FIG. 1 is a schematic flow chart of a method for realizing the reversion and tillering of rice by using the composition according to one embodiment of the application.
Detailed Description
The embodiments described below by referring to the drawings are illustrative and intended to explain the present application and should not be construed as limiting the application.
In a first aspect of the present application, the present application provides a joint fertilizer composition for rice. According to an embodiment of the present application, the combined fertilizer composition comprises: the granular fertilizer comprises a component A and a component B, wherein the component A comprises: medium elements and trace elements; the component B comprises: at least one of glutamic acid, aspartic acid, tryptophan and proline, salicylic acid, gamma-aminobutyric acid and fulvic acid, and the liquid fertilizer comprises: at least one of 5-aminolevulinic acid, glycine, alanine and histidine, a slow-release liquid nitrogen fertilizer and potassium fulvate as an ore source.
The inventor discovers that the combined fertilizer comprises the granular fertilizer and the liquid fertilizer, and the component A and the component B are added into the granular fertilizer, wherein the component A can provide comprehensive medium and trace element supplement for the growth and development of the rice in the turning green and tillering stage. The medium trace elements are the components of enzymes or coenzymes for promoting photosynthesis, respiration, substance conversion and the like in plants, and play an indispensable and irreplaceable role in the growth and development of crops. The component B can play a role in regulating and controlling growth, wherein at least one of glutamic acid, aspartic acid, tryptophan and proline is taken as a free amino acid, is a plant activator which can be directly absorbed and utilized by crops, can promote photosynthesis, improve stress resistance of crops, and is a precursor substance of various endogenous hormones and enzymes in the plants. Salicylic acid is a signal molecule in plants, has a regulating effect on the metabolism of substances in plants, and can particularly enhance the cold resistance, salt resistance and other environmental adversity stress of crops. Gamma-aminobutyric acid is an amino acid consisting of non-protein, plays a double role of metabolic substances and signal substances in plants, participates in a plurality of important physiological processes of the plants, promotes photosynthesis, influences energy metabolism, and promotes absorption of trace elements in the plants. Fulvic acid can be classified into mineral source Fulvic acid and biochemical Fulvic acid, which have the functions of stimulating the root system development of crops, improving the absorption of trace elements in crops and improving the absorption and utilization rate of macroelements. Therefore, the granular fertilizer can obviously promote the growth of rice root systems, improve root system activity, enhance stress resistance of rice, improve chlorophyll content of rice leaves, improve photosynthesis, further promote the tillering speed of rice and increase the tillering number of rice. Meanwhile, the slow-release liquid nitrogen fertilizer in the liquid fertilizer can supplement slow-release nitrogen for rice, and free amino acid comprising at least one of 5-aminolevulinic acid, glycine, alanine and histidine and mineral source potassium fulvate and 5-aminolevulinic acid have the effect of regulating crop growth, can improve root system activity, promote photosynthesis, increase effective tillering number of rice, reduce small tillering and ineffective tillering, and have obvious yield increasing effect. Therefore, the liquid fertilizer can supplement slow-release nitrogen for rice, improve root system activity, promote photosynthesis, increase effective tillering number of rice, reduce small tillering and ineffective tillering, and has obvious yield-increasing effect. Therefore, through the mutual coordination and synergistic effect of the granular fertilizer and the liquid fertilizer, the growth of the rice in the favorable direction can be continuously regulated and controlled in the turning green and tillering stage of the rice, so that the turning green and tillering speed of the rice is high, the tillering number is increased, the effective tillering rate is improved, and the rice has obvious yield-increasing potential.
Further, the mass ratio of the component A to the component B is (50-100): (5-10). Specifically, it may be 50:5, 50:10, 60:5, 60:10, 70:5, 70:10, 80:5, 80:10, 90:5, 90:10, 100:5, or 100:10, etc. The inventor finds that if the mass ratio of the component A to the component B in the granular fertilizer is too small, medium and trace elements are not sufficiently supplemented, and the growth and development promotion effect on rice is weakened; if the mass ratio of the component A to the component B in the granular fertilizer is too large, the regulation and control effect of the biological stimulation hormone is not obvious, and the synergistic effect with the component A is weakened. Therefore, the contents of trace elements and biostimulant substances in the granular fertilizer are matched, so that nutrients can be provided for the growth and development of rice, the biostimulant can be ensured to fully play roles, the trace elements and the biostimulant are synergistic, the nutrient absorption of the rice can be promoted, and the rice can grow in a favorable direction for increasing tillers.
It should be noted that the specific types of the above-mentioned intermediate elements and trace elements are not particularly limited, and those skilled in the art can select according to actual needs, for example, the intermediate elements include at least one of calcium, magnesium and silicon, and the trace elements include at least one of iron, manganese, copper, zinc, boron and molybdenum. In particular, the medium element magnesium is a chlorophyll central component and is an activator of various enzymes; the trace element zinc and the like can promote the improvement of root system activity.
