Description
Technical Field
The invention belongs to the field of agricultural cultivation, and particularly relates to a preparation for promoting yield increase of radix puerariae and application thereof.
Background
Pueraria thomsonii Benth is a perennial vine deciduous plant of the family Leguminosae, also called radix Puerariae and Pueraria lobata, and is used as a medicine from the root. The kudzu root is a traditional Chinese medicine commonly used in China, is a health food, is sweet in taste and cool in nature, and has the effects of promoting the production of body fluid to quench thirst, expelling muscles and allaying fever, clearing and activating the channels and collaterals, invigorating yang to arrest diarrhea, relieving alcoholism, promoting eruption and the like. The kudzu root is a traditional medicine-food dual-purpose plant in China, not only is a traditional Chinese medicinal material commonly used clinically, but also is a traditional food deeply popular with people, and various products prepared by taking the kudzu root as a main raw material are available in the market at present, such as: kudzu vine root beverage, kudzu vine root health-care bean jelly, kudzu vine root fine dried noodles, kudzu vine root soft sweets, kudzu vine milk, kudzu vine root health-care oral liquid and the like. The market demand of radix puerariae at home and abroad increases year by year. The development of the kudzuvine root has wide market prospect at home and abroad. The planted kudzu roots can play roles in preventing and treating water loss and soil erosion and maintaining water and soil, can increase the content of nitrogen and organic matters in soil and effectively improve soil components. The kudzu vine root is more and more valued by governments and farmers due to good economic and ecological benefits, and becomes a popular planting project at present.
In the kudzu planting process, in order to promote the growth of root tuber, the excessive growth of kudzu is inhibited, so that the side vines which germinate need to be cut off at any time to promote the growth of the main vines. In the planting process, the most main diseases are rust diseases which mainly damage leaves, and when the diseases are serious, leaf blister spots are densely distributed and are full of rust powder, even the leaves deform, so that the photosynthesis of plants is blocked, the water transpiration amount is greatly increased, and finally the leaves gradually dry, so that the expansion of underground root tubers is influenced, and the yield is reduced.
Aiming at the yield increase of the kudzuvine root, the method for planting the kudzuvine root is mainly explored from a planting method, for example, the application with the application number of 201510619758.8; the published document [1] the chuanju, the kudzu root planting technical specification [ J ] Henan agriculture, 2019(10), 47 [2] Qian Xiujin, the kudzu root cultivation technical point [ J ] the agricultural technology and equipment, 2017(04), 60-62+65.[3] Wendesheng, GaoAiqin, Huangzhi, Zhang Enyi, Yang jin, Luoyun, Liunengxian, the kudzu root standardized planting production operating specification [ J ] the modern traditional Chinese medicine research and practice, 2007(03), 10-14 ] are also reported from the planting angle. The three documents all disclose that pruning and vine-shaping are needed in the kudzu vine planting process, namely, in the kudzu vine growing process, attention needs to be paid to pruning and vine-shaping, excessive growth is inhibited, and root tuber expansion is promoted. The method comprises the following specific steps: firstly, 1-2 kudzu vine stems can be left for each kudzu seedling to be cultured to form a main vine, branch lateral vines are not left when the kudzu vines do not grow to 1m, the germinated lateral vines need to be cut off at any time, the main vine is promoted to grow thick and strong, the germinated lateral vines with the length of more than 1m are all left, vine leaf growth is promoted, and sufficient photosynthetic leaf area is kept; and secondly, when the distance between the growth point of all lateral tendrils and the root reaches 3m, removing terminal buds, inhibiting overgrowth of the kudzu, promoting the growth of thick and strong kudzu and axillary buds, and ensuring the supply of nutrient substances required by root tuber expansion.
However, the operation mode wastes time and labor, and the yield increasing effect of the coarse radix puerariae is not obvious, so that the invention aims to further promote the yield increase of the radix puerariae.
Maleic hydrazide, also known as cynarin, maleic hydrazide, 1, 2-dihydro-3, 6-pyridazinedione, anhydromalohydrazide, etc., is a selective herbicide or temporary plant growth inhibitor. The agent can enter plants through the cuticle of the leaf surface, reduce photosynthesis, osmotic pressure and transpiration, and strongly inhibit the growth of buds. The maleic hydrazide compound is mainly used for preventing sprouting of potato tubers, onions, garlic, radishes and the like during storage, has the effect of inhibiting the growth and the flowering of crops, but not all plants have the effect of inhibiting the sprouting of the kudzu, and no maleic hydrazide is reported at present for inhibiting sprouting of the kudzu.
Epoxiconazole, having the english name epoxyconazole and the chemical name: (2RS, 3SR) -3- (2-chlorophenyl) -2- (4-fluorophenyl) -2- [ (1H1, 2, 4-triazol-1-yl) methyl ] oxirane. Epoxiconazole is a systemic triazole fungicide, inhibits the synthesis of ergosterol of pathogenic bacteria, and inhibits the formation of cell walls of the pathogenic bacteria, and epoxiconazole molecules have strong affinity to a fungal enzyme (14-dencthylase) and can effectively inhibit pathogenic fungi. Epoxiconazole can improve the activity of the valbutinase of crops, cause the contraction of a fungal sucker, inhibit the invasion of pathogenic bacteria and have good control effect on diseases such as leaf spot, powdery mildew, rust disease, anthracnose, white rot and the like.
Sodium naphthaleneacetate: the plant growth regulator is a broad-spectrum plant growth regulator, can quickly promote cell division and expansion (fruit swelling agent and swelling agent), can induce to form adventitious roots (rooting agent), has the functions of regulating growth, promoting rooting, sprouting and flowering, preventing flower and fruit dropping, forming seedless fruits, promoting precocity, increasing yield and the like, and can also enhance the drought resistance, cold resistance, disease resistance, salt and alkali resistance and dry and hot wind resistance of plants. Is a plant growth regulator with broad spectrum, high efficiency and low toxicity.
At present, no report that the three components have synergistic effect after being mixed exists, and no report that the reagent is used for increasing the yield of the radix puerariae exists.
