Embodiment 1

[0062] Biological disease control controlled-release ginger topdressing fertilizer, the raw materials are: 520 kg of bio-control coated urea, 160 kg of potassium sulfate type nitrogen, phosphorus and potassium three-element compound fertilizer, and 320 kg of granular potassium sulfate.

[0063] Preparation:

[0064] (1) Preparation of compound biocontrol agent:

[0065] A. Penicillium solid culture: Paecilomyces lilacinus ACCC30673 was used as the strain.

[0066] Adopt PDA culture medium to make Penicillium slant seeds according to the prior art. PDA medium: 200 grams of potatoes, 20 grams of glucose, 16 grams of agar, 1000 grams of water;

[0067] Penicillium slant seeds were eluted with sterile water to prepare conidia containing Penicillium palaeus 2.31╳10 7 a suspension per gram; the suspension is inserted into a sterilized liquid medium according to a mass ratio of 4wt%. The formula of the liquid medium is: 200 grams of potatoes, 20 grams of glucose, and 1000 grams o...

Embodiment 2

[0082] Biological disease control controlled-release ginger topdressing fertilizer, the raw materials are: 600 kg of bio-control coated urea, 200 kg of potassium sulfate type nitrogen, phosphorus and potassium three-element compound fertilizer, and 200 kg of granular potassium sulfate.

[0083] The preparation method is the same as in Example 1.

Embodiment 3

[0085] Biological disease control controlled-release ginger topdressing fertilizer, the raw materials are: 500 kg of bio-control coated urea, 250 kg of potassium sulfate type nitrogen, phosphorus and potassium three-element compound fertilizer, and 250 kg of granular potassium sulfate.

[0086] The preparation method is the same as in Example 1, and the difference is that Penicillium is selected from Paecilomyces lilacinus ACCC30674, and the solid culture contains 5.48 × 10 of Penicillium conidia 10 pcs / g. The Streptomyces species was Streptomyces cereus ACCC40125, and the solid culture contained Streptomyces conidia 2.78╳10 9 pcs / g. The actinomycete strain is Actinomyces madura (ACCC40769), and the solid culture contains actinomycetes conidia 1.46╳10 9 pcs / g.

Abstract

The invention relates to a biological disease-prevention controlled-release ginger additional fertilizer, and a preparation method and application thereof. The ginger additional fertilizer is prepared from the following raw materials in parts by mass: 450-600 parts of biological preventive coated urea, 150-280 parts of potassium-sulfate nitrogen-phosphorus-potassium three-element compound fertilizer and 200-320 parts of granular potassium sulfate. The biological preventive coated urea is prepared by coating a biological preventive coating agent on granular urea. The biological preventive coating agent is compounded from penicillium, streptomycete and actinomyces solid culture and weathered coal in a mass ratio of 1:(5-7). The invention also relates to a preparation method and application method of the biological disease-prevention controlled-release ginger additional fertilizer. The biological preventive bacterial culture is added into the fertilizer coating material, the existing coating technique is not changed, and the phosphorus and potassium fertilizer nutrients are matched according to the nutrient requirements for ginger growth in medium and later periods, thereby being beneficial to disease prevention and yield increase in the ginger growth process.

Description

technical field [0001] The invention relates to a biological disease prevention type controlled-release ginger topdressing fertilizer and a preparation method and application thereof, belonging to the technical field of fertilizer production and application. Background technique [0002] Ginger (Zingiber officinale Roscoe) is a perennial herbaceous plant belonging to Zingiberaceae and Zingiberaceae. China is the main producer and exporter of ginger in the world. According to the survey by the Ministry of Agriculture, in 2010, the national ginger planting area was more than 2.3 million mu. [0003] Ginger is a crop that harvests underground rhizomes as products. This crop needs to absorb more nitrogen for the expansion of underground rhizomes, but the nitrogen supply should not be too concentrated, otherwise the aboveground stems and leaves will grow too vigorously, which is not conducive to the growth of rhizomes. However, insufficient nitrogen will also slow down the grow...
