Description

Technical Field

[0001] This invention belongs to the technical fields of bamboo forest cultivation, fertilizer preparation, and bamboo shoot processing, and specifically relates to a fertilization method for moso bamboo forests based on microbial hydrolysis of small molecule fish peptide fertilizer. Background Technology

[0002] Moso bamboo (Phyllostachys edulis), belonging to the genus Phyllostachys of the Poaceae family, is a monopodial, scattered, evergreen, tree-like bamboo species. It is the most widely distributed and highest-yielding bamboo species in my country. Due to the superior quality and high yield of its bamboo shoots, moso bamboo is an important economic bamboo species for shoot production in my country. Among moso bamboo shoots (spring shoots, whip shoots, and winter shoots), whip shoots are the most delicious. Whip shoots are rich in protein, fiber, vitamins, and minerals such as iron, calcium, and phosphorus. They are not only tender and nutritious, but their production season coincides with the off-season for fresh shoots in summer and autumn, making them highly sought after by consumers and resulting in a market demand that exceeds supply. This makes them an important economic source for moso bamboo forests. However, the yield of whip shoots in extensively managed moso bamboo forests is generally low, resulting in poor per-acre economic benefits. To improve the economic benefits of moso bamboo forests, bamboo farmers have applied large amounts of chemical fertilizers, which has to some extent increased yield and per-acre value. However, due to the current imperfections in bamboo forest cultivation technology and the lack of scientific and precise fertilization techniques, the excessive application of fast-acting chemical fertilizers in the blind pursuit of bamboo shoot yield has caused serious damage to the ecological environment. This is mainly manifested in soil salinity accumulation, soil organic matter mineralization, reduced soil growth suitability, and decreased micronutrient availability, resulting in a significant reduction in the taste and nutritional content of bamboo shoots. Soil eutrophication also exacerbates water and air pollution, creating food safety risks and directly impacting the sustainable development of bamboo forest management. Currently, methods for alleviating these problems in bamboo forests for shoot production mainly focus on optimizing fertilization depth and timing, targeted fertilization, soil testing and formula fertilization, and nutrient diagnosis fertilization to improve fertilizer utilization and reduce the amount of chemical fertilizers used. However, existing fertilization methods cannot improve the soil ecological environment or enhance the growth suitability of bamboo plants, nor can they increase bamboo shoot yield and quality.

[0003] Shi Ying et al.'s report, "Analysis of the Influence of Different Fertilization Methods on Bamboo Shoot Yield and New Bamboo Quality," reported several fertilization methods for moso bamboo forests, including fertilization at the bamboo stump. The comparison found that targeted fertilization at the bamboo stump could improve fertilizer utilization and increase bamboo shoot yield, but it still could not improve the soil ecology of the bamboo forest or enhance the quality of bamboo shoots. Invention patent CN 112772084 A discloses a method for reducing fertilizer application in Lei bamboo forests. This method first adjusts the bamboo forest structure and uses a fan-shaped ring trench application method when adding compound fertilizer to improve fertilizer utilization, but it cannot increase bamboo shoot yield or mitigate the soil ecological damage caused by excessive fertilization. Invention patent CN 109168521 B discloses a formula fertilization method for moso bamboo shoot forests. This method requires monitoring bamboo forest environmental factors before fertilization, screening environmental factors associated with bamboo shoot yield, and constructing a minimal dataset to determine the nutrient allocation ratio, thereby improving fertilizer utilization efficiency and bamboo shoot yield. However, this method involves a large amount of data collection and analysis in the early stages, is difficult to operate, and cannot improve the soil ecological environment or enhance bamboo shoot quality through fertilization.

