How and when to grow beans

Planting time of eyebrow bean: open field planting is generally carried out in summer, in the Yangtze River Basin from May to July, and in North China in June. Site selection: warm areas rich in humus should be selected for planting. Soil preparation and sowing: first remove weeds, then plough the soil and apply rotten farm fertilizer, with a small amount of chemical fertilizer, rake flat, you can take direct seeding, hole sowing, ditching and other ways of sowing. Late management: a small amount of watering in the seedling stage, watering every 10 days or so in the flowering and pod stage, setting up a frame before pulling the vine, pruning and picking the heart in time.

1. Planting time of eyebrow beans

Eyebrow beans are usually planted in the open field in summer and can be harvested and listed in mid-January. the climate will be different in different regions, and the sowing time will be different. For example, the Yangtze River basin will be planted in May-July. North China will probably be planted in June.

II. Site selection and seed selection

The main results are as follows: 1. Before sowing, the areas with moderate light, rich humus and warm climate should be selected for planting, which is beneficial to better plant growth and increase yield.

2. There are many varieties of eyebrow beans, which are green eyebrow beans, white eyebrow beans and purple eyebrow beans according to the pod color. In addition, the green eyebrow beans are relatively thin, crisp and tender, and the pods of white and purple eyebrow beans are thicker and softer after cooking.

3. Soil preparation and sowing

1. After selecting the planting site, you need to remove weeds from the soil, and then combine ploughing with about 3000 kilograms of rotten farm manure per mu, apply it with a small amount of chemical fertilizer, and rake it flat, so that the soil and fertilizer can be mixed evenly.

2. Eyebrow beans are usually planted by direct seeding, or by trenching or hole sowing. The spacing between plants is about 30-50cm, the spacing between rows is about 100-130cm, and about 3-4 seeds can be sown in each hole. After emergence, only two plants can be left in each hole.

IV. Post-management

The main results are as follows: 1. Meidou is more drought-tolerant, can be watered in a small amount at seedling stage, can be watered about 1-2 times in vine extension period, and can be watered every 10 days at flowering and pod stage.

2. After watering, eyebrow beans must be properly ploughed and weeded, combined with fertilization to prevent plant overgrowth, flower and fruit drop, apply a small amount of thin fertilizer before flowering, and can be re-applied in podding period after flowering, and must be reasonably matched with the amount of nitrogen, phosphorus and potassium fertilizer when fertilizing.

3. The plant must set up a frame before pulling the vine, and let the stem slowly climb onto the hedge. When the main vine grows to about 1.5m, it can begin to prune and pick the heart, which is beneficial to promote the lateral branches to grow, thus blossom and bear pods early.

V. Prevention and control of diseases and insect pests

The main diseases and insect pests of Mei bean are aphids and bean pod borer. Imidacloprid and acetamiprid can be used to control aphids. Attention must be paid to the concentration of imidacloprid and acetamiprid. 2500 times of fenpropathrin or 1000 times of 50% fenitrothion can be sprayed on its leaves, and can be changed once a week to avoid drug resistance.
