-yield varieties should be selected, the main varieties are: purple flower oil bean, peanut oil bean, Harai bean No. 1.

2. Raising seedlings

The seedlings were raised in a nutrient bowl in the greenhouse. The sowing time is generally in the early and middle of March in the southern region and in the middle and late March in the northern region. The standard of strong seedling, the strong seedling with good exercise, the plant clump is short and strong, the root system is well developed, 2 Mel 3 true leaves, the seedling age is 30 mi 35 days.

III. Colonization

It is usually planted in the first and middle of April. The thermal insulation measures during planting: the internal thermal insulation adopts the small greenhouse in the greenhouse, the double-layer curtain is hung, and the warm air stove in the shed is used if necessary, and the external thermal insulation is mainly covered with grass mulch around the shed.

IV. Field management

Keep 20-25 ℃ during the day and 15 ℃ at night, and enter the flowering period at about 20 ℃ during the day and more than 15 ℃ at night to facilitate normal flowering and pod bearing. In terms of water management, because kidney beans have a certain ability of drought tolerance, there is generally no irrigation and fertilization from planting to flowering to prevent excessive growth of stems and leaves. At the beginning of flowering, it is necessary to increase the amount of air release and remove moist air so as to facilitate pollination, avoid falling flowers and reduce diseases.

V. Harvest and listing

Kidney beans are tender pods for consumption. When the pods reach commercial maturity, they should be harvested at the right time. In general, the dwarf species began to be harvested 25-35 days after planting, and the vine species began to be harvested at 35: 45 days after planting, once every 5 days, and once every 2 days at the peak podding period. Late harvest affects the quality and the pod setting of subsequent inflorescences. The pods harvested should be put on the market in time, and those not on the market can be kept fresh in the environment of 3 ℃.
