Description
Technical Field
The invention belongs to the technical field of crop cultivation, and particularly relates to a method for intercropping and reserving seeds in a field between Sichuan taro and leaf mustard.
Background
Mustard (Brassica juncea L.) is an important vegetable processing material. The cabbage mustard, the leaf tumor mustard, the tuber mustard and the leaf mustard in the leaf mustard are main raw materials of the Sichuan pickled Chinese cabbage, and are tender and crisp in texture, delicious in taste and deeply popular with consumers. Leaf mustard is mostly used for processing, the sowing time is in the middle of 9 months, and the harvesting time is in the middle of 2 months.
Colocasia esculenta (L.) Schott is a perennial herb of the genus Colocasiae of the family Araceae, named taro, etc. Dasheen is native to the east of India and Malaysia. The cultivation history of China is long, and the vegetable and staple food can be made. Especially vitamin C, and also contains a mucosaponin. Can be ground into powder, ground into pulp and mixed with rice flour to make taro powder, which is easy to digest after eating, and is especially suitable for patients with gastrointestinal diseases and tuberculosis, the elderly and children. The fructus Colocasiae Esculentae contains abundant fluorine, and has effects of inhibiting abnormal cell proliferation, cleaning teeth, and preventing dental caries. Taro is mainly subjected to asexual propagation, the taro planting quantity is large, the labor demand for storehouse storage is large, and the storage condition is not easy to control; the land occupation of the original field is large, which causes land waste, frost is easy to occur in winter, and the output value is reduced.
Disclosure of Invention
The invention aims to provide a method for intercropping original field seeds by using Tetrakistrodon steudnera tuber and leaf mustard, and solves the technical problems of land waste, frost liability and low yield caused by large land occupation of the original field seeds in the prior art.
The invention provides a method for interplanting raw field seeds of Szechwan taro and leaf mustard, which comprises the following steps:

s4, fertilizer and water management: applying enough base fertilizer, applying early-stage fertilizer frequently, applying middle-stage fertilizer again, and applying little or no later-stage fertilizer;
s5, intertillage ridging: during conventional cultivation, 1-time hilling is needed in sunstroke; ridging for the 2 nd time in heavy summer, and combining with secondary additional fertilization, wherein the ridging thickness is 15-20 cm, so that the yam tubers are not exposed out of the ground;
s6, taro turning: in the middle and late ten days of 9 months, when the stem leaves of the taro turn yellow, the stem leaves of the taro are cut off at the same time in the morning and at noon of fine days, and are horizontally placed between plants, aired, cleaned of weeds and insect pests in the field and the field, and the plants are disinfected by Kejia and planted in the field, and poured into the taro field for standby;
s7, leaf mustard seedling culture: in the middle late 9 months, selecting excellent leaf mustard varieties to grow seedlings in field conventionally;
s8, transplanting the leaf mustard: transplanting the leaf mustard into a grain dumping taro field;
s9, harvesting and cleaning a field: and (4) harvesting when the mature mustard plants reach the maturity of the commodity vegetables but are not bolting, wherein the harvesting time is generally in the middle and last ten days of 2 months. Cleaning the field and garden in time after harvesting, cleaning the diseased residual leaves and weeds, and performing centralized harmless treatment;
s10, seed reproduction of taros in the second year: loosening soil around the seed of taro, watering, and germinating in late and middle 3 months.
The working principle is as follows: by adopting an intercropping mode of taro and leaf mustard, the vacant autumn and winter after taro is poured can be effectively utilized to plant leaf mustard, and the income is increased; the root system of the leaf mustard is distributed shallowly, the soil fertility is utilized hierarchically, the weight-losing effect is remarkable, meanwhile, the leaf mustard has developed nutrient body, and the leaf mustard can be used for preventing frost and weed for taro seeds in winter. The arrangement of the row spacing of the taro plants is favorable for the continuous seed reservation in the next year, and the interplanting of the leaf mustard is facilitated.
Further, selecting the taro variety and the taro seed in the step S1: selecting seed taro with disease resistance, high quality, high yield, good marketability, full terminal bud, stout corms, no plant diseases and insect pests and complete shape as seeds, wherein the weight of each seed taro is preferably 50g, and the seed taro is a good variety which accords with the consumption habits of target markets.
Further, the taro variety in step S1 is: chuankui No. 1.
Further, in the step S4, the top dressing is mainly nitrogen potassium fertilizer and is assisted by phosphate fertilizer, and 1 time of seedling raising fertilizer is top dressing when the 1 st leaf of the seedling is unfolded, wherein each 667m of the top dressing is2Adding 1000kg of thoroughly decomposed organic fertilizer, 4kg-6kg of urea and water into the thoroughly decomposed organic fertilizer; dressing the 2 nd time when 3-4 leaves are needed, every 667m21300kg-1700kg of decomposed organic fertilizer is added with 8kg-12kg of potassium sulfate and added with water, the soil is kept moist in the whole growth period of the taro, and watering is carried out in time when drought occurs.
Further, the mustard is Sichuan mustard No. 1 or Sichuan mustard No. 2.
Furthermore, in the step S8, the row spacing of the leaf mustard plants is 50cm multiplied by 50cm, the leaf mustard plants are arranged in double rows and are uniformly planted among the rows of the tuber mustard, and the root mustard plants are watered with the chemical root fixing water after being transplanted.
Further, managing the mustard rich water: the top dressing is carried out by taking quick-acting nitrogen fertilizer as a main material and adopting the principles of 'light application in the early stage, heavy application in the middle stage and seedling observation and fertilizer supplement in the later stage', and the top dressing is generally carried out for 2-3 times in the growth period, and each time is 666.7m225 kg-30 kg of urea is applied in total, and 30%, 60% and 10% of the total topdressing amount are applied respectively after the survival of the permanent planting, the opening stage and the rosette stage in combination with watering.
The invention has the beneficial effects that:
1. the method realizes the intercropping mode of taro and leaf mustard, realizes the purposes of comprehensive development and utilization of space-time resources and cost saving and efficiency improvement for farmers, and can solve the problems of waste of seed reserving land and easy frost in the original field of the Sichuan taro by using the leaf mustard intercropping mode.
