Description
Technical Field
The invention belongs to the technical field of rice aroma enhancement, and particularly relates to a fertilizing method for enhancing the aroma of rice.
Background
The rice is one of the important staple foods for residents in China, the rice planting area in China is about 4.5 hundred million mu, the rice is the second place in the world, the total yield is 2.04 hundred million tons, the rice is the first place in the world, the yield per unit is 420 kilograms, and the rice is 1.6 times of the average level in the world. In recent years, the rice consumption in China is continuously low due to the slow influence of macroscopic economy and the adjustment of dietary structure. China has a large overstocked amount of rice every year, and a large amount of imported high-quality rice is also needed every year in China at the same time of the overstocked amount of rice. The famous high-quality rice five-common 'rice flower fragrance' in China is famous for the natural and strong fragrance. The strong rice aroma is a remarkable characteristic of high-quality rice, the price is generally higher, and a lot of poor dealers even use the business to paint the common rice or even the poor rice with essence to seek higher benefits. A technical method for increasing the fragrance of rice by using organic chemical substances such as zinc fertilizer, rare earth lanthanum element, Jiu di O, proline and the like is reported.
For example, chinese patent CN103508770A discloses a fertilizer formulation for natural aroma enhancement of wampee occupied grains of common rice seeds, which comprises the following raw materials and proportions thereof per mu: 5.52 +/-0.83 MgCl of raw materials (kg/mu)2；8.53±1.28MnCl2；1.49±0.22CuCl2；2.16±0.32ZnCl2(ii) a 0.24 ± 0.04 molybdic acid; 3.91 plus or minus 0.58 citric acid; 3.91 plus or minus 0.58 tartaric acid; 3.91 plus or minus 0.58 apples; 460 +/-69 bagasse. The fertilizing method comprises the following steps: 1) when the rice field is ploughed, bagasse is applied to 460 kg per mu and is uniformly mixed with a soil plough layer; 2) applying 15 +/-2.25 kg of KCl, 15 +/-2.25 kg of urea and 100kg of calcium, magnesium and phosphorus to each mu of rice seedlings during transplanting; 3) uniformly using water and uniformly mixing MgCl for each mu in the middle stage of tillering25.52±0.83、MnCl28.53±1.28、CuCl21.49±0.22、ZnCl22.16 plus or minus 0.32, molybdic acid 0.24 plus or minus 0.04, citric acid 3.91 plus or minus 0.58, tartaric acid 3.91 plus or minus 0.58 and malic acid 3.91 plus or minus 0.58.
However, the rice aroma-enhancing fertilization formula and the fertilization method can only be applied to aroma enhancement of specific common rice seeds which are Huanghua and account for grains, the formula is complex, most of the components of the formula are industrial finished products, the production cost is indirectly increased, and meanwhile, the cost is increased due to excessive applied fertilizers, and the large-area production is not facilitated.

(1) on the basis of conventional fertilization, when soil is prepared before rice transplanting, adding a base fertilizer into the soil, wherein the base fertilizer is formed by mixing one or more minerals containing trace elements and/or mineral processing products containing trace elements with decomposed vinegar residues;
(2) and respectively adding agricultural enzyme into the rice field in the filling period and the milk ripening period of the rice in combination with water filling, wherein the agricultural enzyme is a fermentation product obtained by mixing waste vegetables and/or fruits, waste molasses and water and then sealing and fermenting.
The conventional fertilization is the normal fertilization condition of a producer in the actual production.
In some embodiments of the present invention, preferably, the trace elements in the base fertilizer include calcium, manganese and magnesium. Suitable microelements can be selected according to actual needs or different geographic environments and added into the base fertilizer.
According to some preferable aspects of the scheme, the base fertilizer is formed by mixing dolomite powder, manganese sulfate and decomposed vinegar residues according to the weight ratio of 3-8: 1: 10-20.
Further preferably, the weight ratio of the dolomite powder, the manganese sulfate and the decomposed vinegar residues is 4-6: 1: 12-16.
In some specific embodiments of the invention, the decomposed vinegar residue accounts for 65-75% of the mass content of the base fertilizer.
According to some preferred aspects of the above aspects, the mineral and the mineral processing product are 150 to 250 mesh powder particles, respectively.
In some embodiments of the invention, the agricultural enzyme is prepared by mixing waste vegetables and/or fruits, waste molasses and water in a weight ratio of 1: 0.8-1.2, and then sealing and fermenting for 30-50 days.
Preferably, the weight ratio of the waste vegetables and/or fruits, the waste molasses and the water is 1: 0.9-1.1.
In some embodiments of the present invention, in the step (1), the base fertilizer is applied in an amount of 20-30 kg per mu.
In some embodiments of the invention, in the step (2), the agricultural enzymes are respectively used in an amount of 10-15 kg per mu in the grain filling stage and the milk ripening stage of the rice.
Due to the adoption of the technical scheme, compared with the prior art, the invention has the following advantages:
according to the invention, a self-made fertilizer containing trace elements and agricultural enzyme are applied to the growth process of rice by stages by using a conventional fertilization technology, so that natural aroma enhancement in the rice cultivation process is realized, meanwhile, on one hand, the problem of maximized utilization of resources such as vinegar residue, waste fruits/vegetables, waste molasses and the like is solved by using the agricultural enzyme, the production cost is saved, and operability is provided for large-area planting, on the other hand, the activity of the rice enzyme is improved by using the trace elements such as magnesium, calcium, manganese and the like and the agricultural enzyme, and the expression of a rice aroma gene is promoted.
