Technical Field
The invention mainly relates to the technical field of rice cultivation in severe saline-alkali soil, in particular to a rice topdressing method in severe saline-alkali soil.
Background
The saline-alkali soil has the characteristics of high pH value, strong alkalinity, multiple types of soda, poor permeability, heavy soil viscosity, cold soil slurry, slow nutrient release, low organic matter content, low soil basic fertility and the like. If the rice is planted on the severe saline-alkali land, the application of fertilizer must be emphasized, so that the use amount of fertilizer is reduced as much as possible, and the damage of salt to the rice caused by secondary salinization is avoided.
After the rice seedlings are delayed, along with the increase of growth amount, particularly when the rice enters a tillering stage, root systems continuously extend downwards, the degree of damage caused by salt is aggravated (the salt content of the lower layer is relatively high), the capacity of the root systems for absorbing nutrients and water is weakened, the supply of nutrients required by the rice at the moment can not be met, the effective tillering of the rice and the joint pulling and ear bearing of the rice are seriously influenced, and the rice growth stage is delayed to different degrees.
Disclosure of Invention

In order to realize the purpose, the invention adopts the technical scheme that:
a method for topdressing paddy rice in severe saline-alkali soil by using roots comprises the following steps: (1) the potassium dihydrogen phosphate and the urea are selected as fertilizers, the fertilizers are respectively and completely dissolved according to the amount of each mu, and then are mixed together, and a proper amount of water is added to the fertilizers, and the fertilizers are fully stirred uniformly and sprayed on the leaf surfaces of the rice.
(2) When the rice enters a tillering stage, a joint-pulling and booting stage, a breaking stage, a heading-out stage, a heading-leveling stage and a filling stage, multiple times of extra-root topdressing are adopted according to the growth condition of the rice.
Further, the method also comprises the following steps of (3) fertilizer spraying time: the method comprises the following steps of starting to remove dew eight hours in the morning, finishing about ten hours in the morning, starting to finish before the sunset after three hours in the afternoon, and spraying fertilizer again when the rain influences the leaf surface absorption effect within 6 hours after the fertilizer is sprayed;
(4) water consumption per mu: the water consumption for spraying per mu of leaf surface is 25-35 kg.
A top dressing formula of a method for top dressing paddy roots in severe saline-alkali soil is disclosed, wherein the top dressing formula comprises a formula in a growing period of paddy rice: monopotassium phosphate, urea and zinc sulfate, wherein the formula of the rice in the reproductive growth period comprises the following components: potassium dihydrogen phosphate, urea and boric acid.
Further, the formula concentrations include: potassium dihydrogen phosphate 0.3%, urea 0.5%, zinc sulfate 0.1-0.15%, and boric acid 0.1-0.15%.
Compared with the prior art, the invention has the beneficial effects that:
the rice is subjected to multiple times of external topdressing in different growth periods of the rice, nutrients can be effectively supplemented through direct absorption of the leaves, the growth of growth and reproduction of the rice are promoted, and the high yield, high quality and high efficiency of rice production in severe saline-alkali soil are ensured.
Detailed Description
In order to make the technical field of the present invention better understood, the technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention.
The invention provides a method for topdressing paddy rice roots in severe saline-alkali soil, which comprises the following steps: (1) the potassium dihydrogen phosphate and the urea are selected as fertilizers, the fertilizers are respectively and completely dissolved according to the amount of each mu, and then are mixed together, and a proper amount of water is added to the fertilizers, and the fertilizers are fully stirred uniformly and sprayed on the leaf surfaces of the rice.
(2) When the rice enters a tillering stage, a joint-pulling and booting stage, a breaking stage, a heading-out stage, a heading-leveling stage and a filling stage, adopting multiple times of extra-root topdressing according to the growth condition of the rice;
(3) and (3) fertilizer spraying time: the method comprises the following steps of starting to remove dew eight hours in the morning, finishing about ten hours in the morning, starting to finish before the sunset after three hours in the afternoon, and spraying fertilizer again when the rain influences the leaf surface absorption effect within 6 hours after the fertilizer is sprayed;
(4) water consumption per mu: the water consumption for spraying per mu of leaf surface is 25-35 kg.
The variety of the fertilizer for the additional fertilizer outside the root is selected, and the potassium dihydrogen phosphate and urea are generally selected for the additional fertilizer outside the root. The heavy saline-alkali soil can reduce the effectiveness of zinc and boron in plough layer soil, so that zinc sulfate can be used in cooperation with the heavy saline-alkali soil in the growth period of rice breeding, and boric acid can be used in cooperation with the heavy saline-alkali soil in the growth period of rice breeding. Other varieties of foliar fertilizers can also be selected.
In the test of the present invention, the rice seedlings after topdressing on the severe saline-alkali soil were compared with the rice seedlings of the control group as shown in the following table:
a top dressing formula of a method for top dressing paddy roots in severe saline-alkali soil is disclosed, wherein the top dressing formula comprises a formula in a growing period of paddy rice: monopotassium phosphate, urea and zinc sulfate, wherein the formula of the rice in the reproductive growth period comprises the following components: potassium dihydrogen phosphate, urea and boric acid.
The formula concentration selection comprises the following steps: potassium dihydrogen phosphate 0.3%, urea 0.5%, zinc sulfate 0.1-0.15%, and boric acid 0.1-0.15%.
The extra-root topdressing technology is a key measure for rice planting in severe saline-alkali land areas, can effectively supplement the requirement of rice on nutrients, and overcomes the defect that the nutrient absorption is hindered due to the influence of salt damage on root system development.
Finally, it should be noted that: the above examples are only intended to illustrate the invention and do not limit the technical solutions described in the present invention; thus, while the present invention has been described in detail with reference to the foregoing examples, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted; all such modifications and variations are intended to be included herein within the scope of this disclosure and the appended claims.
