Problems solved by technology

[0003] At present, the development of my country's vegetable seedling industry is not very mature, and the quality of vegetable seedlings is uneven, and the quality of vegetable seedlings not only affects the cultivation and management of vegetable plants in the middle and late stages, but also affects the market period of vegetables and the entire vegetable industry. Quality, so that the "production, supply and marketing" of vegetables has been affected to a large extent, seriously restricting the development of the vegetable industry to scale and intensification

Abstract

The invention discloses an industrialized seedling raising nutrient solution as well as a preparation method and application thereof. The effective ingredient of the industrialized seedling raising nutrient solution comprises the following components in parts by weight: 380-420 parts of potassium nitrate, 60-100 parts of potassium dihydrogen phosphate, 230-270 parts of magnesium sulfate, 880-920 parts of calcium nitrate, 0.006-0.01 part of boric acid, 0.004-0.008 part of copper sulfate, 0.14-0.20 part of ferric sodium ethylene diamine tetraacetate (EDTA), 0.01-0.03 part of manganese sulfate, 0.005-0.015 part of zinc sulfate, 0.0001-0.0003 part of sodium molybdate, and 300-350 parts of ethoxy-modified polytrisiloxane. The seedling raising nutrient solution is used in imported and domestic industrialized seedling raising matrix in coordination with use methods of spring and autumn seedling raising, and can provide full-valance nutrient elements required by seedling stage growth, guarantee uniform seedling and strong roots and strong stem leaves, relieve diseases and insect pest and enhance stress resistance; and by using the seedling raising nutrient solution, the percentage of fertile fruit after field planting is high and the yield is improved.

Description

technical field [0001] The invention relates to a professional nutrient solution for plant growth in industrial seedling production. In particular, it relates to an industrial seedling raising nutrient solution and a preparation method and application thereof. Background technique [0002] Factory seedling raising is a mature advanced agricultural technology that has emerged with the rapid development of modern agriculture, agricultural scale management, specialized production, mechanization and automation, and is an important part of factory agriculture. It is an advanced production method to mass-produce high-quality seedlings under the best environmental conditions created artificially, using scientific, mechanized, and automated technical measures and means. Compared with the traditional seedling raising method, industrial seedling raising technology has the advantages of using less seeds and occupying a small area; it can shorten the seedling age and save seedling rais...
