Description

Technical Field

[0001] The invention relates to the technical field of rice planting, and further to a planting method for high-quality rice. Background Art

[0002] As the world's second largest crop, rice has long been the main source of nutrition and energy for residents in my country and Southeast Asia. With the continuous progress of society and the steady improvement of people's living standards, people's dietary structure has changed significantly. Consumers have increasingly higher requirements for rice varieties and quality. They not only pursue food safety, but also prefer high-quality rice with health and nutritional functions. Therefore, improving rice quality has always been the focus of the planting and processing industries. In order to improve the quality of rice, we can use two methods: one is to use genetic breeding technology to cultivate new varieties rich in nutrients; the other is to improve the quality of the original varieties by improving the cultivation process, such as improving soil quality and reasonable fertilization. However, genetic breeding technology has problems such as long variety breeding cycle, great environmental impact of varieties, and high seed cost. The improved cultivation process has a short production cycle and low investment, which can reduce the burden on farmers and promote industrial upgrading and increase farmers' income.

[0003] EM bacteria (Effective Microorganisms) is a multifunctional biological agent composed of more than 80 kinds of microorganisms, including photosynthetic bacteria, lactic acid bacteria, yeast, actinomycetes and filamentous fungi. It is widely used in agricultural planting, breeding and environmental protection. In the planting industry, EM bacteria can promote the decomposition of soil organic matter, enhance the beneficial microbial community and improve the soil environment.

[0004] How to skillfully combine EM bacteria with the rice planting process to cultivate rice with higher nutritional value and excellent quality has become an urgent problem that technicians in this field need to solve. Summary of the invention

[0005] In view of the problem that the existing rice has low nutritional value, the object of the present invention is to provide a high-quality rice planting method provided by the present invention, in the rice seedling stage and after the seedlings turn green, a milk enzyme liquid fertilizer rich in multiple nutrients is sprayed, which provides nourishment for the growth of the rice seedlings and promotes the rapid growth of the seedlings. Further, in the rice heading stage, the end of flowering and the filling stage, special fermented milk is sprayed, and the protein in the milk is fermented and converted into amino acids, small molecule peptides and other nutrients, which are easy for rice to absorb, and these ingredients provide rich nutrients required for its growth. Further, EM bacteria can decompose the protein, fat and lactose in the milk, and convert these macromolecules into small molecules, such as amino acids, fatty acids and monosaccharides, which are easier for rice leaves to absorb, and finally improve the taste and quality of rice. The fermented milk and milk enzyme liquid fertilizer provided by the present invention are both green fertilizers, which help promote the sustainable development of agriculture and reduce the negative impact of chemical fertilizers on the environment.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0007] A method for planting high-quality rice comprises: rice growth treatment: applying fermented milk at the booting stage, the end of flowering stage and the grain filling stage, wherein the fermented milk is prepared by mixing fresh milk, honey and EM bacteria and then fermenting them.

[0008] In some embodiments, in the fermented milk, the mass ratio of the fresh milk, the honey and the EM bacteria is 25:5:1; and the fermentation time is 7 days.

[0009] In some embodiments, the fermented milk is sprayed once at the booting stage and the end of flowering stage; the fermented milk is sprayed three times at the filling stage with an interval of 5-7 days; the spraying amount of the fermented milk is 30 kg / mu for each of the five sprayings.

[0010] In some embodiments, before the rice growth treatment, the method further includes: seedling treatment: applying milk enzyme liquid fertilizer to the seedlings during the seedling raising process and after the seedlings turn green; the milk enzyme liquid fertilizer is prepared by mixing fresh milk, honey and lactic acid bacteria and then fermenting them.

[0011] In some embodiments, in the milk enzyme liquid fertilizer, the ratio of fresh milk: honey: lactic acid bacteria is 30:10:1; and the fermentation time is 3 months.

[0012] In some embodiments, during the seedling raising process, the milk enzyme liquid fertilizer is sprayed 3-5 days before the seedlings are transplanted, and the spraying amount is 100 ml / m 2 ; and / or, spraying the milk enzyme liquid fertilizer within 1 week after the seedlings turn green, with a spraying amount of 4L / mu.

[0013] In some embodiments, the planting method further comprises: field preparation: during the field preparation process, base fertilizer is applied according to soil fertility.

[0014] In some embodiments, the base fertilizer is applied one month before transplanting and rotary tillage is performed after application; the base fertilizer includes rapeseed cake organic fertilizer, sheep manure organic fertilizer and microbial fertilizer, the amount of the rapeseed cake organic fertilizer is 200kg / mu, the amount of the sheep manure organic fertilizer is 500kg / mu, and the amount of the microbial fertilizer is 20kg / mu.

[0015] In some embodiments, the planting method further comprises: soil treatment of the planting plot: planting green manure plants on the planting plot after rice is harvested, and crushing the green manure plants into the soil during their growth period.

[0016] In some embodiments, the planting method further comprises: harvesting and storing: harvesting the rice after it matures, and storing it at low temperature after natural drying.