[0004] Therefore, in response to the above problems, there is an urgent need to develop a fertilization method that can improve the soil ecological environment of moso bamboo forests, increase the yield of bamboo shoots, enhance the quality of bamboo shoots, and reduce the amount of chemical fertilizers used to meet market and production demands. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a fertilization method for moso bamboo forests based on microbial hydrolysis small molecule fish peptide fertilizer, which addresses the shortcomings of the prior art. This method is based on environmentally friendly water-soluble organic fertilizer, which can increase the yield of moso bamboo shoots, improve the quality of bamboo shoots, reduce the amount of chemical fertilizer used, and improve the soil microenvironment.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a fertilization method for moso bamboo forests based on microbial hydrolysis of small molecule fish peptide fertilizer, the fertilization method comprising the following steps:

[0007] S1. Fertilizer preparation: Prepare a solution of microbial hydrolyzed small molecule fish peptide fertilizer using microbial hydrolyzed small molecule fish peptide fertilizer.

[0008] S2. Bamboo forest structure regulation: Before fertilization, new bamboo is retained and nurtured, and then the density of standing bamboo is controlled by selectively cutting old bamboo, and the age ratio of standing bamboo is regulated.

[0009] S3. Fertilization Management: Fertilization is carried out using the square trench fertilization method. Square fertilization trenches are dug around each bamboo tree, and fertilizer is applied in the square fertilization trenches. The first fertilization is carried out in late April, first applying the bacterial hydrolysate small molecule fish peptide fertilizer solution obtained in S1, and then applying compound fertilizer 3-5 days later, followed by soil covering. The second fertilization is carried out in early July, first applying the bacterial hydrolysate small molecule fish peptide fertilizer solution obtained in S1, and then applying compound fertilizer 3-5 days later, followed by soil covering.

[0010] Preferably, the bacterial hydrolysate small molecule fish peptide fertilizer solution in S1 is obtained by diluting the bacterial hydrolysate small molecule fish peptide fertilizer with water by 300 to 500 times.

[0011] Preferably, the number of new bamboo plants retained in S2 is 700 plants / hm². 2 ~750 plants / hm 2 The density of the upright bamboo was controlled at 2100 plants / hm². 2 ~2250 plants / hm 2 The age ratio of the standing bamboo is 1 degree bamboo: 2 degree bamboo: 3 degree bamboo = 1:1:1.

[0012] Preferably, the mass ratio of N, P2O5 and K2O in the compound fertilizer in S3 is 17:7:17.

[0013] Preferably, the method of opening a square fertilization trench in S3 is as follows: taking the bamboo culm as the center, set up two squares with side lengths of 120cm and 80cm respectively, and the area between the two squares is the fertilization area. One side of each of the two squares is parallel to the extension direction of the bamboo rhizome; dig a trench in the fertilization area with a depth of 20cm and a width of 20cm.

[0014] Preferably, in step S3, the microbial hydrolysate fish peptide fertilizer solution is applied by pouring the microbial hydrolysate fish peptide fertilizer solution into a square fertilization trench in the fertilization area; when applying the compound fertilizer, the compound fertilizer solid fertilizer is evenly spread into the square fertilization trench in the fertilization area, and the soil is backfilled after each fertilization.

[0015] Preferably, in S3, the first fertilization involves applying the microbially hydrolyzed small molecule fish peptide fertilizer solution at a rate of 60 kg / hm². 2 Apply compound fertilizer at a rate of 225 kg / hm² 3-5 days later. 2 The fertilizer application ratio for grade 1 bamboo, grade 2 bamboo, and grade 3 bamboo is 1:1:1; the fertilizer application ratio for preparing the bacterial hydrolysate small molecule fish peptide fertilizer solution is 4:15.

