Problems solved by technology

[0005] Excessive chemical fertilizers have limited effect on crop yield increase. Excessive application of chemical fertilizers will not only lead to low fertility utilization, but also the higher the amount of chemical fertilizers, the greater the damage to the basic fertility of the soil. This is not only harmful to the soil and the environment. It also threatens food security
Excessive use of chemical fertilizers will increase crop pests and diseases, thereby increasing the use of pesticides, resulting in more pesticide residues
However, relying solely on organic fertilizers not only requires a large amount of fertilizer, but also results in low crop yields.

Embodiment 1

[0024] A method for ecological cultivation of Houttuynia cordata, specifically comprising the steps of:

[0025] 1) Land plot selection: In February, select sandy loam land plots that are flat, have sufficient water sources, convenient drainage and irrigation, deep plowing layer, suitable soil structure, good physical and chemical properties, and moderate fertility; thoroughly remove weeds and previous crops, and deeply plow and harrow , so that the land is loose, fertile and flat;

[0026] 2) Planting: Apply 1000kg of decomposed farmyard manure, 20kg of compound fertilizer and 100kg of kelp residue per mu, plow and plow to a depth of 25-30cm to make a flat furrow with a width of about 150-160cm. 40×8-10cm buried stems;

[0027] Kelp slag is processed through the following steps:

[0028] ①Raw material processing: smash the dried kelp;

[0029] ②Water extraction treatment: add 10 times the weight of water to the crushed kelp, decoct once, 2 hours each time;

[0030] ③Ultra...

Embodiment 2

[0035] 1) Land plot selection: In March, select sandy loam land plots that are flat, have sufficient water sources, convenient drainage and irrigation, deep plowing layer, suitable soil structure, good physical and chemical properties, and moderate fertility; thoroughly remove weeds and previous crops, and deeply plow and harrow , so that the land is loose, fertile and flat;

[0036] 2) Planting: Apply 800kg of decomposed farmyard manure, 25kg of compound fertilizer and 80kg of kelp slag per mu, plow and plow to a depth of 25-30cm to make a flat furrow with a width of about 150-160cm. 40×8-10cm buried stems;

[0037] Kelp slag is processed through the following steps:

[0038] ①Raw material processing: smash the dried kelp;

[0039] ②Water extraction treatment: add 15 times the weight of water to the crushed kelp, decoct twice, 1 hour each time;

[0040] ③Ultrasonic treatment: decoction to obtain the solution and slag, ultrasonic treatment for 5-10 minutes, the action tempe...

Abstract

The invention discloses an ecological cultivation method of herba houttuyniae. The ecological cultivation method comprises the following steps: selecting a land block, planting, performing field management and harvesting. According to the ecological cultivation method disclosed by the invention, kelp which is rich in resources in China is adopted as a fertilizer for cultivating herba houttuyniae; the kelp is used as the fertilizer, but the fishy smell of the kelp can not affect the taste of herba houttuyniae, so that the use application of the kelp is developed; compared with the prior art, the using amount of the fertilizer is reduced in the cultivation process by using the method; simultaneously, the process steps are simple, and the labor amount is reduced.

Description

technical field [0001] The invention relates to the technical field of nursery stock cultivation, in particular to an ecological cultivation method of houttuynia cordata. Background technique [0002] Houttuynia cordata, English name HERBA HOUTTUYNIAE, is a herbal medicine included in the Chinese Pharmacopoeia. The source of the herbal medicine is the dry aerial part of the plant Houttuynia cordata Thunb. In summer, when the stems and leaves are lush, the flowers and spikes are often harvested, removed from impurities, and dried in the sun. Herbal traits: The stem is oblate and cylindrical, twisted, 20-35cm long, and 0.2-0.3cm in diameter; the surface is brownish yellow, with several longitudinal ribs, obvious nodes, and residual fibrous roots on the lower nodes; brittle and easy to break. Alternate leaves, curled and shrunken, heart-shaped after flattening, 3-5cm long, 3-4.5cm wide; apex acuminate, entire margin; upper surface dark yellow-green to dark brown, lower surface...
