Green beans, also known as green beans, are one of the main varieties of frozen frozen bean vegetables exported from China. China is suitable for multi-season production of green beans, mainly divided into spring and autumn seasons. The green beans can be cultivated in large quantities and exported to surrounding big cities. It is one of the main vegetable varieties for urban residents. Spring beans are mainly cultivated in greenhouses. The following microbiological fertilizer expert, Jinbao, will arrange for the vegetable farmers how to grow good green beans at a lower price in the spring.
1. Preparation of Spring Planting Fertilizer for Green Beans
Fertilizer plays an important role in both traditional agriculture and modern agriculture. Fertilizers include topdressing and base fertilizers, and the use of topdressing fertilizers is small, and the phenomenon of uneven use tends to occur. The use of base fertilizers is large, and organic fertilizers are more expensive. For the base fertilizer, the organic fertilizer is the most important. With the development of science and technology, the basic fertilizer will eventually get rid of the traditional way of farmyard manure. In addition to poor fertility, natural organic fertilizers also have secondary fermentation. Secondary fermentation of organic fertilizers will burn seedlings and affect crop growth. Therefore, the mature organic fertilizer starter needs to be completed by some organic fertilizer starter such as a goldfish organic fertilizer starter. Organic fertilizers have a wide range of sources, such as human and animal excreta, and household waste (such as rotten leaves, poultry, chicken bones, meat waste, etc.). Fermentation Fermentation Fertilizers are also cheaper to use: For example, the use of Fertilizer Fermentation Fertilizer Fermentation Fertilizers can be completed using 1 kg of Trichoderma Fertilizer for every 2 tonnes of waste. The fermentation process is simple and easy to operate, the fermentation time is short, and the fertilizer can be fermented after 7-10 days.

2. Spring bean sowing and colonization
In early spring, seedlings are planted in plastic greenhouses, and cultivated flowers and buds are sprayed in spring and autumn. Live streaming. Choose fresh seeds that are full, free from pests, and have shiny seed coats. Before sowing, look for sunny days for sowing, or formalin soaking with water to sow seeds. If the soil is dry, give enough water before planting. Generally, the width is 120cm wide and the depth is 30cm. Each row is 2 rows with 60cm spacing and 30cm spacing. Sowing 3 seeds per hole, cover fine soil 2 cm after sowing. After the emergence of the seedlings, 1 seedling was transplanted, and 3-4 seedlings were planted in each hole.
3. Spring cultivating, weeding and fertilizing of green beans
About 10 days after sowing, the first shallow plough weeding was conducted after Qi Miao. 7-8 kg of compound fertilizer was applied per mu. Fertilizer can not be too close to the seedlings, so as not to cause burning seedlings rot and so on. The first 2 cultivators were planted before the vines were planted, and the soil was planted on the base of the plant stems in combination with clear ditches and the compound fertilizer was applied per mu. After entering the end of the pod period, the green beans will be poured without watering. Generally combined with sitting water, per acre topdressing compound fertilizer 10 kg. In the crusting stage, potassium dihydrogen phosphate and borax liquid sprayed on the leaves should also be used twice to increase the yield.
4. Spring beans planted in spring
The bean sticks should be picked up early. When the vines are about 15 centimeters long, they will use long racks to take down the “person†shape frame. In each row of intersections, a rack is placed as a crossbar, tightly tied with a string, and twisted in a counterclockwise direction.
5. Spring bean planting pest control
Four-season beans grow fast, and they can generally be harvested about 10 days after flowering. Adhere to 1 time a day, at the same time to do a good graded packaging! In order to improve the commercial and economic benefits of green beans. After clearing the garden, the pods should be removed in time and the deciduous leaves should be removed and burned in a concentrated manner. This can effectively reduce the incidence of diseases and insect pests in summer.
