Driven by the requirements of large-scale planting and the laws of market prices, today's vegetable growers often have what kind of varieties to earn money on. What's more, the higher the price of vegetables, the more they are willing to fertilize, and the phenomenon of over-fertilization and planting varieties is common. In the long term, the output of vegetables has dropped drastically and the economic benefits have decreased. The main reason for its production is the soil salinization in the vegetable field, and the PH value is too high or too low.
Causes of "aging" in vegetable fields
Continuous vegetables of the same kind
One year after another, the cultivation of the same kind of vegetables in the same section caused excessive accumulation of harmful substances in the roots, resulting in poor growth. A large number of pathogens that are susceptible to the same type of vegetables are accumulated, and the microbial population is dissociated, which relieves the mutual inhibition between the bacterial flora and the bacterial flora, which is not conducive to the ripening of soil and the decomposition and differentiation of fertilizer nutrition. Continuous cropping also causes a lack of certain elements of the same type of vegetables.
The soil concentration barrier is generally about 2000 mg/kg in the first year of vegetable field soil, and will increase year after year. As a result, green skin is produced on the surface of the soil, and the roots of the crop are soaked in the pickle pond that the growth range becomes smaller. The antagonism between the nutrient elements and the ions causes the fertilization to be ineffective, causing people to mistakenly believe that it is the lack of fertilizer and increasing the amount of fertilization. As a result, the plant appears reverse osmosis and shrivels.
Prevention and resolution
In the arrangement of varieties, the rotation of crops should be the main planted variety with the best market value and output value, and the other varieties with better integrated benefits should be selected the rest of the time.
Use hole fertilizer
Farmers generally apply the fertilizing method. This method not only wastes fertilizer, but also does not work well. Roots should be fertilized at a depth of 2 to 3 cm in the vegetable roots, which can induce deep rooting and reduce the contact area between the fertilizer and the soil, and prevent phosphorus, calcium, and other elements from losing their activity due to soil fixation. At the same time, acupuncture points fertilize the vegetable roots with respect to soil concentration; avoidance and choice to maintain its vigorous growth.
Formula fertilization should be increased organic fertilizer, less fertilizer, to prevent over-application of a single fertilizer or a single species, and the use of humic acid vegetable multi-element special fertilizer timely addition of trace elements. Nitrogen fertilizers are preferably ammonium nitrate, preferably not using urea. Because urea needs to be transformed within 7 to 30 days, it is absorbed by plants, and it is lost in the conversion process, which can easily cause ammonia poisoning in the leaves and roots of vegetables.
Application of Soil Active Fertilizers Humic Acid Organic fertilizer is organically active humic acid. It not only releases phosphorus and potassium, loosens the soil, increases the number and length of roots, but also sterilizes, stimulates crop growth, and supplements and decomposes soil nutrients.
