Can the soil of the Yellow River Beach grow vegetables?

Vegetables can be grown in the soil of the Yellow River Beach. The soil of the Yellow River Beach? It belongs to sandy barren soil, and vegetables can be planted after improved scientific planting. The level of soil fertility and the intrinsic properties of soil are still very low, and the soil still needs effective fertilization to supplement it. How to scientifically fertilize the soil to increase crop yield?

First, the characteristics of sandy soil in agricultural production

Sandy soil has many characteristics in agricultural production because of its high sand content, large number of macropores between soil particles, poor water and fertilizer conservation performance and fast heat absorption.

1, well ventilated and convenient for breeding. Because of the good permeability of sand, it is not easy to be waterlogged; Small breeding resistance, convenient breeding and low energy consumption; The quality of long-term cultivation in suitable farming period is good, and clods and clods are not easy to form. As long as the soil moisture and soil temperature are suitable, it is generally easy to germinate early and produce good seedlings.

2. Low nutrient content and poor fertilizer conservation. The content of sand particles in sandy soil is absolutely dominant, and sand particles absorb less nutrients, so this kind of soil is very easy to lack some nutrients. Because there are many gaps between sand grains in sandy soil, organic matter decomposes quickly, which is not conducive to the accumulation of soil organic matter. Therefore, sandy soil generally lacks organic matter, has low nutrient content, and has poor water and fertilizer conservation ability, especially improper irrigation and chemical fertilizer application, which is prone to water leakage and fertilizer leakage.

3. The soil temperature changes rapidly and the temperature difference is large. There is often less water and more gas in the soil, and the surface soil temperature rises rapidly during the day, but it is easy to dissipate heat and cool down at night, so the temperature difference between day and night is large. This is beneficial to the growth of root and tuber crops and the accumulation of carbohydrates. The soil temperature rises rapidly in early spring, which is beneficial to the greening of winter wheat and the growth of crops such as cotton and peanuts. However, the soil temperature drops rapidly in late autumn, which is unfavorable to the growth of overwintering crops.

4, it is easy to premature aging in the later stage. Early senescence is easy to occur in the later period of crop growth, which leads to crop yield reduction. Therefore, sandy soil has the saying that "the seedlings are not old".

Second, the principle of sand fertilization

According to the characteristics of agricultural production of sandy soil, combined with the actual production in mengzhou city, in order to make better use of sandy soil, the principles of fertilization mainly include:

1, increase the application of organic fertilizer to improve the content of soil organic matter.

2. It is advisable to use cold manure such as cow dung or semi-mature organic manure as base fertilizer to improve soil water storage capacity.

3, topdressing should master the principle of "small amount and multiple times", reduce nutrient loss and improve fertilizer utilization rate.

4. In the later period of crop growth, nitrogen fertilizer must be applied in time to prevent premature senescence of crops. (fertilization)
