Description

Technical Field

[0001] The present invention relates to the technical field of agriculture, and particularly to a crop conditioning composition and a preparation method thereof. Background Art

[0002] At present, some crop conditioners with the function of promoting early maturity can advance the maturity time of crops to supply the market in advance and obtain price advantages. However, generally, crop varieties often require a certain growth period to make full use of sunlight, water, and soil nutrients to accumulate more dry matter. Prematurely mature crops have insufficient growth time due to early maturity, which affects the full development of their vegetative and reproductive organs. Taking tomatoes as an example, not only are there problems such as smaller fruits and decreased yield per plant, but also the content of nutrients such as sugars and chlorophyll that need to be accumulated for a long time is reduced, resulting in a decline in the quality of crops. Summary of the Invention

[0003] The object of the present invention is to provide a crop conditioning composition and a preparation method thereof to solve the problems in the prior art that after crop conditioners promote early maturity of crops, it will lead to smaller fruits, decreased yield, low content of product nutrient components, and decline in quality.

[0016] The present invention also provides a preparation method of the crop conditioning composition, comprising the following steps: taking lipopeptide, polyglutamic acid, polyaspartic acid, nitrogen fertilizer, phosphate fertilizer, potassium fertilizer, medium micronutrient fertilizer, and vitamin by weight parts, and mixing them evenly to obtain the composition.

[0017] Preferably, the preparation method of the crop conditioning composition comprises the following steps:

[0018] (1) Taking nitrogen fertilizer, phosphate fertilizer, potassium fertilizer, medium micronutrient fertilizer, selenium fertilizer, and vitamin by weight parts, mixing them evenly, and pulverizing to obtain a first mixed powder; then taking lipopeptide, polyglutamic acid, polyaspartic acid, L-alanine, and glutathione by weight parts, mixing them evenly, drying and pulverizing to obtain a second mixed powder;

[0019] (2) Taking the first mixed powder and the second mixed powder in step (1), mixing them evenly, and then granulating, drying, and packaging to obtain the composition.

[0020] The above solution of the present invention has at least the following beneficial effects:

[0021] (1) The crop conditioning composition of the present invention comprises raw materials in the following parts by weight: 0.1 - 2 parts of lipopeptide, 0.1 - 5 parts of polyglutamic acid, 1 - 5 parts of polyaspartic acid, 0.2 - 5 parts of L-alanine, 1 - 10 parts of glutathione, 10 - 25 parts of nitrogen fertilizer, 10 - 30 parts of phosphate fertilizer, 15 - 35 parts of potassium fertilizer, 3.5 - 40 parts of medium and micronutrient fertilizer, and 0.01 - 0.05 parts of vitamin. Among them, the lipopeptide consists of a hydrophobic alkyl chain and a hydrophilic polypeptide, and has the functions of promoting plant growth and improving plant quality. The polyglutamic acid and the polyaspartic acid have a large number of carboxyl groups, which can chelate NH4 + 、K + 、Mg 2+ 、Zn 2+ and other ions, carry and transport the nutrient components in nitrogen fertilizer, phosphate fertilizer, potassium fertilizer and medium and micronutrient fertilizer, enrich them in the plant roots, stimulate the new growth of plant root hairs and root system growth, and enhance the ability of plants to absorb nutrients. The L-alanine is an amino acid that can be directly absorbed by plant roots. It is easily decomposed by microorganisms or lost with water in the soil. However, in the presence of the polyglutamic acid and polyaspartic acid, it can interact with the carboxyl and amino groups on the polyglutamic acid and polyaspartic acid molecules, affect the molecular conformation of the polyglutamic acid and polyaspartic acid, and further affect their adsorption and release characteristics of nutrients. The glutathione can participate in the processes of scavenging reactive oxygen species, detoxification, amino acid metabolism, etc. in plants. Its hydrophobic region can physically adsorb with the hydrophobic alkyl chain of the lipopeptide, form a specific microenvironment around the plant roots, change the kinetic process of plant nutrient absorption, regulate the balance of hormones in plants, and promote early maturity of plants. Under the synergistic action of the lipopeptide, polyglutamic acid, polyaspartic acid, L-alanine and glutathione, it can promote the early maturity of crops, accelerate the accumulation process of plant nutrient components, and prevent problems such as fruit shrinkage, yield decline, low nutrient content in products and quality decline caused by early maturity.

