Problems solved by technology

[0004] In addition, the current production of rice seedling-raising substrates is still mainly based on nutrient soil, and peat, vermiculite, soil and other raw materials are added to it, but none of them can alleviate the adverse effects of cold stress on rice seedling raising.

Embodiment 1

[0036] This embodiment provides a low-temperature-resistant rice seedling-raising substrate, which includes: 50 parts of crop straw, 22 parts of poultry manure, 30 parts of fruit juice production residue, 0.1 part of fermentation agent, 12 parts of filler, water retention 1.0 parts of agent, 0.1 parts of cold-resistant regulator, 12 parts of biomass raw materials, and 15 parts of binder.

[0037] Wherein, by weight percentage, the fermented bacterial agent includes: the strain filling matrix, the strain breeding carbon source and the fermentation strain, wherein, the weight ratio of the strain filling matrix, the strain propagation carbon source and the fermentation strain It is (90-100): (10-20): 1, preferably 100:15:1, wherein, the filler matrix of the strains includes wood chaff; the carbon source for the propagation of the strains includes sucrose; the fermented strains Including one or more of photosynthetic bacteria, yeast, actinomycetes, lactic acid bacteria, spores, ni...

Embodiment 2

[0046] The difference between this example and Example 1 is that, in parts by weight, the low temperature resistant rice seedling raising substrate in this example consists of the following components: 60 parts of crop straw, 30 parts of poultry manure, 30 parts of fruit juice production residue 0.2 parts, 0.2 parts of fermentation agent, 12 parts of filler, 0.8 parts of water retention agent, 0.15 parts of cold-resistant regulator, 18 parts of biomass raw materials, and 12 parts of binder.

[0047] The cold resistance regulator is a brassinolide solution with a concentration of 0.01 g / L.

[0048] Others are the same as in Embodiment 1, and will not repeat them here.

Embodiment 3

[0050] The only difference between this example and Example 1 is that, in parts by weight, the low-temperature resistant rice seedling raising substrate in this example includes: 55 parts of crop straw, 25 parts of poultry manure, 23 parts of fruit juice production residue, fermented bacteria 0.18 parts of additives, 14 parts of fillers, 0.6 parts of water retaining agents, 0.14 parts of cold-resistant regulators, 15 parts of biomass raw materials, and 16 parts of binders.

[0051] The cold resistance regulator is a β-aminobutyric acid solution with a concentration of 0.005g / L.

[0052] Others are the same as in Embodiment 1, and will not repeat them here.

Abstract

The invention relates to a low-temperature-resistant rice seedling raising substrate and a preparation method thereof. The low-temperature-resistant rice seedling raising substrate comprises the following components in parts by weight: 50-60 parts of crop straw, 20-30 parts of livestock manure, 20-30 parts of juice production residues, 0.1-0.2 part of a fermentation inoculant, 10-15 parts of a filler, 0.5-1.0 part of a water-retaining agent and 0.1-0.2 part of a cold-resistant conditioning agent. The cold-resistant conditioning agent and other components with a heat preservation function are added into the rice seedling raising substrate, so that the germination rate of rice under the cold condition is remarkably increased, and the inhibition effect of cold stress on rice growth is relieved.

Description

technical field [0001] The invention relates to the field of rice seedling raising, in particular to a low-temperature resistant rice seedling raising substrate and a preparation method thereof. Background technique [0002] Rice plays an important role in food production and is one of the main food crops in the world. In temperate and high altitude regions, low temperature stress is an important obstacle in rice production. [0003] Especially in the production of early rice, it is easy to suffer from late spring cold, sudden drop in temperature and continuous rainy weather, which will cause injury and death of early indica rice seedlings, resulting in reduced production. According to statistics, the annual loss of rice due to low temperature and chilling damage is about 3 to 5 billion kilograms. About 71.8 million mu of early rice is produced in my country every year. How to effectively reduce the impact of low temperature stress on early rice production, especially the ...