Further, in the component A, the mass ratio of the medium elements to the trace elements is (3-5): (10-15). The inventor finds that, because the soil in a considerable area of China lacks microelements such as iron, manganese, copper, zinc, boron, molybdenum and the like, rice is more sensitive to the reaction of certain microelements such as zinc, therefore, in the component A, the proportion of the microelements is higher than that of the medium elements, and the rice is also a siliceous plant and has certain requirements on calcium and magnesium. Therefore, the mass ratio of the medium elements to the trace elements can provide more targeted medium and trace element supplement for rice, and the maximum efficacy is exerted.
Further, the component B comprises 1-5 parts by weight of salicylic acid, 1-10 parts by weight of gamma-aminobutyric acid, 0-2 parts by weight of glutamic acid, 0-2 parts by weight of aspartic acid, 0-1 part by weight of tryptophan, 0-1 part by weight of proline and 1-5 parts by weight of fulvic acid, wherein the parts by weight of glutamic acid, aspartic acid, tryptophan and proline are not zero at the same time. Specifically, in the above component B, the content of salicylic acid may be 1 part by weight, 2 parts by weight, 3 parts by weight, 4 parts by weight, 5 parts by weight, or the like; the content of the gamma-aminobutyric acid may be 1 part by weight, 2 parts by weight, 3 parts by weight, 4 parts by weight, 5 parts by weight, 6 parts by weight, 7 parts by weight, 8 parts by weight, 9 parts by weight, 10 parts by weight, or the like; the content of glutamic acid may be 0 parts by weight, 1 part by weight, 2 parts by weight, or the like; the content of aspartic acid may be 0 parts by weight, 1 part by weight, 2 parts by weight, or the like; the tryptophan content may be 0 parts by weight or 1 part by weight or the like; the content of proline may be 0 parts by weight or 1 part by weight or the like; the content of fulvic acid may be 1 part by weight, 2 parts by weight, 3 parts by weight, 4 parts by weight, 5 parts by weight, or the like. Wherein, the weight parts of glutamic acid, aspartic acid, tryptophan and proline are not zero at the same time. Therefore, by adopting the proportion of the component B, the substances can play a better role, the obtained granular fertilizer can obviously promote the growth of rice root systems, improve the root system activity, enhance the stress resistance of rice, improve the chlorophyll content of rice leaves, improve photosynthesis, further promote the tillering speed of rice and increase the tillering number of rice.
Further, the liquid fertilizer comprises 50-80 parts by weight of slow-release liquid nitrogen fertilizer, 1-5 parts by weight of mineral source potassium fulvate, 0-3 parts by weight of 5-aminolevulinic acid, 0-3 parts by weight of glycine, 0-3 parts by weight of alanine and 0-2 parts by weight of histidine, wherein the parts by weight of 5-aminolevulinic acid, glycine, alanine and histidine are not zero at the same time. Specifically, in the above-mentioned liquid fertilizer, the content of the slow-release liquid nitrogen fertilizer may be 50 parts by weight, 55 parts by weight, 60 parts by weight, 65 parts by weight, 70 parts by weight, 75 parts by weight, 80 parts by weight or the like; the content of the potassium fulvate serving as the mineral source can be 1 part by weight, 2 parts by weight, 3 parts by weight, 4 parts by weight or 5 parts by weight and the like; the content of 5-aminoacetopropionic acid may be 0 parts by weight, 1 part by weight, 2 parts by weight, 3 parts by weight, or the like; the content of glycine may be 0 parts by weight, 1 part by weight, 2 parts by weight, 3 parts by weight, or the like; the content of alanine may be 0 parts by weight, 1 part by weight, 2 parts by weight, 3 parts by weight, or the like; the histidine content may be 0 parts by weight, 1 part by weight, 2 parts by weight, or the like. Wherein, the weight parts of 5-aminolevulinic acid, glycine, alanine and histidine are not zero at the same time. Therefore, by adopting the liquid fertilizer proportion, the slow-release nitrogen and the biostimulant substances can be matched with each other to realize synergistic effect, so that the slow-release nitrogen can provide sustained-release nitrogen for rice, the plant growth can be regulated, the root activity and photosynthesis of the rice can be improved, the effective tiller number of the rice can be increased, the tiller number and ineffective tiller number of the rice can be reduced, and the yield increasing effect is obvious.
Further, the slow-release liquid nitrogen fertilizer contains methylol urea and triazinone. The inventor finds that by adding the methylol urea and the triazinone into the liquid fertilizer, the liquid fertilizer has low salt index and good mixing compatibility, can be directly absorbed by crops when being used for foliage spraying, can be gradually decomposed and released in the crops, and participates in physiological metabolism of the crops and is assimilated and utilized.