[0017] Compared with the prior art, the method for growing high-quality rice provided by the present invention has the following beneficial effects:

[0018] 1. In the high-quality rice planting method provided by the present invention, specially prepared fermented milk is sprayed during the rice booting stage, the late flowering stage and the grain filling stage. The fresh milk in the fermented milk contains amino acids, biological proteins, lactic acid and other nutrients, which provide the required nutrients for rice growth. For example, biological proteins can effectively prevent the occurrence of viruses. Fresh milk can also be used as a carrier to help other nutrients better adhere to rice leaves. Honey contains fructose and glucose, which provide an instant energy source for plants and can also help absorb other nutrients. The EM bacteria sprayed on the rice leaves can use solar thermal energy to synthesize antioxidants, amino acids, sugars and various physiologically active substances, further promote the growth of rice, and can also decompose pesticides, providing a strong guarantee for the green growth of rice.

[0019] 2. In the planting method provided by the present invention, a special milk enzyme liquid fertilizer is applied during the seedling raising process and after the seedlings turn green. The milk enzyme liquid fertilizer contains rich organic matter and nutrients required for plant growth. It is directly sprayed on the leaves and quickly absorbed through the stomata of the leaves to quickly supplement the nutrients required by the plants. It can promote the synthesis of green pigments in the leaves of the seedlings and improve the efficiency of photosynthesis, thereby increasing the accumulation of nutrients. The use of organic milk enzyme liquid fertilizer can also reduce the use of chemical fertilizers and reduce pollution to the environment, which is in line with the development direction of green agriculture;

[0020] 3. By adopting the planting method provided by the present invention, the protein and amino acid content of rice can be significantly enhanced. Specifically, when compared with the control group not treated with fermented milk, the rice treated with fermented milk achieved a significant increase of 15.77% in protein content. Similarly, the sum of 16 essential and non-essential amino acids also showed a significant increase of 29.59%. This improvement not only improves the nutritional value of rice, but also further verifies the effectiveness and practical value of this planting method in optimizing rice quality, bringing consumers a healthier and more nutritious food choice.

[0026] Example 1

[0027] The present invention provides a method for growing high-quality rice, the steps comprising:

[0028] Rice growth treatment: Fermented milk was applied during the rice booting stage, the late flowering stage and the grain filling stage. The fermented milk was obtained by fermenting a mixture of fresh milk, honey and EM bacteria.

[0029] Furthermore, in the above-mentioned fermented milk, the mass ratio of fresh milk, honey and EM bacteria is 25:5:1, wherein the honey is preferably molasses. During the fermentation of the fermented milk, a densely woven gauze is used to cover the barrel mouth to ensure air permeability. The fermentation time is preferably 7 days.

[0030] Furthermore, the specific application process of fermented milk in the rice growth treatment is as follows: spray the fermented milk once at the rice booting stage and the end of flowering stage, spray the fermented milk three times in the grain filling stage, with an interval of 5-7 days, and the spraying amount of the 5 sprayings of fermented milk is 31kg / mu, and additional spraying is performed in case of rain. In addition, the application method can also be selected in the form of irrigation, and the fermented milk and irrigation water are mixed in a certain proportion and can be directly used for irrigation.

[0031] In some embodiments, before the above-mentioned rice growth treatment, it also includes: seedling treatment: applying milk enzyme liquid fertilizer to the seedlings during the seedling raising process and after the seedlings turn green, the milk enzyme liquid fertilizer is made by mixing fresh milk, honey and lactic acid bacteria and fermenting them.

[0032] Furthermore, in the milk enzyme liquid fertilizer, fresh milk: honey: lactic acid bacteria = 30:10:1, wherein the honey is preferably natural honey. During the fermentation process of the milk enzyme liquid fertilizer, a densely woven gauze is also used to cover the barrel mouth to ensure air permeability. The fermentation time is 3 months.

[0033] Furthermore, the specific process of applying milk enzyme liquid fertilizer in seedling treatment includes: during the seedling raising process, spray milk enzyme liquid fertilizer 3-5 days before transplanting the seedlings, with a spraying amount of 100ml / ㎡, and spray milk enzyme liquid fertilizer within 1 week after the seedlings turn green, with a spraying amount of 4L / mu.

[0034] In some embodiments, the planting method also includes: field preparation: during the field preparation process, base fertilizer is applied according to the soil fertility. The base fertilizer can be selected from common organic fertilizers on the market, such as straw return, rapeseed cake, bean cake, and inorganic fertilizers and microbial fertilizers can also be used.

[0035] Furthermore, the above-mentioned basal fertilizer is preferably applied one month before transplanting, and rotary tillage is performed after application.

[0036] The above-mentioned base fertilizers are preferably rapeseed cake organic fertilizer, sheep manure organic fertilizer and microbial fertilizer, and the application amounts are: rapeseed cake organic fertilizer is 200kg / mu, sheep manure organic fertilizer is 500kg / mu, and microbial fertilizer is 20kg / mu.
