Tomato planting technology: It is very important to control the soil salinization
Soil salinization is an important factor hindering the high yield of tomato, so controlling soil salinization is critical. So how to prevent soil salinization, we must first identify which situation is the performance of soil salinization. I went to the countryside two days ago. A farmer took me to his greenhouse to see that the farmhouse has been planted for nearly six years and is a typical old shed. According to the fellow, the tomato disease planted in these two years is particularly serious, and the fertilizer is not used much. The output is always up, and a tomato can be 6 kg high. Into the shed of the fellow, although psychological preparation, but the scene is still scared, the head of the tomato has been harvested, bare soil, looking into the distance, full of red. The villagers reflected that the tomato production was low in the past few years, and the disease was serious. It was caused by the dense planting of the soil and belonged to the typical soil salinization. The main reason for the occurrence of soil salinization is related to the large use of chemical fertilizer by growers. We all know that chemical fertilizer is an inorganic salt and is composed of salt ions. To give a simple example, planting tomato supplemented with potassium fertilizer is inseparable from potassium sulfate fertilizer. Potassium sulfate is decomposed into sulfate and potassium ions in the soil so that potassium ions can be absorbed by the crop. However, sulfate ions cannot be absorbed by crops and only remain in the soil, which leads to an increase in soil salinity, and even it combines with metal ions to affect the absorption of trace elements. First, how to distinguish soil salinization 1. The soil in the greenhouse is planted with tomato. After a few days of pouring water, there will be a layer of green moss. Some tomato growers call it green frost. This is the performance of mild salinization. 2. When the tomato is planted in the greenhouse, after the soil is planted, the surface will appear like a layer of red. In some places, the growers call it red frost, which is a serious salinization. 3. When the tomato is planted on the ground of the greenhouse, after the soil has dried up, a layer of “white frost†will appear, which indicates that soil salinization has been particularly serious. Second, soil salinization control measures 1. The grower should re-apply organic fertilizer, do not use animal manure crop organic fertilizer, and the salt content in it is relatively high. It can be improved by using the organic fertilizer after straw fermentation. 2, re-application of microbial agents, the use of biological bacteria to accelerate the decomposition of soil salinity, improve the soil, the two methods combined best results.
