Selenium-rich base fertilizer for planting kale

Abstract

The invention discloses a selenium-rich base fertilizer for planting kale, and relates to the technical field of planting. The selenium-rich base fertilizer is prepared from, by weight, 100-120 parts of selenium-rich crop straw, 30-40 parts of melon vines, 15-20 parts of pennisetum sinese roxb, 15-20 parts of bagasse, 13-17 parts of soyabean bran, 10-15 parts of palm oil, 8-13 parts of modified zeolite powder, 6-10 parts of bentonite, 6-10 parts of tomatoes, 5-8 parts of traditional Chinese medicine residues, 4-7 parts of ground hydrated lime, 3-5 parts of bitter melon seed powder, 3-5 parts of nano zinc oxide, 2-3 parts of realgar, 1-2 parts of polyacrylamide and 1-2 parts of sodium polyacrylate. The prepared base fertilizer is loose and rich, the oil hardening phenomenon does not occur after the base fertilizer is used, and the requirements of growth of the kale on nutrition can be fully met; organic selenium contained in the base fertilizer can be fully utilized by the kale, and therefore the selenium content of the kale is improved.

Description

Technical field:

[0001] The invention relates to the technical field of planting, in particular to a base fertilizer for planting selenium-enriched kale. Background technique:

[0002] Kale, a biennial herb, is a horticultural variety of cabbage. Its structure and shape are very similar to cabbage, except that the center of the kale is not rolled up. Cultivated for one year, the plants form rosette-shaped leaf clusters, and after the low temperature in winter, they will bloom and bear fruit in the following year. Kale is nutritious and contains a lot of vitamins A, C, B2 and various minerals, especially calcium, iron and potassium. Among them, the content of vitamin C is very high, and the content of vitamin C in every 100 grams of young leaves reaches 153.6-220 mg. It is comparable to broccoli in cabbage and is known as the best vegetable for the human body.

[0003] In recent years, with the improvement of living standards, people have higher and higher requirements for...
