Seedling promoter specially used for cotton substrate seedling culture

Abstract

The invention relates to a seedling promoter specially used for cotton substrate seedling culture. The seedling promoter comprises the following components by weight percent: 1.0-1.5% of an antitranspirant, 32-42% of sucrose, 56-66.5% of nutrient materials and 0.2-0.5% of a conditioning agent. The seedling promoter is capable of effectively promoting the growth of the root systems and overground parts of cotton seedlings, and shortening recover period after cultivation.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a seedling-strengthening agent specially used for raising seedlings with cotton substrates. Background technique [0002] Cotton is an important economic crop in my country. At present, cotton in the southern cotton region of my country is mainly planted in the method of transplanting seedlings in nutritional pots. This seedling raising method needs to prepare cylindrical nutritional pots with a diameter of about 7cm and a height of 8-10cm. The situation of the transfer of young labor force to the city. Cotton matrix seedling raising technology has become a light and simple seedling raising technology widely used in production because it does not need to make nutrient pots, which significantly saves seedling raising and transplanting labor and production materials input. [0003] The plastic plug used in the cotton matrix seedling raising technology is an or...

AI Technical Summary

Problems solved by technology

[0003] The plastic plug used in the cotton matrix seedling raising technology is an ordinary plastic plug with only a small hole (about 0.5 cm in diameter) at the bottom. The hole exchanges water and nutrients with the surrounding area, which cannot meet the needs of seedling emergence and cotton seedling growth, resulting in the need for frequent water and nutrient supplementation after seedling emergence to achieve cotton seedling growth

Due to the small holes in the seedling tray, the ability to retain water and fertilizer is poor, frequent replenishment of water and nutrients takes a lot of work, and the management of water and nutrients is not in place or used excessively, it will also form weak or vigorous seedlings, resulting in light cotton seedling production It is common for plants to live slowly after planting, late blooming and late maturity, etc., and the yield is not high, which affects the industrialization and marketization of substrate seedling raising technology.
