Description

Technical Field

[0001] The invention belongs to the technical field of agriculture and relates to a dry preparation formula for regulating the growth of fruit trees and a use method thereof. Background Art

[0002] With the development of modern agricultural technology, fruit tree growth regulation technology plays a key role in improving fruit yield and quality. Traditional pesticide application methods such as spraying and irrigation have problems such as unstable efficacy, waste of resources and environmental pollution.

[0003] Root fertilization is to apply fertilizer to the soil, and the roots absorb the nutrients needed for the growth of fruit trees. This method is widely used, but there are the following problems:

[0004] Nutrient loss: Due to the fixation of the soil and the scouring of water, some nutrients cannot be effectively absorbed by the roots, resulting in waste. Slow nutrient conduction: It takes a certain amount of time for nutrients to be conducted from the soil to various parts of the fruit tree, and it is difficult to quickly meet the needs of the tree. Environmental pollution: Excessive fertilization may cause soil and water pollution and damage the ecological environment.

[0005] Foliar fertilization is to spray fertilizer on the leaves and let them absorb directly. Although the absorption speed is fast, there are also the following problems:

[0006] Leaf burn: High concentrations of fertilizers may cause leaf burns, affecting photosynthesis and the health of fruit trees. High frequency of fertilization: Fertilizer effect lasts for a short time, and frequent fertilization is required, which increases labor intensity and costs. Application restrictions: Fertilizers are greatly restricted by weather conditions, such as rainy days or high temperatures.

[0007] There are many problems in the above existing technical solutions: Insufficient nutrient absorption: Root fertilization and irrigation application are prone to nutrient loss and low absorption efficiency. Short duration of fertilizer effect: Foliar fertilization requires frequent application, which increases cost and labor intensity. Environmental pollution: Excessive fertilization and uneven application may cause soil and water pollution. Leaf burns: Foliar fertilization is prone to leaf burns, affecting the health of fruit trees. There is an urgent need in the prior art for a preparation that can be applied directly through the trunk. Summary of the invention

[0047]

[0048] Example 4

[0049] Two-factor three-level completely randomized block design of uniconazole: (Factor A: agent concentration, level 1 1200ppm, level 2 1500mg / L, level 3 1800mg / L; Factor B: application time, level 1 May 20, level 2 May 30, level 3 June 10), a total of 6 treatments, each treatment selected 9 5-year-old apple trees with similar growth conditions in high spindle shape, before application, remove old bark and other impurities on the surface of the trunk, use a brush to evenly apply each treatment at a height of 30cm-70cm on the trunk. In addition to using uniconazole, the compound agents include: potassium dihydrogen phosphate 3500mg / L; 6-benzylaminopurine 400mg / L; S-inducing agent 28mg / L; sodium sulfate 600mg / L; amino acid mixture 400mg / L; carboxymethyl cellulose 125mg / L; polyoxyethylene (20) sorbitan monooleate 25mg / L; CK1: except for not spraying the test agent, spraying with clean water is used as the control, and other agents and management measures are the same as the treatment; CK2: no treatment is performed.

[0052]

[0053] Compared with root fertilization, the fertilization method provided in the embodiment of the present invention can supplement the deficiency of root nutrient absorption; the nutrient absorption is fast, which can meet the needs of plants in time; it directly supplies nutrients to plants, which can prevent the fixation and transformation of nutrients in the soil; it directly affects the metabolism of crops, promotes root nutrition and improves quality; it saves fertilizer and is economical and efficient. Compared with foliar fertilization, the fertilizer effect lasts longer, the concentration range is wider, and the phenomenon of leaf burn caused by improper concentration of foliar fertilization will not occur.

