Description

Welsh onion growth slow-release BB fertilizer

Technical Field

The invention relates to a slow-release BB fertilizer for growth of red onions, and belongs to the technical field of production of red onion fertilizers.

Background

The red scallion is a cultivation variety of the scallion, has mellow fragrance and better quality, is deeply favored by consumers, is a good name of 'the country of the red scallion' in the river height dewatering center village of the white cloud area in Guangzhou city, is a high-efficiency and high-quality red scallion production base in the city, has smooth market sale, good economic benefit and obvious industrial advantages. By adopting the fertilizer which is sold conventionally in the market, the problem of soil acidification is not solved, the yield of the red onions is improved, the fertilizer usage amount is large, the price is high, and the burden of farmers is increased. Meanwhile, urea is easy to volatilize and lose, most nutrients are lost, and the nutrients required in the quick growth of the red onions can be supplemented only by applying fertilizers for many times, so that the labor cost is increased.

At present, through search, the existing data relate to reports on the aspects of special fertilizers for scallion, such as: the Chinese invention patent 201510149799.5 discloses a special fertilizer for scallion and a preparation method thereof, and the method discloses a special fertilizer for scallion and a preparation method thereof, wherein the special fertilizer consists of an organic fertilizer and an inorganic fertilizer, and the organic fertilizer is prepared from the following raw materials in parts by weight: 40-65 parts of livestock manure, 10-30 parts of peanut shell, 5-20 parts of bran, 5-20 parts of fresh garlic straw, 3-10 parts of fresh garlic bulb, 5-20 parts of waste Chinese medicine residue and 3-10 parts of traditional Chinese medicine components; 5-20 parts of fresh garlic straw, 3-10 parts of fresh garlic bulb, 5-20 parts of waste Chinese medicine residue and 3-10 parts of traditional Chinese medicine components; the waste Chinese medicinal residue is waste Chinese medicinal residue of Scutellariae radix, radix astragali, radix rehmanniae Preparata, radix Puerariae, and fructus Psoraleae; the traditional Chinese medicine components comprise arborvitae, ailanthus leaves, purslane, luffa stems, ailanthus leaves and pyrethrum; the inorganic fertilizer is a nitrogen fertilizer sold in the market. The fertilizer can greatly improve the yield of the green Chinese onions, reduce the occurrence of plant diseases and insect pests and has no drug residue. Plays an active role in improving the yield of the green Chinese onions and provides fertilizer source guarantee for the high yield of the green Chinese onions. However, few reports are reported about the special fertilizer for the red onions at present, and research and development of the special fertilizer for the red onions to promote the yield of the red onions have very important significance.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provide a slow-release BB fertilizer for growing red onions, aiming at improving the existing yield, effectively controlling the application amount of the fertilizer, reducing the fertilization times and reducing the overall production investment of the red onions.

In order to achieve the purpose, the invention adopts the technical scheme that:

the slow-release BB fertilizer for the growth of the red onions comprises the following components in percentage by mass:

43-50% of coated urea, 35-40% of potash fertilizer, 10-15% of organic fertilizer and 4-6% of medium element fertilizer;

the coated urea is prepared from urea, zeolite and a compound fertilizer binder, and the mass ratio of the components is as follows: 90% of urea, 3% -5% of zeolite and 5% -7% of compound fertilizer binder;

the compound fertilizer binder is prepared by mixing attapulgite and desulfurized gypsum in a weight ratio of 1: 1 in proportion;

the medium element fertilizer is prepared from 50-70% of calcium humate and 30-50% of magnesium sulfate.

The invention has the following advantages:

the slow-release BB fertilizer can be prepared by mixing according to a proper proportion according to the growth needs of the red onions, can be applied as a base fertilizer at one time, does not need additional fertilizer later, saves labor and time, has high utilization rate of coated urea, can reduce the loss of the urea, can quickly absorb ammonia generated by the decomposition of the urea by the roots of the red onions, and has simple preparation method and convenient operation. The slow release fertilizer has the following advantages:

1. the fertilizer consumption is reduced, and the utilization rate is improved. The fertilizer efficiency of the slow release fertilizer is longer than that of the slow release fertilizer without a coating for more than 30 days, leaching volatilization loss is reduced, the fertilizer consumption can be reduced by 10-20% compared with that of the conventional fertilizer, and the purpose of saving cost is achieved;

2. convenient application, labor saving and safety. The fertilizer can be matched with a quick-acting fertilizer to be used as a base fertilizer for one-time application, the labor for fertilization is reduced by about one third, and the fertilizer is safe to apply and prevents fertilizer damage;

3. increasing both production and income. After application, the fertilizer has stable and long effect, no falling off in later period, disease resistance and lodging resistance, and the yield is increased by more than 5%.
