Huge water retention nutrition pot as well as preparation method and application thereof

Abstract

The invention discloses a huge water retention nutrition pot. The huge water retention nutrition pot is prepared by using the following components in weight percent: 35-40 percent of water retention material, 30-35 percent of raising agent, 25-30 percent of vermiculite, 1-3 percent of urea, 1-3 percent of diammonium phosphate, and a method for preparing the huge water retention nutrition pot and an application of the huge water retention nutrition pot in planting of seedlings in sandy soil are provided. The huge water retention nutrition pot as well as the preparation method and application thereof have the advantages that the nutrition pot for planting of seedlings in sandy soil and similar soil in northwest areas is capable of effectively overcoming the defects of poor water retention capacity of sandy soil and poor nutrition, and provides a good soil environment for the growth of seedlings; when the huge water retention nutrition pot is used for planting of seedlings in sandy soil, the survival rate of seedlings in the same year is improved by 70-80 percent above, the survival rate in the next year is improved by 60-70 percent, the annual young shoot growth is increased by 17-18 percent, the diameter of the main stem is increased by 19-20 percent, and the total biomass is increased by 17-21 percent.

Description

technical field [0001] The invention relates to the field of sandy soil planting, in particular to a giant water-retaining nutritional pot and its preparation method and application. Background technique [0002] The soil in Northwest China is barren, soil erosion is serious, climate is arid, windy and sandy, and soil desertification is obvious. These factors seriously affect the vegetation status in Northwest China. How to protect the existing vegetation, green the degraded vegetation, and plant seedlings on the sandy soil is a major research topic. The key to solving this problem is how to improve the nutrient level and water retention capacity of desertified soil. [0003] With the development of social economy, urban sewage treatment plants are becoming more and more popular, and the amount of sludge produced is increasing continuously. The way out of sludge has become a major research topic. Because the sludge is rich in organic matter (organic matter content exceeds ...
