The maximum efficiency period of vegetable crop nutrition

In the process of crop growth, there is a period in which the absolute amount of nutrients needed is the largest, the absorption rate is the fastest, and the absorbed nutrients can maximize the efficiency of increasing production. This period is called the maximum efficiency period of crop nutrition.

The maximum efficiency period of crop nutrition is generally in the middle of crop growth, during this period, crops grow fast and have the strongest ability to absorb nutrients. Timely topdressing is used to meet the maximum nutrient needs of crops, and its yield-increasing efficiency is very significant.

In the cultivation of vegetable crops, they should be divided into two categories according to the law of fertilizer demand of different vegetable crops; one is that the absorption of mineral nutrients increases with the growth of vegetable crops, such as Solanaceae, melons and legumes, which need the most fertilizer during fruit formation. About 50% of the nutrients absorbed are used in fruits. The other type is mainly root vegetables and potatoes and other vegetables, the upper part of the local vigorous growth period is the period to absorb the most nutrients.

In the process of vegetable crop growth, attention should be paid to nutrition critical period and maximum efficiency period, but attention should also be paid to the continuity of nutrient absorption, which will affect the growth, development and yield of vegetable crops.
