Problems solved by technology

Among them, open-field seedling cultivation is relatively extensive and difficult to manage, and soil-borne diseases are difficult to control. The amount of seeds used is large, and the seedlings are of different sizes, which is labor-intensive. In the process of seedling cultivation in plug trays, the seedlings are isolated from each oth

Example Embodiment

[0013] Example 1

[0014] A nutrient solution for growing cabbage seedlings. Each liter of solution contains the following components by weight: potassium nitrate 190mg, ammonium sulfate 160mg, potassium hydrogen phosphate 100mg, magnesium sulfate heptahydrate 310mg, chelated iron 20, the balance For water.

[0015] When preparing the nutrient solution, measure the components in the above ratio, first add water to the vessel, and then add potassium nitrate, potassium hydrogen phosphate, magnesium sulfate heptahydrate and chelated iron to the water in sequence. After the dissolution is complete, measure the liquid pH value: Next, drop the ammonium sulfate solution into the liquid, and stir while dripping. Finally, the pH value of the nutrient solution is measured to be 5.5.

Example Embodiment

[0016] Example 2

[0017] A nutrient solution for growing cabbage seedlings. Each liter of solution contains the following components by weight: 200mg potassium nitrate, 150mg ammonium sulfate, 120mg potassium hydrogen phosphate, 320mg magnesium sulfate heptahydrate, 25mg chelated iron, and the balance For water.

[0018] When preparing the nutrient solution, measure the components in the above ratio, first add water to the vessel, and then add potassium nitrate, potassium hydrogen phosphate, magnesium sulfate heptahydrate and chelated iron to the water in sequence. After the dissolution is complete, measure the liquid pH value; secondly, drop ammonium sulfate solution into the liquid, stir while dropping, and finally measure the pH value of the nutrient solution to 6.

Abstract

The invention discloses nutrient solution for cabbage seedling cultivation. The nutrient solution is characterized in that per liter of the solution contains 190-220mg of potassium nitrate, 140-160mg of ammonium sulfate, 100-120mg of potassium hydrogen phosphate, 300-320mg of magnesium sulfate heptahydrate, 20-25mg of chelated iron and the balance water, and a pH value of the nutrient solution is kept in a range of 5.5-6.5. The nutrient solution which is applied to a cabbage plug seedling cultivation process is capable of providing sufficient nutrients for seedlings to make the seedlings developed in root system and robust in plant, so that thriving of the seedlings can be guaranteed, and the seedling survival rate is increased. The nutrient solution is especially suitable for water high in salt and alkali content.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to a method for producing cabbage seeds. Background technique [0002] Cabbage is one of the main vegetable varieties in my country. With the increase of planting area year by year, it has become one of the main economic incomes of vegetable farmers. During the cabbage planting process, seeds are sown by planting cabbage seeds, so in the cultivation process of cabbage seeds, it is necessary to ensure the quality of the cabbage seeds. The preparation of cabbage seeds needs to be obtained after a series of processes such as seedling cultivation, seedling transplanting, overwintering management, seed planting in the next spring, cross-pollination, harvesting pods, and threshing. [0003] There are two kinds of existing cabbage seedling raising methods, one is growing seedlings in the open field, and the other is growing seedlings in plug trays. Among them, open-field ...