[0016] Preferably, in S3, the second fertilization involves applying the microbially hydrolyzed small molecule fish peptide fertilizer solution at a rate of 90 kg / hm². 2 Apply compound fertilizer at a rate of 150 kg / hm² after 3-5 days. 2 The fertilizer application ratio for grade 1 bamboo, grade 2 bamboo, and grade 3 bamboo is 7:9:9; the fertilizer application ratio for preparing the bacterial hydrolyzed small molecule fish peptide fertilizer solution is 9:15 for the bacterial hydrolyzed small molecule fish peptide fertilizer and the compound fertilizer.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] 1. Compared to uniformly spreading 750 kg / hm per year 2The existing fertilization methods for moso bamboo forests using compound fertilizers differ from those of the present invention. The new method can increase the yield of bamboo shoots by 59%, achieving a high yield. This invention utilizes a microbial hydrolysate peptide fertilizer rich in amino acids and organic matter to increase soil amino acid and organic carbon content, providing carbon and nitrogen sources for soil microorganisms, optimizing the microbial community structure, and increasing the number of microorganisms. This enhances the bamboo's ability to absorb nutrients. Furthermore, by applying appropriate amounts of compound fertilizer after the spring shoots (late April) and during the shoot growth period (early July), the nutrient content in the soil is further increased, significantly promoting nutrient absorption by the bamboo roots and shoot growth.

[0019] 2. Compared to uniformly spreading 750 kg / hm per year 2 The existing fertilization methods for moso bamboo forests using compound fertilizers differ from those of this invention. This invention reduces the amount of compound fertilizer used by 50% while increasing the yield of bamboo shoots. The main principles are as follows: First, this invention precisely determines the fertilizer ratio based on the different fertilization purposes in April and July, as well as the different mechanisms of action of the two fertilizers. This achieves higher fertilization effects with relatively less fertilizer. April to June is the critical period for new bamboo growth; therefore, the ratio of the first fertilization (using microbial small-molecule fish peptide fertilizer and compound fertilizer) is 4:15, setting a higher proportion of compound fertilizer to increase nutrient input and promote bamboo growth and material accumulation. July is the critical period for rhizome growth, so the ratio of the microbial small-molecule fish peptide fertilizer and compound fertilizer is set at 9:15, increasing the proportion of microbial small-molecule fish peptide fertilizer to promote rhizome extension and shoot growth. Second, based on the different growth-promoting purposes of the two fertilizations and the shoot-producing capacity of bamboo at different ages, the first fertilization is applied indiscriminately to promote the growth and material accumulation of bamboo at all ages. Because moso bamboo is a spreading bamboo, its underground rhizomes form a network that is interconnected. After nutrients are absorbed, some can be integrated and distributed through these rhizomes. Therefore, providing more fertilizer to grade 2 and grade 3 bamboo, which have higher nutrient absorption efficiency and shoot production rates, can greatly increase fertilization efficiency. This invention sets a 7:9:9 fertilization ratio for grade 1, 2, and 3 bamboo in the second fertilization to achieve the goal of "maximizing the use of the most efficient." Thirdly, a square trench fertilization method is adopted. Square trench fertilization areas are designed according to the distribution range of the moso bamboo root system and the direction of rhizome extension, promoting the foraging extension of the moso bamboo root system and reducing fertilizer loss. Through the above methods, fertilizer utilization efficiency is improved and the amount of chemical fertilizer applied is reduced. Due to the reduction in the amount of compound fertilizer applied and the increase in soil organic matter content, the residual amount of phosphorus in the soil is reduced, the pH of acidic soil increases, and the activity of soil enzymes such as urease, sucrase, and acid phosphatase increases, thereby improving the soil ecological environment and enhancing the suitability for moso bamboo growth.

