Problems solved by technology

[0003] As a famous authentic medicinal material in Zhejiang Province, Wen Yu Jin has a long history of planting. Only Taoshan Town, Ruian City has a planting history of nearly 1,000 years. Self-propagation and self-retaining lead to the mixing and aging of plants, and no research on the breeding of fine new varieties has been carried out. In addition, the phenomenon of continuous cropping is very common, and many people have been planted continuously for more than 5 to 6 years, resulting in the following problems:
[0004] (1) Curcuma curcuma has poor stress resistance, germplasm degradation and plant virusization are serious;
[0005] (2) The production reduction is as high as 40%, and the serious production reduction reaches more than 50%, which has caused huge economic losses to local farmers;
[0006] (3) The good and bad among plants are uneven, the quality varies greatly, and the content of active ingredients is low, resulting in unstable quality of medicinal materials, which seriously affects the effectiveness and safety of clinical medication;

Embodiment approach

[0034] According to a preferred embodiment of the present invention, the base fertilizer includes bar manure, preferably decomposed bar manure.

[0035] In the present invention, the bar manure refers to the manure made mainly of livestock manure mixed with various gasket materials, and the decomposed bar manure refers to the bar manure after being fully fermented.

[0036] The inventors have found that the various fertilizers in the manure are mostly in an organic state, and the plants cannot directly absorb them. They need to be fermented to decompose the organic matter into inorganic salts that can be absorbed by the plants; the manure contains a large amount of bacteria and insect eggs. The high temperature can kill most bacteria and insect eggs; apply non-fermented bar fertilizer, the high temperature generated by its own fermentation may burn the root system of the plant.

[0037] In a further preferred embodiment, the base fertilizer also includes microbial bacterial li...

[0131] (1) Site selection and preparation:

[0132] Select an area with an annual average temperature of 17°C, an annual minimum temperature of -2°C, an average relative humidity of 83%, an annual rainfall of 1550mm, an annual sunshine of 1680h, and a frost-free period of 230d. The soil is sandy loam, slightly acidic, and the previous crop is rice. well drained;

[0133] Land preparation was carried out on March 20, the land was plowed 25cm deep, raked finely, and 5000kg / hm was applied 2 base fertilizer, the weight ratio of decomposed bar fertilizer, microbial bacterial liquid and vermiculite powder in the base fertilizer is 5:3:3, wherein, the microbial bacterial liquid is obtained after mixed culture and fermentation of nitrogen-fixing bacteria, yeast and Bacillus megaterium the bacterial liquid;

[0134] After mixing the base fertilizer, build a single row of furrows, the base of the furrow is 95cm wide and 30cm high, and the furrow surface gradually narrows to 30cm wide....

Abstract

The invention discloses a curcuma wenyujin elite breeding method. The method comprises the steps of land selection and preparation, seed selection and sowing, field management, purification and rejuvenation, harvesting and seed selection, storing and transportation, wherein a region suitable for curcuma wenyujin to grow is selected for planting, base fertilizer is added in the land preparation process, the sowing time and harvesting time are shortened and standardized, early weed suppression is conducted in the mode of covering steam leaves and mulching film, the yield of curcuma wenyujin seeds is significantly increased, the quality of the curcuma wenyujin seeds is significantly improved, and the content of effective components is increased.

Description

technical field [0001] The invention belongs to the technical field of medicinal plant breeding, and in particular relates to a method for breeding special-purpose warm turmeric varieties. Background technique [0002] Curcuma wenyujin (Curcuma wenyujin) is a plant of the genus Curcuma longa in the Zingiberaceae family. It is mainly produced in Ruian County and Yueqing County in Wenzhou, Zhejiang Province. It is one of the famous authentic medicinal materials in Zhejiang Province.
