Embodiment 1

[0042] The preparation method of rice seedling strengthening agent is as follows:

[0043] 1) Cultivation of Trichoderma harzianum: Inoculate Trichoderma harzianum into PDA medium, culture at 28°C for 3-5 days, collect spores; inoculate spores on wheat grains, cultivate at 28°C for 7 days, dry in the shade naturally, and crush wheat spare grains;

[0044]2) Cultivation of Bacillus subtilis: 3 g of yeast powder, 5 g of sodium carboxymethyl cellulose, 10 g of peptone, 2.5 g of ammonium sulfate, 5 g of sodium chloride, 2 g of dipotassium hydrogen phosphate, and constant volume of 1 L. After sterilization, take the inoculated purified Bacillus subtilis into a 500ml Erlenmeyer flask filled with sterile 200ml sporulation medium, culture at 30°C for 30h at 200rpm / min;

[0045] 3) Cultivation of Bacillus licheniformis: 5 g of beef extract, 5 g of yeast extract, 10 g of peptone, 2.5 g of ammonium sulfate, 5 g of sodium chloride, pH 7.5, and constant volume of 1 L were used to make a s...

Embodiment 2

[0052] The specific operation steps are the same as in Example 1, except that Trichoderma harzianum, Bacillus licheniformis and Bacillus subtilis are fully mixed according to the mass ratio of 1:0.5:1.5.

Embodiment 3

[0054] The specific operation steps are the same as in Example 1, except that the Trichoderma harzianum, Bacillus licheniformis and Bacillus subtilis are fully mixed according to the mass ratio of 1:0.7:1.2, and the composite microbial agent is added according to the mass ratio of 10wt%.

Abstract

The invention provides a rice seedling strengthening agent and a preparation method thereof. The rice seedling strengthening agent is mainly composed of a complex microbial inoculant and an inorganic fertilizer, the complex microbial inoculant mainly comprises trichoderma, bacillus licheniformis and bacillus subtilis; the mass ratio of the trichoderma to the bacillus licheniformis to the bacillus subtilis is 1:(0.5-1.5):(0.5-1.5). According to the rice seedling strengthening agent, biological organic components, a compound microbial agent and other components are added on the basis of a traditional seedling strengthening agent. The survival rate of seedlings can be increased, and the stress resistance and yield of crops can be improved. The rice seedling strengthening agent also has important practical significance and agricultural popularization value for solving environmental pollution, recycling resources and realizing sustainable development.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a rice seedling strengthening agent and a preparation method thereof. Background technique [0002] Rice is one of the three major food crops, and half of the world's population uses rice as a staple food. China is a big rice planting country and also a big rice consumer. The rice planting area accounts for 25.6% of the total crop planting area, and the output accounts for 31.6% of the total grain crop output. Rice production plays a very important role in our country. Rice cultivation is mainly based on seedling cultivation and transplanting, so it is particularly important to cultivate high-quality rice seedlings. [0003] In rice production, cultivating strong seedlings is the most important technical link, and has become an important factor restricting rice yield and quality improvement. Rice seedling strengthening agent is a kind of seedling-raising preparation devel...
