Organic fertilizer with water retention suitable for cucumber plantation, and its preparation method

Abstract

An organic fertilizer with water retention suitable for cucumber plantation is prepared by using the following raw materials, by weight, 10-12 parts of vermiculite gravel, 6-8 parts of cucumber stem, 7-9 parts of shell powder, 3-5 parts of carragheenan powder, 5-7 parts of starch, 14-17 parts of poultry manure, 12-14 parts of rice bran, 15-18 parts of clay, 2-3 parts of EM bacterial strain, 5-7 parts of potassium humate, 6-8 parts of monoammonium phosphate, 10-14 parts of potassium nitrate, 3-4 parts of pimacol, 8-10 parts of copper sulfate pentahydrate, 5-6 parts of an assistant and a proper amount of water. The fertilizer is an organic fertilizer benefiting cucumber plantation. The key elements of cucumber plantation are abundant organic matters in soil, good water retention of soil and strong permeability. In the invention, carragheenan is cross-linked and compounded with various inorganic chemical components, organic matter fermentation is carried out to prepare the fertilizer, elastic colloids generated after the combination of the heated and dissolved carragheenan with chemical ions and cooling have adsorption and cross-linking characteristics, can effectively preserve nutrients and have a slow release effect, the especially added vermiculite gravel can prevent soil hardening and increase the ventilation and the water supply of cucumber roots, and various biological factors are produced after fermenting the cucumber stem in organic matters are in favor of the cucumber growth according to biological natural substance cycle use.

Description

Technical field [0001] The invention is a water-retaining organic fertilizer suitable for cucumber planting and a preparation method thereof, and belongs to the technical field of cucumber planting fertilizer in fertilizers. Background technique [0002] Cucumbers like dampness but not waterlogging and fertilizer but are not tolerant to fertilizer. It is advisable to choose fertile soil rich in organic matter. Generally, soils with a pH between 5.5 and 7.2 are preferred, but the best pH is 6.5. [0003] Cucumbers have high yields and require large amounts of water. The suitable soil humidity is 60-90%. The seedling stage should not have too much water. The soil humidity is 60-70%. Sufficient water must be supplied during the fruiting stage. The soil humidity is 80-90%. The suitable relative humidity of the air for cucumber is 60-90%. If the relative humidity of the air is too high, it is easy to get sick and reduce production. [0004] The base for cultivating cucumbers should be ...