In the step, the granular fertilizer comprising the component A and the component B is mixed with urea and/or a high-nitrogen compound fertilizer and then applied during the first topdressing in the green-turning tillering stage of the rice. Specifically, the application may be performed 3 to 7 days after the transplanting. Therefore, the method can provide timely nutrient supply and material metabolism regulation for rice seedlings. The high-nitrogen compound fertilizer refers to a compound fertilizer with the nitrogen mass content not less than 25%. The inventor discovers that the component A and the component B can obviously promote the growth of rice root systems, improve root activity, enhance stress resistance of rice, improve chlorophyll content of rice leaves, improve photosynthesis, further promote tillering speed of rice, increase tillering number of rice, and can improve absorption and utilization rate of nitrogen without increasing fertilization times additionally when being used after being mixed with urea and/or high-nitrogen compound fertilizer. It should be noted that, the specific compositions of the component a and the component B are the same as those described above, and are not repeated here.
Further, the application mode is soil dressing, and the mass ratio of the granular fertilizer to urea and/or the high-nitrogen compound fertilizer is (1-3): (5-15). The application amount of the granular fertilizer is 1-3 kg/mu. Specifically, the application amount per mu can be 1kg, 2kg or 3 kg. The specific application amount can be increased or decreased according to the growth vigor of rice seedlings and the use condition of the current fertilizer. The usage requirement of most cases can be met in the usage range.
S200: applying liquid fertilizer during secondary topdressing in the green returning and tillering stage of rice
In the step, the liquid fertilizer is applied in the second topdressing of the rice in the green-turning tillering stage, and specifically, the liquid fertilizer is applied 5-10 days after the first topdressing. The inventor finds that the liquid fertilizer can supplement slow-release nitrogen for rice, and simultaneously improves root system activity, promotes photosynthesis, increases effective tillering number of the rice, reduces small tillers and ineffective tillers, and has obvious yield-increasing effect. It should be noted that the specific composition of the liquid fertilizer is the same as that described above, and will not be repeated here.

Therefore, nutrient substances can directly enter the body from the leaves to participate in the metabolism of crops and the synthesis process of organic matters, so that the operation efficiency can be improved. In addition, the application amount of the liquid fertilizer is 0.2-1L/mu, and specifically, the application amount per mu can be 0.2L, 0.3L, 0.4L, 0.5L, 0.6L, 0.7L, 0.8L, 0.9L or 1.0L, etc. The liquid fertilizer can be properly diluted by adding water when the foliar fertilizer is applied, the specific application amount can be increased or decreased according to the growth vigor of rice seedlings and the use condition of the current fertilizer, and the water consumption of foliar spraying is increased when the application amount is higher, so that the foliar fertilizer is favorable for uniform spraying. The usage requirement of most cases can be met in the usage range.
Further, step S200 further includes: the liquid fertilizer is mixed with the insecticidal and bactericidal agent for application. Therefore, the purposes of providing crop nutrients and preventing and controlling crop diseases and insect pests can be simultaneously realized, and the synergistic effect and the operation efficiency can be improved. It should be noted that, the specific type and application amount of the pesticide can be selected by those skilled in the art according to actual needs, so long as the liquid fertilizer and the pesticide are harmless to crops after being mixed, and the fertilizer efficiency and the pesticide effect are not reduced.

Salicylic acid is a signal molecule in plants, has a regulating effect on the metabolism of substances in plants, and can particularly enhance the cold resistance, salt resistance and other environmental adversity stress of crops. Gamma-aminobutyric acid is an amino acid consisting of non-protein, plays a double role of metabolic substances and signal substances in plants, participates in a plurality of important physiological processes of the plants, promotes photosynthesis, influences energy metabolism, and promotes absorption of trace elements in the plants. Fulvic acid can be classified into mineral source Fulvic acid and biochemical Fulvic acid, which have the functions of stimulating the root system development of crops, improving the absorption of trace elements in crops and improving the absorption and utilization rate of macroelements. Therefore, the component A and the component B can obviously promote the growth of rice root systems, improve root system activity, enhance stress resistance of rice, improve chlorophyll content of rice leaves, improve photosynthesis, further promote tillering speed of rice, increase tillering number of rice, and improve nitrogen fertilizer utilization rate without increasing fertilization times. Then, by applying the liquid fertilizer during the second topdressing of the rice in the turning green and tillering stage, the slow-release liquid nitrogen fertilizer in the liquid fertilizer can supplement slow-release nitrogen for rice, and free amino acid comprising at least one of 5-aminolevulinic acid, glycine, alanine and histidine and mineral source potassium fulvate and 5-aminolevulinic acid have the effect of regulating crop growth, can improve root system activity, promote photosynthesis, increase effective tillering number of rice, reduce small tillers and ineffective tillers, and have obvious yield increasing effect. Therefore, the liquid fertilizer can supplement slow-release nitrogen for rice, improve root system activity, promote photosynthesis, increase effective tillering number of rice, reduce small tillering and ineffective tillering, and has obvious yield-increasing effect. Therefore, the grain fertilizer and the liquid fertilizer are matched and cooperated with each other during the first topdressing and the second topdressing, so that the growth of the grain fertilizer and the liquid fertilizer in a favorable direction can be continuously regulated and controlled in the rice green-turning tillering stage, the rice green-turning tillering speed is high, the tillering number is increased, the effective tillering rate is improved, and the yield-increasing potential is obvious.
