Description

Technical Field

[0001] The invention belongs to the technical field of bamboo shoot cultivation, and particularly relates to a high-efficiency bamboo shoot cultivation method. Background Art

[0002] Bamboo shoots are the young shoots of the underground stems of bamboo. They are a kind of food with high nutritional value. They are rich in nutrients such as protein, amino acids, fat, carotene, dietary fiber, vitamins and minerals. They have the effects of relieving constipation, promoting digestion, diuresis and swelling, and lowering blood lipids. There are many types of bamboo shoots, which are widely distributed in all continents, especially in tropical, subtropical and temperate regions.

[0003] As a green food, bamboo shoots have an increasing market demand as people's quality of life improves and wild resources decrease. Although the traditional application of chemical fertilizers can increase the yield of bamboo shoots, the widespread use of chemical fertilizers has caused varying degrees of impact on the soil in the planting area, such as soil quality decline, soil acidification and soil compaction. Microbial fertilizers are developed based on the principles of soil microecology, plant nutrition and the basic concepts of modern organic agriculture. They are a new type of fertilizer biological product that produces nutrients required by crops through the life activities of active and reproducible microorganisms. They are a type of fertilizer in agricultural production. Therefore, seeking a microbial fertilizer suitable for bamboo shoot cultivation is of great significance to the efficient cultivation of bamboo shoots and the green and healthy development. Summary of the invention

[0004] The purpose of the present invention is to provide a method for efficiently cultivating bamboo shoots, which applies microbial fertilizer in holes during the bamboo shoot planting process, helps to increase the yield of bamboo shoots, and is of great significance to the efficient cultivation and green and healthy development of bamboo shoots.

[0005] To achieve the above object, the present invention provides the following technical solutions: A method for efficiently cultivating bamboo shoots comprises the following steps: S1. Transplanting bamboo seedlings In mid-March each year, select strong mother bamboos with full buds at the base of the culms, dig them out and transplant them to the planting area at a spacing of 0.5m×1m, and water them thoroughly. S2. Field management In late March every year, microbial fertilizer is applied to the holes. The microbial fertilizer is composed of the following components, measured in parts by weight: 40-50 parts of biochar, 12-15 parts of calcium hydrogen phosphate, and 8-10 parts of microbial agent; wherein the microbial agent is composed of Bacillus jelly-like (BNCC132700), Nitrogen-fixing Bacillus brown (BNCC192292) and Alcaligenes faecalis subsp. faecalis (BNCC186100).

[0006] More specifically, in step S2, the amount of fertilizer applied is 0.5-1 kg / plant.

[0007] More specifically, in step S2, the method for preparing the biochar is as follows: the corn stalks are cleaned and dried to constant weight, cut into stalk segments of 2-3 cm, placed in a biogasifier, anaerobic cracked at 350° C. for 4 hours, cooled to room temperature, ground and crushed, and passed through an 80-120 mesh sieve to obtain the biochar.

[0008] More specifically, in step S2, the number of live bacteria in the jelly-like Bacillus was 6.2×10 8 The number of viable bacteria in the brown ball nitrogen-fixing bacteria is 1.4×10 8 The number of viable bacteria in Alcaligenes faecalis subsp. faecalis was 3.8×10 8 Pieces / g.

[0009] More specifically, in step S2, the mass ratio of Paenibacillus gelatinosa, Azotobacter nitrofusus and Alcaligenes faecalis subsp. faecalis in the microbial agent is 1:3:3.

[0010] Compared with the prior art, the present invention has the following beneficial effects: The present invention applies a microbial fertilizer composed of biochar, calcium hydrogen phosphate and a microbial agent during the bamboo shoot planting process. Through experiments, it was found that the application of jelly-like Bacillus, brown ball nitrogen-fixing bacteria or Alcaligenes faecalis subspecies can increase the weight of a single bamboo shoot; and when the three are used in combination of two or three, the weight of a single bamboo shoot can be further increased. Among them, when jelly-like Bacillus, brown ball nitrogen-fixing bacteria and Alcaligenes faecalis subspecies are applied at the same time, the increase in the weight of a single bamboo shoot is better than the effect of using them in combination of two. When the three are used in combination at a mass ratio of 1:1:3, the weight value of a single bamboo shoot is the largest. Applying the microbial fertilizer of the present invention in holes during the bamboo shoot cultivation process helps to increase the yield of bamboo shoots, which is of great significance to the efficient cultivation and green and healthy development of bamboo shoots.
