Cherry tomato culture medium and preparation method thereof

Abstract

The invention discloses a cherry tomato culture medium and its preparation method. The cherry tomato culture medium comprises the following substances (by weight): 65-80 parts of crop straw powder, 30-45 parts of soybean meal, 15-26 parts of peanut meal, 15-20 parts of spent mushroom compost powder, 14-20 parts of humic acid, 13-20 parts of algae powder, 20-26 parts of plant ash, 15-21 parts of fishbone dust, 13-18 parts of Styphnolobium japonicum wood dust, 9-16 parts of pine needle meal, 25-35 parts of poultry manure, 20-35 parts of peat soil and 10-16 parts of coal ash. The invention also provides a preparation method of the cherry tomato culture medium. The prepared culture medium is specifically a culture medium for growth of cherry tomato. Straw used for the prepared culture medium is rich in nitrogen, phosphor, potassium, calcium, magnesium and organic matters, etc. The culture medium produced by fermentation of natural raw materials meets crop growth and development requirements, has more excellent fertility than a fertilizer purchased in the market, is easier to absorb and has fast release speed of fertility. The prepared culture medium can be used to remarkably raise quality and yield of cherry tomato.

Description

technical field [0001] The invention relates to a cherry tomato cultivation substrate and a preparation method thereof. Background technique [0002] Although the research and extension of soilless cultivation in our country only emerged in the middle and late 1980s, it has developed rapidly. According to incomplete statistics, the national soilless cultivation area has exceeded 200hm2. my country's research and promotion is mainly nutrient solution soilless cultivation, all of which are irrigated with nutrient solution prepared by chemical fertilizers. In terms of nutrient solution management and root oxygen supply, the technical requirements are high and the operation is difficult; and supporting auxiliary equipment such as cultivation tanks, timers, etc. , Water pumps and other input costs are expensive. These factors have seriously hindered the development of soilless cultivation in our country. Organic substrate soilless cultivation technology is a kind of high-effici...

[0004] Chinese invention patent CN103964958A (published on August 6, 2014) discloses a method for preparing organic substrates for cherry tomatoes, including fermentation treatment of organic matter, air drying, crushing treatment, screening, cleaning and winnowing process and other steps , the total nitrogen content of the prepared organic matrix is ​​8-12%, the carbon content is 65-72%, the total sugar content is 8-12%, the reducing sugar content is 5-9%, the nicotine content is 1-1.8%, and the humic acid content 7-12%, the organic matrix made by this invention can greatly increase the yield of cherry tomatoes, improve the quality, and can effectively reduce the occurrence of diseases, but this invention has no good effect on reducing the rot rate of cherry tomatoes in post-harvest storage

At present, there are relatively few reports and studies on the cultivation medium that can improve the quality and yield of cherry tomato
