Problems solved by technology

Peanut is a leguminous crop that has its own ability to fix nitrogen, but the root nodules are not fully formed at the seedling stage and cannot fix nitrogen. Therefore, an appropriate amount of nitrogen fertilizer should be supplied to promote robust growth of seedlings, more branches, and effective flower bud formation. Nitrogen supply is insufficient during this period , will seriously affect the output

Embodiment 1

[0030] Example 1-Compound Fertilizer 1

[0031] The strains used in the present invention are as follows: Bacillus subtilis (Bacillus subtilis) CGMCC No. 7926, purchased from the General Microbiology Center of China Microbial Culture Collection Management Committee. Address: No. 3, No. 1, Beichen West Road, Chaoyang District, Beijing, Institute of Microbiology, Chinese Academy of Sciences, 100101. Cultivate in accordance with the conventional method on the instructions. The seed medium formula is: 20g glucose, 15g peptone, 5g sodium chloride, 0.5g beef extract, 1L water; the fermentation medium formula is: corn flour 12g, glucose 5g, soybean meal powder 20g, CaCO 3 8g, (NH4) 2 SO 4 1g, K 2 HPO 4 0.3g, MgSO 4 ·7H 2 O 0.2g, 1L water.

[0032] The characteristics of the strain are high temperature-resistant alpha-amylase enzyme activity, high heat resistance and strong acid resistance.

[0033] The characteristics of the strain are as follows:

[0034] The color of the bacterial col...

Embodiment 2

[0047] Example 2 Experiment on the effect of compound fertilizer 1, C1 and C2 on peanut growth

[0048] In an experimental field, three experimental fields with an area of ​​40 square meters were taken and labeled as compound fertilizer group 1, compound fertilizer group C1, and compound fertilizer group C2. Plant peanuts in three experimental fields at the same time. According to conventional management methods, after soil preparation, the fertilizer is applied as a base fertilizer at one time, and no fertilizer will be applied later. The results are shown in Table 1.

[0049] Table 1 Growth of each group (40 square meters experimental field)

[0050]

[0051] The experimental results show that the compound fertilizer of the present invention has a reasonable formula, contains the necessary organic components of peanuts, nitrogen, phosphorus, potassium and trace elements, and has stable quality and high efficiency. Long-term use can effectively maintain soil nutrient balance, impro...

Abstract

The invention provides a compound fertilizer for producing peanuts and a preparation method of the compound fertilizer. The compound fertilizer is prepared from potassium nitrate, urea, ammonium sulfate, monoammonium phosphate, potassium sulfate, zinc sulfate, ferrous sulfate, borax and bacillus. The compound fertilizer is comprehensive in formula and outstanding in effect and has a significant effect of improving the yield and quality of peanuts.

Description

Technical field [0001] The invention belongs to the technical field of agricultural chemistry. Specifically, the invention relates to a compound fertilizer for producing peanuts and a preparation method and application thereof. Background technique [0002] Since the 1970s, the structure of fertilizers used in my country's agricultural sector has undergone fundamental changes. The proportion of total organic fertilizers used has dropped from 100% in 1949 to about 50%. Chemical fertilizers have been used in large quantities and have played a major role in increasing agricultural production. However, the shortcomings of chemical fertilizers have also been shown. They have a great damage to the quality of cultivated land, pollute the soil, cause soil compaction, decrease fertility, and cannot guarantee the quality of agricultural products. At present, our country vigorously advocates the development of ecological agriculture, and increasingly emphasizes the rational or less use of ...
