Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of plant growth regulators, in particular to a kind of highland barley anti-lodging regulator and the method for improving highland barley seedling stage anti-lodging ability. BACKGROUND

[0002] As the main food crop in the Qinghai-Tibet Plateau region, highland barley plays a vital role in local agricultural economy and residents' life. However, the problem of lodging seriously restricts the improvement of its yield and quality during the growth of highland barley. Due to its biological characteristics such as shallow root system, long basal internode, thin and soft stem wall, etc., highland barley is prone to lodging when encountering adverse weather conditions such as strong wind, heavy rain, hail, etc., as well as unfavorable environmental conditions such as little sunshine, low temperature stress, etc. In addition, unreasonable fertilization, irrigation and planting density, etc. will further exacerbate the risk of highland barley lodging.

[0003] Once highland barley lodges, especially in the middle and late stages of grain filling, the plants will be stacked on each other, causing the spatial distribution structure of leaves to be disrupted and the aboveground community structure to be destroyed. This not only leads to insufficient ventilation and light for plants, yellowing and rotting of lower functional leaves, and a significant reduction in photosynthesis, but also causes damage to basal internodes, disrupts the transport function of stems, hinders the transportation of assimilates, and severely inhibits the growth and development of plants, ultimately resulting in problems such as grain shrinkage and empty seeds, which significantly reduces the number of grains per ear, the bulk density and the seed setting rate of highland barley, and seriously affects its yield and quality.

[0004] Currently, although the cultivation techniques such as selecting anti-lodging varieties, reasonable close planting, reasonable application of nitrogen, phosphorus and potassium, reasonable irrigation and scientific prevention and control of diseases and pests can improve the anti-lodging ability of highland barley to some extent and reduce production losses, these methods are limited by many conditions in practical application, and the effect is often unsatisfactory. The application of chemical regulation technology, such as foliar spraying of paclobutrazol, chlormequat chloride, etc. before tillering to jointing of highland barley, can prevent excessive elongation of basal internodes and reduce the occurrence of lodging to some extent, but it also easily leads to yield reduction of highland barley. Therefore, the development of a special anti-lodging yield-increasing regulator that can effectively reduce the lodging rate of highland barley while ensuring its normal growth and development, and improve its yield and quality, has extremely important practical significance for promoting the development of plateau characteristic agriculture.

[0147] For highland barley with a seedling height of 15 cm, the spraying is performed in three layers;

[0148] The first layer is sprayed at a height of 5 cm from the base of the plant upward, focusing on the stem base;

[0149] The second layer is sprayed at the middle part of the plant;

[0150] The third layer is sprayed at the top growth point, and each layer accounts for 1 / 3 of the total spraying amount, ensuring that both sides of the leaves are sprayed.

[0151] Step six: carrying out intertillage;

[0152] Four days after spraying the regulator, the highland barley field is intertilled to increase soil permeability.

[0153] The step-by-step use method enables the components such as nutrient elements, biological active substances, and natural plant extracts in the regulator to be more efficiently absorbed and utilized by highland barley. Layered spraying enables the leaves to more fully absorb nutrients and enhance photosynthesis. The cultivation measures improve the root system growth environment and promote nutrient absorption and transportation. Test data show that after using the regulator and method of the present application, the yield of highland barley is increased by an average of 35% compared to the control field, and the quality indicators such as thousand-grain weight, bulk density, and protein content of the grains are more significantly improved, the grains are more plump, and the quality is better.

[0154] The step-by-step use method makes the application of the regulator more scientific and targeted, each operation has a clear goal and requirement, avoiding the limitations of traditional single use method. The collaborative operation with cultivation measures is simple and easy to operate, which is convenient for farmers to master and apply, further reduces the use difficulty, improves the popularization value in actual production, and has a wider application prospect.

[0155] Comparative Example 1: A common paclobutrazol foliar fertilizer was selected, and was applied to the barley at the three-leaf stage according to the recommended method and concentration in the instruction manual. No layered spraying and cultivation measures were used in combination with the present application.

[0156] Comparative Example 2: No anti-lodging regulator was used, and the barley was planted according to the conventional planting management method.

[0157] Comparison of experimental results

[0158] Comparison of anti-lodging ability: The lodging conditions of each test field were investigated and counted at the later growth stage of the barley. The results showed that the lodging rates of the barley fields in Examples 1, 2, and 3 were 5%, 4%, and 3%, respectively, while the lodging rate of Comparative Example 1 was 30%, and the lodging rate of Comparative Example 2 was as high as 45%. This indicated that the optimized use steps of the anti-lodging regulator for barley in the present application could more significantly reduce the lodging rate of the barley and improve the anti-lodging ability.

[0159] Comparison of yield: The yield of each test field was measured after the barley matured. The results showed that the yield per mu of the barley in Example 1 was 500 kg, the yield per mu in Example 2 was 520 kg, the yield per mu in Example 3 was 530 kg, while the yield per mu in Comparative Example 1 was 380 kg, and the yield per mu in Comparative Example 2 was 350 kg. This indicated that the regulator and the optimized use steps in the present application could more effectively improve the yield of the barley.

[0160] Comparison of quality: The barley grains harvested from each test field were detected for quality, including thousand-grain weight, bulk density, protein content, and other indicators. The results showed that the quality indicators of the barley grains in Examples 1, 2, and 3, such as thousand-grain weight, bulk density, and protein content, were all significantly better than those of Comparative Examples 1 and 2, and the improvement was greater than that of the unoptimized steps. This indicated that the regulator and the optimized use steps in the present application could more significantly improve the quality of the barley while improving the yield of the barley.
