Description
Technical Field
The invention relates to the technical field of traditional Chinese medicine seedling raising, in particular to a method for improving domestication survival rate and growth rate of seedling of Xian Mao Zupei.
Background
Rhizoma Curculiginis (Cruculigo orchioides Gaertn.) is plant of Curculigo belonging to Amaryllidaceae, has effects of invigorating kidney yang, strengthening tendons and bones, and dispelling dampness and cold, and is mainly used for treating sexual impotence, cold sperm, flaccidity of tendons and bones, lumbago, knee pain, yang deficiency, diarrhea, etc.
Along with the increase of the market demand of curculigo medicinal materials, the wild resources of curculigo are collected and increased year by year, so that the wild resources of curculigo are increasingly reduced, and meanwhile, as wild curculigo Mao Yiban grows under the forest, the wild resources may cause the damage of the root system of the forest and the water and soil loss when being collected and dug, so that the ecological environment is damaged. In recent years, artificial planting has gradually become a trend and is initially scaled up.
Because the curculigo seed is difficult to collect, the seed germination rate is extremely low, the seed quantity is small, and the like, the seedling of the curculigo Mao Zupei becomes the immortal Mao Chongmiao to obtain the most important propagation mode, and the technical development and production of the seedling of the curculigo Mao Zupei are carried out in the early stage of the team, but the root rot and the leaf water stain and serious are found in the domestication and seedling hardening process of the seedling of the curculigo Mao Zupei, the survival rate can only reach about 40% at most, and the leaf is dehydrated within 1-2 days when the moisture of the small arch is not adopted, the survival rate can reach about 60%, but even if the surviving seedling of the curculigo Mao Miao is withered, the new leaf can be sent out in 20-30 days, the domestication period of the seedling of the curculigo Mao Zupei is prolonged for at least 3-4 months, the seedling raising cost is increased, and the large-scale curculigo is unfavorable for raising seedlings.
Disclosure of Invention
The invention aims to provide a method for improving the domestication survival rate and the growth rate of the seedling of Xian Mao Zupei, which solves the problems of high death rate and long growth period in the process of cultivating tissue culture seedlings.
In order to achieve the above purpose, the invention adopts the following technical scheme:
the invention provides a nutrient solution for improving domestication survival rate of seedling of Xian Mao Zupei, which is at least one of nutrient solution A, nutrient solution B or nutrient solution C,
the nutrient solution A comprises the following components: 25-40 mg/L methyl jasmonate and 20-30 mg/L naphthylacetic acid;
the nutrient solution B comprises the following components: 80-120 mg/L methyl jasmonate and 40-60 mg/L naphthylacetic acid;
the nutrient solution C comprises the following components: 80 to 120mg/L of naphthylacetic acid, 20 to 30mg/L of kinetin, 1.0 to 1.5g/L of monopotassium phosphate and 0.5 to 1.0g/L of alginic acid.
The invention also provides a method for improving the domestication survival rate of the seedling of the Xian Mao Zupei, which comprises the following steps:
(1) Cleaning a basal culture medium of the seedling of the Chinese character Xian Mao Zupei, and planting the culture medium in a mixed matrix, wherein the mixed matrix is formed by mixing coconut husk, humus soil and garden soil according to a mass ratio of 3:3:5;
(2) After planting, spraying nutrient solution A on the leaves according to the usage amount of 30-40 kg per mu, and building a small arch shed for moisturizing after spraying;
(3) After 10-15 days of planting, spraying the nutrient solution B on the leaves according to the usage amount of 30-40 kg per mu;
(4) After planting for 25-35 days, spraying a nutrient solution C on the leaves according to the usage amount of 30-40 kg per mu;
(5) At 45 days after planting, the small arch shed is completely uncovered, and 0.1% of water-soluble compound fertilizer is poured and applied once every 15 days; the compound fertilizer N: p: k=15:15:20.
The beneficial technical effects achieved by the invention are as follows:
1. according to the invention, the domestication matrix adopts the mixed matrix of coconut husk, humus soil and garden soil in a ratio of 3:3:5, so that on one hand, the contradiction between air and moisture in the matrix can be solved to the greatest extent, the base part has enough moisture supply during domestication of the seedling Mao Zupei, meanwhile, oxygen deficiency caused by excessive moisture can be avoided, and the occurrence of root rot in the domestication process of the seedling Mao Zupei can be reduced to a certain extent.
2. In the domestication process of the seedling of the curculigo orchioides Mao Zupei, nutrient solution A and nutrient solution B are sprayed in the initial stage of domestication, nutrient solution C with a certain concentration is sprayed in the early stage of domestication, the domestication survival rate of the seedling of the curculigo orchioides Mao Zupei can be improved to more than 95%, and the mechanism is hypothesized that the methyl jasmonate can effectively induce the closing of pores of the seedling of the curculigo orchioides Mao Shepian in the initial stage, so that the transpiration effect of leaves is reduced, the stress reaction of the seedling of the curculigo orchioides Mao Zupei to drought stress is induced, and the naphthylacetic acid can promote the growth of the root system of the curculigo orchioides, so that the root system absorption capacity is increased, the growth of the seedling of the curculigo orchioides is regulated, the absorption capacity of the nutrient components of the curculigo orchioides is enhanced, and then potassium dihydrogen phosphate with a certain concentration and alginic acid are matched, so that the seedling of the curculigo orchioides Mao Miao can grow fast, and the seedling is more robust, and the seedling of the stress resistance to hypoxia, water shortage, root rot and the seedling is enhanced.
3. According to the invention, the corresponding nutrient solution is sprayed on the leaf surfaces within 30 days before domestication of the curculigo orchioides, so that the problem of leaf withering is avoided, the occurrence of root rot is reduced, the curculigo orchioides Mao Xunsu is promoted to be converted from heterotrophic into autotrophic and nutrient is accumulated, so that the formation of fleshy roots at the base of the stems is accelerated, and the sprayed nutrient solution has certain nitrogen, phosphorus and potassium, so that the curculigo orchioides Mao Zupei seedlings can be promoted to expand and gradually form fleshy roots within 2 months, and compared with the control of being sprayed by only assisting the same chemical fertilizer but not adopting the nutrient solution disclosed by the invention, the fleshy roots are promoted to be fast for 2-3 months.

Table 1 statistics of different examples and comparative examples
Survival rate of 60d | Rate of expansion of 60d fleshy root | Expansion rate of 120 d-old fleshy root | Expansion rate of 180 d-year-old fleshy root | 180 d-old seedling height | |
Example 1 | 97.4% | 34.6% | 99.7% | 100% | 31.6cm |
Example 2 | 96.9% | 52.7% | 100% | 100% | 32.8cm |
Example 3 | 97.3% | 46.8% | 100% | 100% | 29.1cm |
Comparative example 1 | 37.8% | 10.3% | 56.4% | 90.2% | 24.7cm |
Comparative example 2 | 61.9% | 0 | 21.7% | 84.6% | 16.3cm |
Comparative example 3 | 71.4% | 8.9% | 52.2% | 91.8% | 30.4cm |
