TECHNICAL FIELD

[0001] The present application relates to a kind of apocynum venetum cultivation method and special growth aid. BACKGROUND

[0002] Apocynum venetum is a perennial herb, and the leaf of apocynum venetum has the effects of clearing heat and soothing liver, promoting water and reducing swelling. Moreover, as bast fiber plants, apocynum venetum fibers have high fiber content and high fiber strength, and have great utilization value. Apocynum venetum fibers have the effect of emitting far infrared rays, have the luster of silk, the stiffness of hemp, the flexibility of velvet, and the softness of cotton, have the advantages of bacteriostasis, deodorization and mildew resistance, have good air permeability, strong hygroscopicity, softness, bacteriostasis, winter warmth and summer coolness, and can be spun into high-quality shirts, underwear and home accessories, etc.

[0003] However, in the current apocynum venetum planting, the utilization of apocynum venetum leaves is sufficient, but the utilization of apocynum venetum bark is very limited. One of the important reasons is that the apocynum venetum bark is difficult to peel off, whether fresh or dry, and it is difficult to separate the apocynum venetum bark from the stem. The main reason is that the apocynum venetum bark is tightly adhered to the wooden stem, and the apocynum venetum bark and fiber are tightly adhered to the apocynum venetum stem. Apocynum venetum cannot be peeled off like normal ramie and other varieties of hemp, which greatly reduces the economic benefits of large-scale apocynum venetum planting.

[0004] The difficulty in separating the apocynum venetum bark from the stem is the biggest obstacle to the utilization of apocynum venetum bark in apocynum venetum planting. At present, there is no suitable method for peeling off the apocynum venetum bark. SUMMARY

[0005] The present application aims to provide an apocynum venetum planting method and a special growth aid, so that not only apocynum venetum leaves can be obtained, but also the characteristics of apocynum venetum bark and stem can be changed, especially the structure between apocynum venetum bark and stem can be changed to facilitate peeling off the apocynum venetum bark from the stem.

[0006] The purpose of the present application is achieved by the following technical solutions.

[0007] In the first 100 days of apocynum venetum growth and germination of 10-30 cm height, water is poured 3-4 times per month, and among the 3-4 times of watering per month, fertilization is selected once with watering: 5-12 kg / acre of urea and 3-5 kg / acre of potassium dihydrogen phosphate are applied each time, and 2-4 days after fertilization with watering, growth aid is applied once, and the growth aid is sprayed on the apocynum venetum plants.

[0008] The growth aid is diluted and uniformly sprayed on the front and back of the apocynum venetum plants to a dripping state, and the apocynum venetum plants are sprayed at least 3 times during the growth period.

[0009] The growth aid contains the following substances: naphthalene acetic acid 0.5-1 parts by weight, fulvic acid 2-3 parts by weight, titanium dioxide 2-3 parts by weight, and seaweed extract 1-2 parts by weight.

[0010] Further, the seaweed extract is preferably seaweed hydrolysate or seaweed fermentation liquor.

[0011] When used, the growth aid is diluted 300-500 times in water and sprayed, 20-70 kg / mu.

[0012] Further, the watering is preferably drip irrigation, and the fertilization with watering is drip irrigation fertilization.

[0013] Further, a shading net is used to shade during the growth period of apocynum venetum, and the light transmittance is maintained at 40-60%.

[0014] Further, the height of the shading net is preferably 180-220 cm.

[0015] The advantages of the present application are that not only can apocynum venetum leaves with higher chlorophyll and effective ingredient content and better quality be obtained, but also the adhesion degree of apocynum venetum bark and stem can be effectively reduced, so that the bark can be easily peeled off from the stem, the peeling difficulty of apocynum venetum is effectively reduced, the utilization rate of apocynum venetum bark is improved, and the economic benefits of large-scale planting of apocynum venetum are greatly improved.
