But the technical scheme is suitable for the high-temperature and high-humidity areas of Sichuan, can not solve the technical problems of wide application of the red cedrela sinensis in the open field in mountain areas, and meanwhile, the prior art needs to adopt a facility technology, and has longer cultivation period and high cost. Therefore, a red Chinese toon cultivation management method for realizing continuous multi-stubble harvesting of fresh high-quality Chinese toon buds, prolonging the supply period and solving the blank period is urgently needed.
Disclosure of Invention
The invention aims to provide a method for picking multiple stubbles of red Chinese toon sprouts in open field in mountain areas, which selects strong Chinese toon tree in a Chinese toon garden, and utilizes natural conditions of cool autumn climate in mountain areas, abundant precipitation in 8-9 months in rainy season and 15-DEG temperature difference between day and night to artificially break dormancy of the Chinese toon tree by means of stumping, threshing and the like, promote tree bodies to update sprouting and bud, realize bright brown red, aromatic and excellent-quality fresh red Chinese toon sprouts which naturally grow in open field autumn in multiple stubbles in mountain areas, and solve the problems of long cultivation period and high cost in the prior art.
Therefore, the invention provides a method for picking multiple stubbles of red Chinese toon autumn buds in open field in mountain areas, which selects and plants the robust Chinese toon tree in a Chinese toon garden for two years or more, and comprises the following steps:
s1, stumping: harvesting first and second stubbles of red Chinese toon buds in spring, stumping and cutting the Chinese toon tree, and promoting germination of new seedlings;
S2, bud retention: selecting and reserving strong buds in good time before and after mid-July, and erasing young weak buds;
S3, intertillage: timely carrying out intertillage, scraping, hoeing and loosening the soil after rain, breaking the soil hardening and removing weeds in the garden;
S4, additional fertilizer: soil moisture is used for topdressing according to the growth vigor of the Chinese toon tree in June and June to June;
S5, dwarfing: at the bottom of six months to the beginning of July, dwarfing the toona sinensis tree with vigorous growth tendency;
s6, pest control: in the last ten days of June to August, the red cedrela sinensis can possibly generate rust disease and insect damage of the cicada, and if the damage happens, the damage should be prevented and treated in time;
s7, defoliating: selecting a cedrela sinensis tree with good lignification, formed terminal buds and new branches in mid-August, removing all the complex leaves of the trunk, and covering the complex leaves around a tree disk;
s8, sprout dressing fertilizer: 10 days after the step S7, when the buds of the Chinese toon sprout, applying Gao Jia ternary compound fertilizer 15-20 kg per mu;
S9, harvesting autumn buds: and 20-25 days after the step S7, picking the toona sinensis buds, wherein 3-4 stubbles can be picked before frost.
S10, autumn management: after autumn buds are harvested, spreading thoroughly decomposed farmyard manure in a garden as a base fertilizer, and turning the fertilizer into soil in combination with intertillage;
preferably, the planting method is suitable for open field planting of red cedrela sinensis areas.
Further preferably, the planting method is particularly suitable for planting the mountain areas with cool red cedrela sinensis climate.
Preferably, the Chinese toon garden is planted on a mountain sunny slope and a semi-sunny slope with loose and deep soil, good air permeability and high organic matter content, and the Chinese toon is red, strong in adaptability, strong in stress resistance, good in quality, brownish red, bright in color, thick, fat, tender, juicy, rich in fragrance, delicious in taste and rich in nutrition.
Further preferably, the planting method of the Chinese toon tree in the Chinese toon garden comprises the steps of selecting annual healthy and high-quality tree seedlings with high lignification degree, full top buds, strong and developed root systems and no plant diseases from 80-100 cm of the root tiller breeding height, 80-100 cm of the stem thickness at the 10cm position on the ground part, transplanting the tree seedlings with root lumps in soil moisture into planting holes, planting the tree seedlings in each hole according to the row spacing of 80-100 cm, the plant spacing of 35-40 cm and 1800-2000 plants per mu before sprouting of the tree seedlings in the early spring soil-thawed seedlings;
further preferably, the planting of the Chinese toon tree in the current year is that after field planting, stubble cutting and chopping are carried out at the position of 15-20 cm or 5-8 cm of the seedling leaving the ground, soil loosening and weeding are carried out in time after rain, new buds grow to 18-20 cm, 1-2 strong buds are reserved, NPK ternary compound fertilizer 15-20 kg is applied by soil moisture ditching or hole application for 6-7 months, 5-10 kg urea is additionally added to barren land, and foot base fertilizer is applied by combining intertillage after fallen leaves.
Preferably, in the step S1, after spring buds are harvested, stumping and chopping are immediately carried out at the position 15-20 cm of the trunk of the Chinese toon, so that the dwarfing of the tree seedlings is realized, the germination and bud strengthening are promoted, and the germination and full bud is inoculated.
Preferably, in the step S2, when the new-born young buds grow to 18-20 cm, 1-2 strong buds are selected and reserved, other weak buds are removed, and the strong single-stem tree is cultivated.
Preferably, in the step S3, the seedlings are cultivated, loosened and weeding is carried out for 2-3 times after the period of growing the seedlings is rained, and the weed is piled around the tree disk.
