Description

Regulation and control method for improving yield of mugwort in more than one year
Technical Field
The invention relates to the field of plant production, in particular to a method for regulating and controlling the yield of mugwort in one year.
Background
Chinese mugwort herbArtemisia argyiLevl et Van) is perennial herb or semi-shrub plant of Artemisia of Compositae, is rich in volatile oil and flavonoid, and has effects of warming channel, eliminating dampness, dispelling cold, stopping bleeding, inhibiting bacteria, resisting insect, and resisting oxidation. In addition to medicinal use, recent researches have found that mugwort leaf and Ai Gan have important application value in the fields of food, health care, cosmetics, livestock and the like. The wide application of the Chinese mugwort leaf tea enables the domestic mugwort leaf tea leaves to have the requirement of 4.5-5 ten thousand tons in 2017 and the requirement of more than 8 ten thousand tons in 2021. Although the mugwort industry has developed rapidly in the last 10 years, current scattered farmer planting occupies a relatively large weight. The standard planting regulations of the mugwort are not perfect, the production enthusiasm of farmers is seriously influenced by market quotation development, and certain hidden trouble is brought to the safe production of the mugwort. Therefore, the method for ensuring high and stable yield is significant for the development of the mugwort industry.
Ai Caoshi has strong stress, has no strict requirement on the growth environment, and is usually wild in the roadside wild land. In China, mugwort is spread over other provinces except extremely arid and alpine regions. Under the condition of artificial cultivation, harvesting can be performed about 2 months from the emergence of seedlings, namely about 3 stubbles are harvested each year before and after the noon festival, about 7 months in the middle and late ten days and before and after the national celebration festival. In regions with proper climate in the south, 1 stubble of rice can be harvested before winter. In the artificial cultivation, the rhizomes are mostly used as the starting materials, the cultivation is horizontally carried out before and after 11 months in the previous year, the germination and emergence of seedlings are carried out in 3 months in the next year, and the survival rate is high. However, after the previous crop is harvested, the moxa can emerge through residual stalk axillary buds, and can also grow from underground rhizomes to emerge, the emergence time is inconsistent, and the uniformity is poor. When the plants grow to about 1 month, the lower leaves start to dry and fall seriously, and leaves with the height of about 50 and cm from the ground at the lower part are left for 2 months, so that the harvest quantity of the leaves is seriously reduced. In order to avoid the lower leaf from falling, in actual cultivation production, harvesting is carried out when the height is 1.5 and m is even lower, and the yield and the content of active ingredients such as volatile oil at the moment do not reach the optimal level. This has become a bottleneck problem in mugwort production, and therefore, improving mugwort emergence uniformity, reducing lower leaf drop can help the efficient production of mugwort.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide a regulating and controlling method for improving the yield of mugwort in one year, which promotes the increase of leaves, improves the chlorophyll content, effectively eases the falling of the lower leaves, improves the leaf-stem ratio, increases the biomass and improves the harvest yield.
The technical scheme adopted by the invention is characterized in that: the root-shaped stems are used as starting materials, 1 seedling promoting liquid is respectively irrigated to the root-shaped stems before emergence of first seedlings in spring or the residual stems after subsequent harvesting of mugwort, and the seedling promoting liquid is 25-150 mug/L chlorine dioxide aqueous solution.
The Ai Caobao includes mugwort, wormwood.
Further, respectively spraying growth promoting liquid to the leaves at the time of 2 weeks and 6 weeks of seedling emergence, wherein each spraying is carried out continuously for 2 days; the growth promoting liquid is an aqueous solution of 1-50 mug/L chlorine dioxide and 0.3 per mill sodium alkyl benzene sulfonate.
According to the invention, the seedling emergence of the mugwort rhizome is promoted by irrigating with the chlorine dioxide solution with specific concentration, the growth and elongation of the rhizome are promoted, the seedling emergence time is shortened, and the seedling emergence quality is improved; and spraying a mixed solution of chlorine dioxide and sodium alkyl benzene sulfonate in seedling stage and adult stage to regulate plant growth, promote plant growth, increase leaf area, increase chlorophyll content, increase biomass, remarkably reduce leaf withering condition at lower part, and increase leaf harvest yield. The used reagent has extremely low working concentration, low price and no environmental safety risk, and can effectively solve the problems that seedlings are not uniform after the previous crop is harvested and the lower blade is withered and falls to reduce the harvest yield in the current production of the mugwort. The research of chlorine dioxide in postharvest fresh-keeping is more, and the research shows that the concentration of the chlorine dioxide of more than 10 mg/L can kill surface microorganisms, and the aging is delayed by inhibiting the ethylene synthesis of postharvest fruits and vegetables, so that the shelf life is prolonged. However, chlorine dioxide with a concentration which is hundreds of times lower than that of disinfection has little influence on living plant growth, and only the former report of the subject group is that adding chlorine dioxide into a culture medium can enable chrysanthemum to grow into seedlings in one step (CN 112586358A), which suggests that the chrysanthemum can be used as a signal molecule to regulate and control the metabolism of plant endogenous hormones so as to participate in regulating and controlling plant growth.

