Technical Field
The invention relates to the technical field of agricultural planting, in particular to a method for interplanting radix pseudostellariae and melastoma dodecandrum lour trees.
Background
Pseudostellaria root, originally recorded in Bencao Shi Xin, is the dry root tuber of the perennial herb of Caryophyllaceae, Pseudostellaria heterophylla. From the perspective of traditional Chinese medicine, radix pseudostellariae is sweet in taste, slightly bitter, neutral in nature, and capable of entering spleen and lung channels, has the effect similar to ginseng, but weak in strength, is a clear and tonifying product in qi tonics, and can tonify lung, strengthen spleen and stomach, and treat lung deficiency cough, spleen deficiency anorexia, palpitation and spontaneous perspiration, mental fatigue, dry mouth, diarrhea, body deficiency and other symptoms. In recent years, the development of radix pseudostellariae functional health care products is continuously developed, the market demand of raw medicinal materials is increased year by year, the price of the medicinal materials is also increased, so that wild resources are dug too much and gradually reduced, the cultivation of the radix pseudostellariae is mainly based on cultivation, and at present, the cultivation of the radix pseudostellariae mainly focuses on cultivating virus-free seedlings, solving the problem of continuous cropping obstacles and solving the problem of plant diseases and insect pests.
The intercropping is a planting mode of planting the crops in the later growth period of the previous season crops or transplanting the crops in the later growth period of the previous season crops, and compared with a single crop planting mode, the intercropping mode not only can fully utilize the space in a staged mode, but also can comprehensively and reasonably utilize the nutrients and water in each layer of soil, improve the total annual output, change the microclimate in the field, achieve the mutual benefits and mutual benefits of the interplanted crops, and is a planting mode which can intensively utilize the time and the space. Radix pseudostellariae prefers mild and moist, is afraid of high temperature in summer, and shades the yin, so that the growth period is prolonged, and the yield is increased. The radix pseudostellariae is mainly produced by single seeds, can be harvested in most areas in 7-8 months, and can be sowed again in 11-12 months, so that the interval period is long, and the utilization rate of agricultural resources is low. Interplanting is often practiced in the production of radix pseudostellariae, but related researches are few so far, at present, the research of radix pseudostellariae interplanting mainly focuses on interplanting with vegetables, beans, Chinese herbal medicines such as cassia tora, radix bupleuri, coffee senna and the like and interplanting under a camellia oleifera abel tree, and as an invention patent with the application number of 201710495479.4, a planting method of camellia oleifera abel interplanting radix pseudostellariae is disclosed, and the planting method comprises forest land selection, planting soil arrangement, radix pseudostellariae cultivation bed setting, fertilization management and pest control, provides a unique organic fertilizer, can guarantee the growth of camellia oleifera abel and radix pseudostellariae simultaneously, and improves economic benefits; the invention patent with the application number of 201611267391.9 discloses a method for interplanting radix pseudostellariae under an oil tea tree forest, wherein the interplanting process comprises selection of the oil tea tree forest, arrangement of the oil tea tree forest, fertilization of an interplanting forest land, arrangement of a primary culture and interplanting forest land, ridging of the forest land, digging of planting holes, transplanting, management and harvesting, so that the utilization effect of forest soil resources can be improved, and the maintenance cost of a newly-built oil tea tree forest can be reduced; however, the current research on the interplanting of the radix pseudostellariae mainly aims to simply improve the utilization rate of soil and promote the economic benefit of crop harvest from one to two, and rarely changes the microclimate in the interplanting field, promotes the reciprocal benefit of the interplanted crops, solves the problems existing in the single cropping of the intercropped crops, establishes the micro-ecological environment commonly adapted to the interplanted plants and realizes the effect of 1+1 being more than 2.
