Problems solved by technology

The problem that this method exists is: (1) Maca can only be planted in high altitude (> 2500 meters) area, and the land resource suitable for planting Maca in my country's high altitude area is limited, has had a strong impact on the enlargement of my country's Maca cultivation area and The increase of total output; (2) the problem of planting maca in autumn and harvesting in spring at low altitudes (<2000 meters) has not been solved. A large amount of land in low altitude areas is idle in winter, and the land utilization rate and output value are low, which is not conducive to the production of maca in my country. The expansion of the cultivation area of ​​maca and the improvement of yield; (3) the problem that the cultivation of maca needs to be rotated is not solved
Although these patents provide methods for planting maca in spring and harvesting in autumn and winter in high-altitude (>2500 meters) areas, they fail to solve the problem of planting maca in autumn and harvesting in spring in low-altitude (<2000 meters) areas

Embodiment 1

[0025] The invention discloses a low-altitude autumn cultivation method for maca. The method includes technical links such as water cultivation of maca seedlings in greenhouses, low-altitude autumn transplanting, winter field film covering, and spring strong root harvesting. The technical points of each link are as follows:

[0026] 1. Water-cultivated seedlings in greenhouses: seed seedlings in June-August, fill the seedling tray with nutrient soil for seedling cultivation (peat: farmyard manure: vermiculite: perlite mass ratio = 2:2:1:1), vibrate and compact; seedlings The length and width of the tray is 40-50cm×80-100cm, with holes at the bottom; the number of holes in the seedling tray is 100-200, the hole depth is 5-6cm, and 1-3 seeds are sown in each hole, and then covered with a layer of nutrient soil for seedling cultivation, with a thickness of 0.2-0.5 cm, put the seedling tray in the pool of the greenhouse, the water depth of the pool is 2-3cm; add food-grade hydrogen...

Embodiment 2

[0031] The invention discloses a low-altitude autumn cultivation method for maca. The method includes technical links such as water cultivation of maca seedlings in greenhouses, low-altitude autumn transplanting, winter field film covering, and spring strong root harvesting. The technical points of each link are as follows:

[0032] 1, greenhouse hydroculture seedling: with embodiment 1.

[0033] 2. Transplanting in autumn at low altitude: choose a hilly area with an altitude of 500 meters to plant maca, and the transplanting time is mid-September; 200 mu of cultivated land is leveled, the soil pH is 5.5-7.5, and the field is turned twice before transplanting Plowing, the first deep plowing and exposure in the first ten days of August, and the second plowing in early September. Before the second plowing, apply 400kg of humic acid raw powder per mu and mix 2000kg of decomposed farmyard manure, and then use 30% humic acid Dilute the soil with 100L of hydrogen peroxide and steril...

Abstract

The invention provides a low altitude autumn culture method for Maca. The method comprises greenhouse water culture for seedlings of the Maca, low altitude autumn planting, winter field film covering, spring strong root harvesting and other technique processes. According to the low altitude autumn culture method for the Maca, the Maca can be cultured in low altitude mountain and hilly areas which are below 2000 m, the culture area of the Maca all over the country is significantly enlarged, and the total output of the Maca is improved; by means of the method of culturing the Maca in autumn and harvesting the Maca in spring, a great number of vacant fields in winter are utilized, agriculture land utilization ratio and output value are improved, and meanwhile the problems of crop rotation of the Maca culture and spring market supply are solved; winter field management adopts films to cover the field, the temperature, the temperature difference and the photosynthesis which are needed by the growth of the Maca are increased, the output and the quality of the Maca are significantly improved, and good economic benefit is brought. Accordingly, the low altitude autumn culture method for the Maca has wide utilizing and popularizing value for Maca culture in the low altitude mountain and hilly areas which are below 2000 m in our country.

Description

technical field [0001] The invention belongs to the technical field of planting economic crops, and in particular relates to a method for cultivating Maca in low-altitude autumn, in particular to a method for cultivating Maca in low-altitude areas below an altitude of 2000 meters. Background technique [0002] Maca (Lepidium meyenii Walp.), known as Maca in English, is a 1-year or 2-year-old herb of the Cruciferae genus Lepidium. It is also known as "Peruvian Ginseng ( Peruvian ginseng)". The main part of Maca is the root. Its root is fleshy, short conical, like a radish, and its outer skin is often yellow, white and purple. It is not only rich in carbohydrates, protein, various amino acids, unsaturated fatty acids ( Linoleic acid and α-linolenic acid), a variety of minerals (K, Ca, Fe, Zn) and a variety of vitamins (VB1, VB2, VB3, VB6, VB12 and VC) and other nutrients, also contains unique active ingredients ——Macamide and Maceaene, as well as active substances such as gl...
