Problems solved by technology

In order to prevent leek maggots and ensure production, some vegetable farmers often increase the amount of pesticides, increase the frequency of spraying, or use highly toxic pesticides, and even use highly toxic pesticides banned in some countries to control them, such as methamidophos and parathion etc., causing the leek pesticide residues to seriously exceed the standard

Embodiment 1

[0013] Test site: In-house scientific research base of Yantai Research Institute of China Agricultural University

[0014] Experimental scheme: The variety of leeks tested was Xinludiwang. The experimental design was two treatments, the control group and the test group, and the test group was applied with special bio-organic fertilizer for leeks. 28 parts of ammonium, 101 parts of potassium sulfate, 79 parts of kaolin, 1000 parts of biogas slurry, Bacillus megaterium greater than 1 million / g, Bacillus jelly-like greater than 5 million / g, Paenibacillus polymyxa greater than 10 million / g, fertilizer Total nutrients 12.2%. Apply 300kg of basal fertilizer per mu, and topdress 6 times in one growth cycle of leeks, and topdress 50kg each time. The control group was given urea, diammonium hydrogen phosphate and potassium sulfate with the same nutrient content as the experimental group. A randomized block experiment was adopted, with a plot area of ​​10m 2 , the yield was counted ...

Embodiment 2

[0019] Test location: Off-campus practice base of Yantai Research Institute of China Agricultural University

[0020] Experimental scheme: the variety of Chinese chives to be tested is Snow Chinese chives, and the experimental design includes two treatments, the control group and the experimental group, and the experimental group uses special bio-organic fertilizer for Chinese chives, and its formula is the same as that in Example 1. Apply 350kg of basal fertilizer per mu, topdress 6 times, and topdress 50kg each time. The control group was given urea, diammonium hydrogen phosphate and potassium sulfate with the same nutrient content as the experimental group.

[0021] Test results: The yield of leek per mu in the test group was 6124.3kg, which was 21.2% higher than that in the control group, and the incidence of diseases and insect pests was reduced by 51.4%. Example 3

Embodiment 3

[0022] Test location: Quhe Village, Jugezhuang Town, Muping District, Yantai City, Shandong Province

[0023] Test plan: the variety of leeks to be tested is snow leeks. The test design is two treatments, the control group and the test group. The test group is applied with special bio-organic fertilizers for leeks. The formula is as follows: 400 parts of decomposed dry biogas residue, 80 parts of peat, 80 parts of weathered coal, 60 parts of molasses, 70 parts of urea, 30 parts of diammonium hydrogen phosphate, 120 parts of potassium sulfate, 137 parts of kaolin, 800 parts of biogas slurry, not less than 1 million per gram of Bacillus megaterium, not less than 5 million of Bacillus jelly-like per gram, Paenibacillus polymyxa is not less than 10 million per gram, and the total nutrients of the fertilizer are 13.7%. Apply 400kg of basal fertilizer per mu, topdress 8 times, and topdress 50kg each time. The control group was given urea, diammonium hydrogen phosphate and potassium...

Abstract

The invention discloses a special biological organic fertilizer for Chinese chives and a preparation method thereof. The special biological organic fertilizer is composed of the following components in parts by mass: 400-500 parts of composted dry biogas residues, 80-120 parts of turf, 80-120 parts of decomposed coal, 40-60 parts of green syrup, 50-70 parts of urea, 20-30 parts of diammonium hydrogen phosphate, 80-120 parts of potassium sulfate, 51-137 parts of kaolin, 800-1200 parts of biogas slurry, no less than 1 million / gram of bacillus megatherium, no less than 5 millions / gram of bacillus mucilaginosus and no less than 10 millions / gram of paenibacillus polymyxa. The total nutrient content of the fertilizer is not less than 10%. The special biological organic fertilizer is applicable to the Chinese chives and is made from the biogas residues, the biogas slurry and functional microorganisms according to fertilizer needing requirements of the Chinese chives; the advantages of an organic fertilizer and a compound microorganism fertilizer are combined to improve the yield and the quality of crops; soil-borne diseases are inhibited.

Description

technical field [0001] The invention relates to an organic fertilizer, in particular to a special bio-organic fertilizer for leeks and a preparation method thereof. Background technique [0002] Chives are heat-resistant and cold-resistant, and have strong adaptability. They are cultivated in all parts of the north and south of my country. They are one of the most widely produced fragrant leafy vegetables in China. Leek is rich in nutrients, containing a variety of vitamins and inorganic salts such as calcium, phosphorus, and iron, and contains more crude fiber and protein. Leeks are fragrant and not only suitable for frying, stuffing and seasoning, but also have good medical effects and are deeply loved by people. Leeks are often damaged by diseases and insect pests during the production process. The main pests of leeks are leek maggots, leek moths and leafminers, and diseases include botrytis cinerea. Leek maggots are the main pests that harm leeks, especially with the d...
