Embodiment 1

[0028] Embodiment 1: prepare according to the following ratio (percentage by weight)

[0029] 26% of solid medium coated with film, 1% of potassium dihydrogen phosphate, 5% of potassium sulfate, 32% of clay powder, 3% of zinc sulfate, 8% of urea, and 25% of humus soil. This fertilizer can be used for fertilizing Jatropha curcas in early spring.

Embodiment 2

[0030] Embodiment 2: prepare according to the following ratio (percentage by weight)

[0031] 30% of solid medium coated with film, 10% of calcium superphosphate, 5% of potassium chloride, 2 to 5% of bentonite powder, 2% of zinc sulfate, 5% of urea, and 23% of humus. The fertilizer can be used for transplanting annual Jatropha curcas cutting seedlings and fertilizing in summer flowering period.

Embodiment 3

[0032] Embodiment 3: carry out as follows:

[0033] 1. Prepare solid medium, consisting of (percentage by weight):

[0034] Humic soil 60% sucrose 4% calcium carbonate 1%

[0035] Potassium Monobasic Phosphate 1% Compost 34%, Total 100%.

[0036] 2. Envelope:

[0037] Use 90-150 mesh clay powder or bentonite powder for coating, mix according to coating material: mycorrhizal bacteria = 1:3 for 5-10 minutes.

[0038] 3. Preparation:

[0039] Mix the solid medium and peat soil (the ratio of the two is 1:50), then grind to 50 mesh, add water and stir evenly, and keep the water content at 35-45%, and then the mycorrhizal bacteria (the used mycorrhizal bacteria are The arbuscular mycorrhizal fungi purchased from the Institute of Plant Nutrition and Resources, Beijing Academy of Agriculture and Forestry Sciences "China Arbuscular Mycorrhizal Fungi Germplasm Resource Bank (BGC)" were inoculated onto the above-mentioned medium, and piles of fungi were established, and the piles wer...

Abstract

The invention discloses a Jatropha curcas mycorrhizal fungi compound fertilizer, which comprises one or more arbuscular mycorrhizal fungi containing glomus and gigaspora that are served as the mycorrhizal fungi. The compound fertilizer consists of 20-30 percent of the mycorrhizal fungi, 1-12 percent of phosphate fertilizer, 2-18 percent of potassium fertilizer, 8-15 percent of nitrogenous fertilizer, 2-3 percent of zinc sulfate and 20-50 percent of humus soil. The compound fertilizer of the invention can improve the absorption ratio of Jatropha curcas root absorbing soil nutrition, meet the growth, development and fruit bearing of the Jatropha curcas, improve soil ecological environment and increase seed yield.

Description

1. Technical field [0001] The invention relates to a compound fertilizer and a preparation method thereof, more particularly to a jatropha mycorrhizal fungus compound fertilizer and a preparation method thereof. 2. Background technology [0002] Jatropha carcas L. is a drought-tolerant and barren-tolerant multipurpose tree species widely distributed in tropical or subtropical regions. my country is mainly distributed in Yunnan, Sichuan, Guangxi, Guangdong, Hainan and other places. Its seeds and sap are widely used in medicine, chemical industry, protein feed, etc. In particular, the crude fat mixture obtained by pressing from seeds is an ideal environmental-friendly mechanical fuel after chemical transformation. In addition, Jatropha curcas is an ideal ecological tree species in dry and hot valley areas. In recent years, the provinces in Southwest my country have carried out large-scale artificial planting and industrialization of Jatropha curcas. However, during the cur...
