Azalea culture medium prepared from cotton stalks and preparation method of azalea culture medium

Abstract

The invention relates to an azalea culture medium prepared from cotton stalks. The azalea culture medium comprises the following raw materials in a volume ratio: 10 parts of decayed cotton stalks, 4-5 parts of roseite powder, 1-2 parts of sand, 2-3 parts of modified plant ash and 5-6 parts of turf. A preparation method of the modified plant ash comprises the following steps: adding nanometer attapulgite which is 2wt%-3wt% of plant ash, 1wt%-2wt% of calcium lignosulphonate, 1wt%-2wt% of urea, 0.8wt%-1.5wt% of sodium carboxymethyl cellulose, 3wt%-4wt% of shikakai powder, 8wt%-10wt% of starch and proper water in the plant ash, sufficiently stirring for 1-2 hours at the rotate speed of 800-900 rpm, and pelletizing until the grain size is 4-5 mm. The culture medium disclosed by the invention is capable of improving the physicochemical property of an original single medium, and the components are easily available and are low in cost. When the culture medium disclosed by the invention is applied to the soilless culture of azalea, flower seedlings can grow fast, branches and leaves grow well, the overall flowering rate is as high as about 75%, and the diameter of flowers can be as large as more than 70mm.

Description

technical field [0001] The invention relates to traditional Chinese medicine cultivation technology, in particular to an azalea cultivation substrate prepared from cotton stalks and a preparation method thereof. Background technique [0002] Cotton is an important economic crop in our country. In cotton-producing areas, a large number of cotton stalks will be left after picking cotton every year. Usually, these cotton stalks are used as firewood to burn, resulting in a waste of resources. The value of cotton stalks has not been well used. Therefore How to improve the utilization value of cotton stalks has become an urgent need for cotton farmers. [0003] The value of plant ash has long been recognized by people. The most used situation is to add it directly to the farmland as a fertilizer. However, due to the scattering of plant ash, it will cause waste and bring environmental pollution when it is used in strong winds. . [0004] The soilless cultivation base of the prese...
