Description

High-yield cultivation technology of rhubarb

Technical Field

The invention relates to a plant cultivation method, in particular to a rhubarb cultivation method.

Background

Rhubarb, also known as general, xiang da huang, u han huang, nan da huang, etc., is a perennial herb of the family Polygonaceae. The rhizome of underground herbs has the actions of purging and eliminating accumulation, clearing heat and purging fire, cooling blood and removing toxicity, removing blood stasis and dredging channels, promoting diuresis and removing jaundice. Can be used for treating constipation due to excessive heat accumulation, hematemesis, epistaxis, conjunctival congestion, pharyngeal swelling, carbuncle, furuncle, intestinal carbuncle, abdominal pain, blood stasis, amenorrhea, puerperal blood stasis, traumatic injury, damp-heat dysentery, jaundice, dark urine, stranguria, and edema; it can be used for external treatment of burn and scald. The wine rhubarb is good at clearing heat and toxicity in the upper jiao and blood system. It can be used for treating conjunctival congestion, pharyngeal swelling, and gingival swelling and pain. The cooked rhubarb has the functions of relieving the purgation, purging fire and removing toxicity. It can be used for treating pyocutaneous disease due to fire toxin. Rhubarb charcoal cools blood, removes stasis and stops bleeding. Can be used for treating blood heat with blood stasis and hemorrhage. Wild rhubarb grows dispersedly, and after being mined for many years, wild resources are less and less, the wild rhubarb is difficult to collect, and the wild rhubarb has low yield and uneven quality and is difficult to meet the increasing market demand. Therefore, it is necessary to explore a complete and scientific cultivation method for rhubarb.

3. performing field management, after the rhubarb seedlings are aligned, intertillage and weeding are performed, the condition that no weeds exist on the surface of a furrow is ensured, watering is performed in time in dry weather, water drainage is paid attention to in rainy weather, and topdressing is performed for 1 time before and after beginning of autumn; applying 20kg of urea and 10kg of monopotassium phosphate per mu, easily performing bolting and flowering in 2-3 years after the rheum officinale is transplanted, and removing flower moss as soon as possible except for reserved plants;

4. pest control, a, root rot: 1: 1: 100 Bordeaux mixture prevention and control; or the 65 percent mancozeb is used for preventing and treating the diseases in the early stage of the disease; B. downy mildew: lead fosetyl-phosphate or carbendazim is generally used for prevention and treatment in the early stage of onset of disease. C. The pests mainly comprise aphids and can be controlled by methamidophos, and the underground pests are controlled by phoxim and carbofuran;

5. harvesting and processing, wherein the rhubarb is generally harvested in time after seeds are mature in autumn of 3-4 years after planting, and during harvesting, overground stem leaves are firstly cut, underground rhizome and stems are dug out, soil is removed, and the rhubarb can be used as a medicine for sale after being dried in the sun.

The yield per mu of the rhubarb cultivated by the rhubarb cultivation method reaches 5000 kilograms, the quality of the produced medicine is high, the medicine is uniform, and the yield is ensured.

Detailed Description

Embodiment 1, a method for cultivating astragalus membranaceus comprises the steps of selecting land, preparing land, fertilizing, sowing, managing the field, preventing and treating diseases and insect pests, harvesting and processing; the method comprises the following steps:
