The latest course of fertilization techniques and methods for beans

Bean is one of the popular vegetables widely cultivated in China, which is planted all over the country. it has strong adaptability, can be cultivated in open field, can grow all year round, and is listed all the year round. But when planting beans, master fertilization technology, related to its yield, then how to fertilize beans, Xiaobian summarized for everyone, let's take a look at the detailed introduction.

1. Characteristics of fertilizer requirement

The root system of bean is developed, but its root regeneration ability is weak, generally, the main root is about 1 meter into the soil, the lateral root is less, and the group root is partly in the soil layer of about 15 cm. Its root nodule is less, so the ability of nitrogen fixation is not strong, so it is suitable to be planted in the soil with loose fertility, good drainage and good air permeability, but not in the sticky soil. Its demand for fertilizer is not high, in the early stage of growth, the ability of nitrogen fixation is weak, so it is necessary to properly supply nitrogen fertilizer; after flowering and pod, the demand for phosphorus and potassium fertilizer surges sharply, and the nitrogen fixation capacity is enhanced, and the vegetative growth and reproductive growth go hand in hand. The demand for other nutrient elements is increased. According to research, for every 100 kilograms of production, we need to consume 1.02 kilograms of nitrogen, 0.44 kilograms of phosphorus pentoxide and 0.97 kilograms of potassium oxide.

2. Heavy application of base fertilizer

According to the fertilizer characteristics of beans, it is necessary to apply fertilizer scientifically, and continuous cropping is avoided, so it is best to choose plots that have been planted with cotton and legume crops within three years. First of all, it is necessary to apply base fertilizer, which is mainly based on rotten organic fertilizer, with an appropriate proportion of compound fertilizer, such as high phosphorus and potassium compound fertilizer is more suitable for beans as base fertilizer. It should be noted that when applying base fertilizer, it is necessary to increase or decrease the amount of fertilizer reasonably according to the fertility of the soil, so as to avoid fertilization management and lead to fertilizer damage to seedlings.

3. Skillfully applying topdressing

In addition to the application of base fertilizer, reasonable topdressing should be applied according to the growth status of beans in the growing period, mainly squatting seedlings after planting, to avoid excessive growth of stems and leaves, so as to promote the transformation of plants to reproductive growth and form more inflorescences. After podding, combined with watering, according to the mature organic fertilizer or compound fertilizer of 100 per mu, topdressing should also be done once after each harvest, with 5-10 kg of urea and 5-8 kg of potassium sulfate per mu. In order to avoid plant premature senescence in the later stage, after each yield peak, fertilizer and water management should be strengthened to promote lateral branch germination and flower bud formation.