Detailed Description
Example one irrigation seedling promoting liquid improves first crop emergence efficiency
According to chemical reaction 5naclo+4hcl=4clo 2 +5NaCl+2H 2 And O, the rapid preparation of chlorine dioxide is realized by adopting the reaction of sodium chlorite and hydrochloric acid. Weighing 0.15 g sodium chlorite, adding 5 mL distilled water into a brown bottle, adding 0.5 mL food-grade hydrochloric acid after the sodium chlorite is completely dissolved, reacting for 10 min, adding 495 mL distilled water, and uniformly mixing to obtain 100 mg/L chlorine dioxide water solution. The concentration required before the application is needed.
In the previous year 11 months, the underground roots of the wormwood are dug, tender rhizomes are picked out, the rhizomes are cut into 4-5 cm long sections, furrows are reserved in 40-45 cm, the rhizomes are placed in the furrows in a flat mode according to 15 cm plant spacing, and then soil is covered and compacted.
And in the following 3 months 1 day to 10 days, fully irrigating the planted rhizomes for 1 time with 30 mug/L of chlorine dioxide water solution, and using the irrigated water as a control. After 4 days of watering, as shown in FIG. 1, the treated group had a large number of new rootstocks (indicated by arrows) grown, and the growth was significantly better than that of the control group. After 10 days of watering, as shown in fig. 2, the treated group had a large number of new seedlings (indicated by arrows) and the emergence was significantly better than that of the control group.
Second embodiment of irrigating seedling promoting liquid to improve residual stalk re-emergence efficiency after harvesting mugwort
After the previous crop of mugwort is harvested, the residual stalks are fully irrigated again for 1 time with 40 mug/L of chlorine dioxide water solution, and the water with the same amount is sprayed as a control. After 7 days of watering, as shown in FIG. 3, the treated group had a large number of new rhizomes (indicated by arrows) and the growth was significantly better than that of the control group. After 14 days of watering, as shown in fig. 4, the treated group had a large number of new seedlings (indicated by arrows) and the emergence was significantly better than that of the control.
Example three spraying growth promoting liquid to regulate and control growth of seedlings of mugwort
When the seedlings of the wormwood emerge for 2 weeks, an aqueous solution containing 25 mug/L of chlorine dioxide and 0.3 per mill of sodium alkylbenzenesulfonate is sprayed, and an equal amount of water is sprayed as a control. Spraying on all leaf surfaces is preferable, and spraying is carried out continuously for 2 days. After 7 days of spraying, as shown in fig. 5, the treated group Ai Miao was observed to grow rapidly, and the plant height was significantly higher than that of the control group.
Fourth example spraying growth-promoting liquid to control growth of mugwort leaves
In the third example, an aqueous solution containing 35. Mu.g/L chlorine dioxide and 0.3% sodium alkylbenzenesulfonate was sprayed for 6 weeks after emergence of the seedlings, and an equal amount of water was sprayed as a control. Spraying on all leaf surfaces is preferable, and spraying is carried out continuously for 2 days. 7 days after spraying, as shown in fig. 6, it can be observed that the yellow leaf of Ai Miaoxia parts of the treatment group is significantly lighter than that of the control group. After 14 days of spraying treatment, as shown in fig. 7, the lower leaves of the treatment group are obviously lighter in withered condition than the control group; as shown in FIG. 8, the chlorophyll content of the control group and the control group was 0.68 mg/g, and the chlorophyll content of the treated group and the control group was 1.06 mg/g, which is improved by 61% compared with the control group.
Fifth example spraying growth promoting liquid to increase mugwort yield
And (5) comprehensively applying the seedling promoting liquid and the growth promoting liquid, and measuring the output of the mugwort for 2 months after seedling emergence. As shown in fig. 9, the treatment group blade area increases significantly; as shown in FIG. 10, the control group had a total area of 5 to 9 leaves 133.87 cm 2 Total area 172.75 cm of 5-9 leaves in treatment group 2 The increase is 29%. As shown in fig. 11, the individual dry weight harvest yield was increased from 7.7. 7.7 g in the control group to 12.1. 12.1 g in the treatment group by 57%; as shown in fig. 12, the leaf/stem ratio (dry weight) was increased from 0.81 for the control group to 1.1 for the treatment group, which was a 36% improvement.
The results show that the chlorine dioxide with proper concentration can obviously promote the growth of rhizomes before emergence, improve the emergence rate and the emergence speed, effectively promote the growth of seedlings by spraying the chlorine dioxide and the sodium alkyl benzene sulfonate solution in the seedling stage, obviously increase the leaf area by spraying in the plant stage, reduce the dry and falling of bottom leaves and improve the yield.
The invention provides an agronomic control method for promoting the efficient production of the wormwood, which is simple and convenient to operate and low in cost, and can promote the development of the wormwood artificial cultivation industry.