[0020] 3. Compared to uniformly spreading 750 kg / hm per year 2The existing fertilization methods for moso bamboo forests using compound fertilizers differ from those of this invention. The new method reduces oxalic acid content in moso bamboo shoots by 6.3%, tannin content by 3.6%, lignin content by 20.22%, increases protein content by 6.6%, and increases soluble sugar content by 22.64%. The main principle is that the application of microbially hydrolyzed small-molecule fish peptide fertilizer increases the amino acid content in the soil. Amino acids can be directly or indirectly absorbed by the bamboo roots through chelation of trace elements, promoting protein synthesis and accumulation in bamboo and bamboo shoots. Combined with appropriate amounts of compound fertilizer, this promotes the absorption of nutrients such as nitrogen, phosphorus, and potassium by the bamboo, enhancing its photosynthetic capacity and the synthesis, transport, and accumulation of carbohydrates, effectively increasing the soluble sugar and cellulose content in the shoots. The application of organic matter in the fertilizer also improves the soil's acid-base environment, increasing the soil pH value, thereby reducing the accumulation of acids and tannins in the shoots and improving their taste and quality.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0023] Example 1

[0024] This embodiment describes a fertilization method for moso bamboo forests based on microbial hydrolysis of small molecule fish peptide fertilizer. The method includes the following steps:

[0025] S1. Fertilizer preparation: Prepare a solution of microbial hydrolysed small molecule fish peptide fertilizer using microbial hydrolysed small molecule fish peptide fertilizer. The composition and content of microbial hydrolysed small molecule fish peptide fertilizer are shown in Table 1.

[0026] S2. Bamboo Forest Structure Control: Select 1 mu of moso bamboo forest during a year with low bamboo shoot growth. Before fertilization, retain 49 new bamboo plants, and then control the standing bamboo density to 2205 plants / hm² by selectively cutting down older bamboo. 2 And control the age ratio of standing bamboo to be 1 degree bamboo: 2 degree bamboo: 3 degree bamboo = 1:1:1;

[0027] S3. Fertilizer Management: Fertilizer is applied using the square trench fertilization method. A square fertilization trench is dug around each bamboo culm. Centered on the bamboo culm, two squares with side lengths of 80cm and 120cm are set up, one inside and one outside. The area between the two squares is the fertilization area. One side of each square is parallel to the direction of the bamboo rhizome. Before fertilization, a trench with a width of 20cm and a depth of 20cm is dug in the fertilization area, and fertilizer is applied in the square fertilization trench.

[0028] The first fertilization was carried out in late April. 4 kg of microbial hydrolysate fish peptide fertilizer was diluted 500 times with water to obtain the microbial hydrolysate fish peptide fertilizer solution, which was then poured into square fertilization trenches for bamboo of different ages. The ratio of the amount of microbial hydrolysate fish peptide fertilizer solution for grade 1, grade 2, and grade 3 bamboo was 1:1:1. 3 to 5 days later, 15 kg of compound fertilizer was spread in the square fertilization trenches for bamboo of different ages. The ratio of the amount of compound fertilizer for grade 1, grade 2, and grade 3 bamboo was 1:1:1. Then, the soil was covered with soil to a depth of 25 cm.

[0029] In early July, a second fertilization was carried out. 6 kg of microbial hydrolysate fish peptide fertilizer was diluted 500 times with water to obtain a microbial hydrolysate fish peptide fertilizer solution, which was then poured into square fertilization trenches for bamboo of different ages. The ratio of the microbial hydrolysate fish peptide fertilizer solution for grade 1, grade 2, and grade 3 bamboo was 7:9:9. 3-5 days later, 10 kg of compound fertilizer was spread in the square fertilization trenches for bamboo of different ages. The ratio of the compound fertilizer for grade 1, grade 2, and grade 3 bamboo was 7:9:9. The soil was then covered with fertilizer to a depth of 25 cm. The N:P2O5:K2O ratio of the compound fertilizer was 17:7:17, and the total nutrient content was ≥45%. The shoots were harvested in large quantities from July to October.

The existing fertilization method involves evenly spreading 375 kg / hm² of fertilizer in May and August each year. 2 Compound fertilizer, total application rate is 750 kg / hm² 2 The results are shown in Table 2; it can be seen that the fertilization method in Example 1 greatly improved the number of bamboo shoots, the total yield, and the quality of individual bamboo shoots.