[0022] (2) The crop conditioning composition of the present invention further comprises one or more of D-sphingosine and pinoresinol diglucoside. The D-sphingosine can improve the stress resistance of plants, regulate the hormone balance of plant cells, and affect the growth and development process of plants. The pinoresinol diglucoside can promote cell elongation and division, and regulate the distribution and transport of nutrients. In particular, when 0.1 - 0.5 parts of D-sphingosine and 0.05 - 0.12 parts of pinoresinol diglucoside are used in combination, they can jointly promote the overall growth and development of plants and improve the quality of crops.

[0106] Effect Experimental Example

[0107] To verify the technical effects of the crop conditioning composition of the present invention, the following tests were conducted:

[0108] This experiment used a test field located in Qinhuangdao City, Hebei Province for tomato planting experiments. This test field is a perennial planting area with uniform soil texture. Before the experiment, soil samples were collected, and the basic nutrient information of the test field was detected as shown in Table 1.

[0109] Table 1 Basic Nutrients of the Test Field

[0110]

[0111] Tomatoes were planted in plots of the same size, and the crop conditioning compositions described in Examples 1-9 and Comparative Examples 1-6 were applied respectively. Except for applying the crop conditioning compositions described in Examples 1-9 and Comparative Examples 1-6, the remaining water and fertilizer management was uniformly managed. The test field was sown on November 15, 2023, and six batches of pickings were carried out, namely the first batch of picking on March 26, 2024, the second batch of picking on March 31, 2024, the third batch of picking on April 4, 2024, the fourth batch of picking on April 8, 2024, the fifth batch of picking on April 12, 2024, and the sixth batch of picking on April 18, 2023. The picking yields of tomatoes were counted, and their qualities were detected.

[0112] As Figure 1 shown, it is a on-site picture of the growth of tomatoes in the test field where the crop conditioning composition of Example 4 was applied before the picking period; as Figure 2 shown, it is a on-site picture of the growth of tomatoes in the test field where the crop conditioning composition of Example 4 was applied during the picking period.

[0113] After the experiment, the results are as follows:

[0114] Table 2 Tomato Yield Statistics Table

[0115]

[0116]

[0117] Table 3 Quality Indexes of Tomatoes

[0118]

[0119]

[0120] As Figure 3 shown, it is a physical picture of the tomatoes picked in the sixth batch of Example 4; as Figure 4 shown, it is a physical picture of the tomatoes picked in the sixth batch of Comparative Example 6. It can be seen that there are differences in the size of single fruits between the tomatoes of the same batch in Example 4 and Comparative Example 6.

[0121] According to the above results, the crop conditioning composition can promote the early maturity of crops, accelerate the accumulation process of plant nutrients, and prevent problems such as the reduction of fruit size, the decrease of yield, the low content of product nutrients, and the decline of quality caused by early maturity.

[0122] According to the results of Example 4 and Comparative Example 6, among the six picking batches of tomatoes, the picking peak of Example 4 appeared in the fourth batch, which was 188.3 kg, while the picking peak of Comparative Example 6 appeared in the sixth batch, which was 52.5 kg. That is, obvious early maturity occurred in Example 4, and both the yield and quality were greatly improved. According to the results of Example 4 and Comparative Examples 1-5, the lipopeptide, polyglutamic acid, polyaspartic acid, L-alanine, and glutathione all have different degrees of influence on the maturity time, yield, and quality of crops.

[0123] According to the results of Example 4 and Examples 5-9, the addition of the D-sphingosine can increase the yield of crops, but has a slight impact on the quality of crops. The addition of the pinoresinol diglucoside can improve the quality of crops and slightly increase the yield. The synergistic use of the two can significantly improve the yield and quality of crops.

[0124] As is known by common technical knowledge, the present invention can be implemented by other embodiments that do not depart from its spiritual essence or essential features. Therefore, the above-disclosed embodiments are illustrative in all aspects and not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are encompassed by the present invention.
