Many farmers stubbornly believe that "good fertilizer is quick to take effect." This is a serious misunderstanding of fertilizer use. In fact, it is the opposite. Good fertilizer is not necessarily good fertilizer. Fertilizer needs to be supplied for a long period of time. The best method is to apply the fertilizer according to the physiological characteristics of the crops in various periods. Therefore, the author hereby reminds farmers: When buying fertilizer, you must choose rationally.
Generally speaking, the fertilizer validity period of fertilizer products is as follows:
(1) Ammonium bicarbonate: effective on the same day, fertilizer effectiveness period is 15 days; (2) Ammonium chloride: effective in three days, fertilizer effectiveness period is 25 days, later defertilization; (3) Urea: effective in seven days, fertilizer effectiveness period is 45 days; (4) Compound fertilizer: effective in ten days, fertilizer effect period is 90 days; (5) Biological fertilizer: generally effective in about one month, the effect is not obvious on crops with long growth cycle, but the fertilizer effect can last for 6 to 8 months; (6) Hormones: It takes effect quickly, but it doesn't have much nutrition, and it doesn't help much to increase production.
In order to cater to the "quick results" mentality of vegetable farmers, many unscrupulous manufacturers add excessive amounts of hormones in fertilization to reduce the content of nutrients such as nitrogen, phosphorus, and potassium. This hormone fertilizer can be effective for 1 to 2 days after flushing, and the surface effect is very obvious, but after continuous use for 2 to 3 times, you will find that the bottom leaves of the plant are yellow, the stems are thin and the fruit grows poorly. The normal growth period of vegetables and the severely shortened fruit picking period are the consequences of the abuse of hormones.
The growth of crops is regular, and the roots are deep in order to have luxuriant leaves. Rooting in the early stage, long stalks in the middle stage, and fruiting in the late stage. No matter how vigorous the leaves are, it is only an appearance, and the result will only lead to premature aging and death of crops. What we pursue is yield and quality, not stems and leaves.
Therefore, when we choose fertilizers, we cannot judge the quality of a product solely based on its growth. We must understand that the ultimate goal is yield and quality. Fertilizers that can increase production and ensure quality are good fertilizers.