[0054] Under the environmental conditions in the arid areas of Northwest China, the ground temperature rises slowly in early spring, while the air temperature rises quickly, resulting in a late root sprouting in spring and an early sprouting of the branches above ground. The weak root vitality affects the nutrient supply of the above-ground tree. To ensure the normal growth of the spring shoots of fruit trees, applying the formula in Example 1 of the present invention to the trunk before the tree sprouts can effectively ensure the nutrients required for tree growth, and effectively solve the problem that the fruit trees cannot meet the growth and development requirements due to the influence of the planting habitat during the annual growth cycle of the fruit trees.

[0055] Affected by the above-mentioned environmental conditions, due to the late germination of the root system, the time for the tree to begin to utilize the stored nutrients is delayed, which is prone to problems such as late stop of spring shoot growth, insufficient differentiation of flower buds and poor quality. In the early stage of flower bud differentiation, applying the formula in Example 2 of the present invention to the trunk can effectively control the vigorous growth of the tree, provide the nutrients required for flower bud differentiation, ensure sufficient differentiation of flower buds, and ensure the orchard yield in the following year.

[0056] Comparative Example

[0057] Trunk fertilization directly applies fertilizer to the trunk or branches. The fertilizer penetrates into the tree through the bark, directly affecting the growth and nutrient supply of the tree. Compared with conventional management in production, the commonly used methods of regulating fruit tree management using coatings include pruning, fertilization, and irrigation adjustment. These methods may have the following shortcomings: High labor intensity: pruning and other physical methods require a lot of manpower and are complicated to operate. Unstable effect: The effect of fertilization and irrigation control is easily affected by environmental factors, and it is difficult to stably control the tree vigor. Strong stress response to fruit trees: Improper pruning or fertilization may cause stress response in fruit trees, affecting tree vigor and yield. High cost: Frequent fertilization, pruning and other means require continuous investment, which increases management costs.

[0058] Technical solution of the present invention: The present invention proposes a method for controlling the vigor of fruit trees by means of a dry preparation formula for regulating the growth of fruit trees. The formula can supplement nutrients and make the tree sprout in advance; during the flower bud differentiation period, it can control the tree vigor and promote flower bud differentiation.

[0059] Taking the control test as a comparative example, if the reaction temperature is 20-50℃, we can provide the test plan corresponding to the reaction temperature outside the range of 20-50℃.

[0060] At the same test site, foliar and root control tests were also conducted. After comparison, the embodiment showed the best effect and the largest number of flower buds in the next year.

[0061] Comparative Example 1 Test plan: The test adopts a completely randomized block test: spraying 600 mg / L of naphthylacetic acid, boric acid (550 mg / L); zinc sulfate (350 mg / L), magnesium sulfate (550 mg / L), amino acid mixture (8500 mg / L), seaweed extract (5500 mg / L), carboxymethyl cellulose (125 mg / L), polyoxyethylene (20) sorbitan monooleate (25 mg / L). The spraying time is: March 20, March 30, and April 10. CK: Except for not spraying the test agent, spraying with clean water is used as the control, and other agents and management measures are the same as the treatment.

[0062] Table 3 Experimental treatment effects

[0063]

[0064] The test results show that the comprehensive data of the Zt2 treatment is relatively good, that is, the pesticide was sprayed on March 30, but compared with the best embodiment, the effect is relatively poor.

[0065] Foliar spraying of 1500mg / L of uniconazole, 3500mg / L of potassium dihydrogen phosphate, 400mg / L of 6-benzylaminopurine, 28mg / L of S-inducible, 600mg / L of sodium sulfate, 8500mg / L of amino acid mixture, 125mg / L of carboxymethyl cellulose, and 25mg / L of polyoxyethylene (20) sorbitan monooleate were carried out. The spraying time was May 20, May 30, and June 10. CK: Except for not spraying the test agent, the control was sprayed with clean water, and other agents and management measures were the same as the treatment.

[0068] The test results show that the comprehensive data of the Zt2 treatment is relatively good, that is, the pesticide spraying treatment on May 30, but compared with the best embodiment, the effect is relatively poor.
