Embodiment 1

[0011] A high-yield cultivation method of Polygonum cuspidatum, the method steps to realize this scheme are as follows:

[0012] (1) Breeding and raising seedlings: Before the plants germinate in spring, cut the mother plant and cut the rhizomes into 15-20 cm sections, with 70 cm row spacing, 8 cm deep grooves, and 2 rhizomes placed every 40 cm. , Cover soil compaction. And pour water on the ground to moisturize the soil.

[0013] (2) Planting at selected sites: When transplanting and planting, the plant spacing is 40cm. Dig a 10 cm deep nest on the planting, then put the seedlings into the nest, cover with soil and compact. And spray water on it to fix roots and moisturize.

[0014] (3) Seedling selection and thinning: thinning is carried out when the plant seedling is 10 cm high, leaving vigorously growing seedlings and 2 strong seedlings per hole.

[0015] (4) Spray formula fertilizer: 3 parts of rare earth nutrient solution, 1 part of organic selenium-enriched fertilizer, 2 par...

Embodiment 2

[0017] (1) Breeding and raising seedlings: Before the plants germinate in spring, cut the mother plant and cut the rhizomes into 15-20 cm sections, with 70 cm row spacing, 8 cm deep grooves, and 2 rhizomes placed every 40 cm. , Cover soil compaction. And pour water on the ground to moisturize the soil.

[0018] (2) Planting at selected sites: When transplanting and planting, the plant spacing is 40cm. Dig a 10 cm deep nest on the planting, then put the seedlings into the nest, cover with soil and compact. And spray water on it to fix roots and moisturize.

[0019] (3) Seedling selection and thinning: thinning is carried out when the plant seedling is 10 cm high, leaving vigorously growing seedlings and 2 strong seedlings per hole.

[0020] (4) Spray formula fertilizer: spray the rare earth nutrient solution aqueous solution every 13 days after planting. The rare earth nutrient liquid fertilizer aqueous solution is obtained by uniformly mixing 7 parts of rare earth nutrient liquid...

Abstract

The invention provides a high-yield cultivation method for Polygonum cuspidatum. The high-yield cultivation method mainly comprises spraying a formula fertilizer, and the formula fertilizer is made by 3 to 7 parts of rare earth nutrient solution, 1 to 3 parts of organic selenium-rich fertilizer, 2 to 6 parts of nursery stock quickly-growth and thickening agent, 3 to 8 parts of rhizome expanding agent, and 2000 to 3000 parts of water, the above components are uniformly mixed to make the formula fertilizer and then the formula fertilizer is sprayed. By adopting the above technical scheme, the chlorophyll content of Polygonum cuspidatum leaves and photosynthesis of the Polygonum cuspidatum leaves are raised; growth and development of Polygonum cuspidatum roots are promoted, adoption and circulation of nitrogen, phosphor and potassium, and medium trace elements in the Polygonum cuspidatum roots are promoted, and the utilization rate of the fertilizer can be raised; the drought resistance, the continuous cropping resistance and the disease resistance of the Polygonum cuspidatum are raised; and compared with the prior art, the yield of the Polygonum cuspidatum cultivated by the method in 250 mu test filed is raised by more than 20 %.

Description

Technical field [0001] The invention relates to the field of Chinese herbal medicine cultivation, in particular to a high-yield cultivation method of Polygonum cuspidatum. Background technique [0002] Chinese herbal medicine has a long history in our country, and it has played a positive role in the prosperity of the Chinese nation. The great leader Mao Zedong said: "Chinese herbal medicine is the treasure of the Chinese nation. It must be rectified, explored and improved." The Chinese herbal medicine is conducive to social development and human progress. [0003] Polygonum cuspidatum is bitter in taste and slightly cold in nature. It has the effects of dispelling wind and dampness, diuresis and leaching, clearing heat and detoxification, promoting blood circulation and removing blood stasis. The fresh and tender stems and leaves of Polygonum cuspidatum are edible. Resveratrol extracted from Polygonum cuspidatum is one of the anti-aging substances. Because Polygonum cuspidatum ...
