Hello friends, in this video I want to talk about two problems in the process of growing tomatoes The first question is about soil requirements, the second question is about the problems that arise with the continuous planting of tomatoes First, tomatoes are more demanding on the soil. The pH level is between 6 and 7, which corresponds to slightly acidic or neutral soil How to determine the nature of the soil, I invite farmers to watch my previous video I specifically talked about how to determine the pH of the soil and how to improve it. Everyone knows that if we use the same fertilizer constantly Moss will appear regularly on the ground This is the permanent cultivation of the soil The harm caused by this is that the roots of plants have a particularly large number of root knotty nematodes. Secondly, seedlings of agricultural crops die easily In response to this problem, we have always advocated using summer to heat the soil. High temperature and stuffy shed from a month to a month and a half But after years of planting tomatoes, the effect of the stuffy barn is no longer obvious. Some commonly used methods are using lime nitrogen That is, use calcium hydroxide to prevent this disease Root knotty nematodes, at the same time when we transplant Thiazophos or abamectin is recommended To prevent the appearance of root node nematodes Farmers are encouraged to use microorganisms at the same time If the amount of the main fertilizer is relatively large, it is recommended to use some microorganisms before expanding the fruit Microorganisms are usually injected every 15 days It is recommended to use one to two liters of microbes per mu of soil before expanding the fruit. Can mainly reduce these crop diseases In addition to the above, I also suggest that farmers use it in combination with a stuffy barn
