Problems solved by technology

At present, the growers in the main producing area of ​​Pengezhu are still planting according to the traditional extensive mode, without scientific and technological guidance, and there are many irregularities in each production link. The main problems are as follows: (1) Long-term asexual reproduction And the self-propagation and self-retention of the provenance lead to the aging of the ginger, the lack of quality standards for the ginger, and the continuous cropping phenomenon is very common, resulting in the degradation of the warm curcuma variety, poo

Embodiment 1

[0027] Upper and lower field experimental research

[0028] Table 1 Yield results of green silk turmeric in the field experiment (n=3)

[0029]

[0030] Table 2 The total curcumin detection results (n=3) of the comparison experiment between upper and lower fields

[0031]

[0032] Summary: There is no significant effect on the yield of green silk turmeric in Shangxiatian, and there is almost no difference in the yield of upper and lower fields; the total curcumin test results show that the content of green silk turmeric in lower field is higher than that in upper field, so green silk turmeric should be planted in Xiatian.

Embodiment 2

[0034] Fertilizer Experimental Research

[0035] Table 3 Yield results of green silk turmeric fertilizer experiment in Zhoudu base (n=3)

[0036]

[0037] Table 4 Experimental output results of green silk tulip fertilizer in Wandang Base (n=3)

[0038]

[0039]

[0040] Table 5 Fertilizer experiment total curcumin detection result (n=3)

[0041]

[0042] Summary: Fertilizer has no significant effect on the yield of green silk turmeric produced in Zhoudu, but it has a very significant impact on the yield of green silk turmeric produced in Wandang. The optimal level is basically both superphosphate and Youku. One, the worst level is blank; and the test results of total curcumin show that the total curcumin content of each level is blank > superphosphate > medicinal material flourishing > oil dry > phosphorus and potassium fertilizer, so it is advisable to choose superphosphoric acid Calcium as fertilizer.

Embodiment 3

[0044] 1. Site selection

[0045] It is advisable to choose the crop rotation land that has not been planted in the previous year. It is best to choose loose, fertile, sandy loam with deep soil layers, and light clay is also acceptable. The soil pH is neutral or slightly acidic.

[0046] 2. Land preparation

[0047] Shallowly plow the ground 20-25cm in spring.

[0048] 3. Sowing period

[0049] The suitable sowing period of Ezhu is from May 20th to May 30th in the natural year.

[0050] 4. Seeding density

[0051] The planting density of Ezhu is 0.45-0.50m, and the number of plants per mu is 2700-3300;

[0052] 5. Ginger preparation

[0053] Before sowing, choose straight rhizomes with a diameter of more than 20mm and a length of more than 50mm, such as two heads and three heads, or large gingers with a diameter of more than 15mm and a length of more than 70mm as ginger, and rhizomes that are bruised and moldy cannot be used as ginger.

Abstract

The invention discloses a high quality and yield culture technology of curcuma zedoaria, which comprises the following steps: land selection and preparation, seed curcuma preparation, sowing, field management, harvesting and prevention and cure of plant diseases and insect pests. The technology of the invention is characterized in that: the rotation land or clay with neutral PH or micro acid in which curcuma zedoaria is not planted in the previous year is selected; prior to sowing, the rootstalk with two or three heads which has a diameter of more than 20mm and a length of more than 50mm, or a big curcuma which has the diameter of more than 15mm and the length of more than 70mm is selected as the seed curcuma, and the seed curcuma is sowed from May 20 to May 30 in a normal year; the planting density is 2700-3300 plants per mu with the row spacing of 0.45-0.50m; during sowing, fossias are dug in field, sowing is carried out according to the planting spacing of 0.45-0.50m. The bottom fertilizer is applied in the space between seed curcumas, and covering soil is carried out. The technology can improve the yield of the medicinal materials of zedoary root and radix curcume longae produced by curcuma zedoaria by 15%-20%, increase the content of curcuminoids, the content of germacrone, the content of naphtha by 15%-20%, 16%-20% and 10%-15% respectively, and increase the economic benefit by 15%-20%.

Description

technical field [0001] The invention relates to a high-quality and high-yield cultivation technology of Edoctoria fragrans, including processes such as site selection, site preparation, seed selection, sowing, fertilization, fine field management, reasonable planting mode, and scientific pest control measures. Background technique [0002] The original plant of Ezhu is Zingiberaceae Curcuma, which has a long history of planting in Shuangliu, Chongzhou and other areas of Chengdu for hundreds of years. Its rhizome is called Chuanzezhu (also known as Wenshu) in medicinal materials, and its root is called green silk turmeric in medicinal materials. Traditionally, it is better to have solid quality, fine skin wrinkles, and yellow cross-section. The 2005 edition of Pharmacopoeia only stipulates the measurement of moisture, and there is no specific evaluation index. The present invention uses total curcumin, curcumin and volatile oil as evaluation indexes. Ezhu has the functions o...
