The technology of thunder bamboo shoot planting?
The following is the relevant material situation.
Thunder bamboo shoots high-yield cultivation technology
1, varieties and planting: first of all, we need to choose a good seed. Thunder bamboo is a cultivated type of early bamboo. Early bamboo has a variety of cultivation types, such as broad-leaved thunder bamboo, green shell thunder bamboo, early garden bamboo, etc., farmers are called early garden bamboo. The authentic thunder bamboo is the fine-leafed 5-leafed oval-leafed thunder bamboo. After determining the good seed, we should choose a good mother bamboo. The mother bamboo is required to be 2 years old, 10-15cm in circumference, low leafy branching, and healthy and disease-free. The mother bamboo should be dug up and brought to 15cm with whip, 68-70cm with whip, well-protected screws, and more than 7.5kg with soil. The planting season is good in summer and fall. When planting, the bottom of the pit should be flat, the bamboo whip should be put flat, appropriate shallow planting, whip soil close connection. Do deep digging shallow planting, under the tight on the loose, planting bamboo depth generally to bamboo whip into the soil 21 ~ 23cm is appropriate, after planting should be layered solid, whip root and soil does not leave a gap. Then pour 5-8kg of light fecal water, and then cover the soil into a steamed bun shape, covered with loose soil. Tall female bamboo should be staked and fixed. The weather is sunny to frequent watering. A reasonable planting density of 45 to 55 plants per mu.
2, suitable soil: Lei bamboo woodland selection should be leeward and sunny, light, gentle slope, soil layer deep, fertile, loose, breathable, well-drained sandy soil is good. Requirements slightly acidic to neutral, suitable ph value between 5 to 7, ordinary red soil, yellow soil can be cultivated. Saline soil, dead clay, low-lying waterlogged, high water table and factory-polluted land and alpine wind and transportation inconvenient places should not be planted. The newly planted land must be fully reorganized, dug about 25-30cm deep, removing tree roots and stones. After planting, the soil should be loosened and weeded in a timely manner, and within 2 years, the land should be plowed instead of supporting and intercropped with crops. Bamboo plantations are loosened 2 times a year, usually combined with fertilization in June and November each time. deep turning in June, shallow cutting in November. Each time you turn the soil, each mu must be added to the raw mountain yellow soil 1 ~ 1.5t, bamboo garden soil requirements to sponge ground, three soil, can soil, fertilizer, water.
3, adequate fertilizer: adequate fertilizer is the basis of high yield bamboo shoots. According to the analysis of China Forestry University Bamboo Research Office, each production of 50kg fresh bamboo shoots need to consume soil nitrogen 250-300g, phosphorus 60-88g, potassium 120-150g. If the production of 1t fresh bamboo shoots bamboo garden, the minimum annual fertilizer is effective nitrogen 7.5kg, effective phosphorus 2.1kg, effective potassium 3.2kg. according to which the bamboo bamboo shoots on the ratio of nitrogen, phosphorus, potassium, the three elements of the ratio is 5:1:2. ∶According to our cultivation experience, mu of thunder bamboo shoots 2.5 ~ 3.1t of fertilizer and fertilization methods are:
(1) long whip fertilizer: in June after the new bamboo forest, the application of urea 45kg, 110kg of phosphate fertilizer, potash 25kg, combined with the deep turning of the soil plus the birth of the yellow soil 1 ~ 1.5t, fertilizer turned into the soil, to promote the new growth of the whip fast growth, growth of the thick.
(2) germination fertilizer: September began to grow buds, Shi manure 1 ~ 1.2t, flush water more than double pouring.
(3) pregnant bamboo shoots fertilizer: early November pregnant bamboo shoots fertilizer, with cattle and pig pen fertilizer or chicken and duck manure 3 to 4t, turned into the soil, plus raw yellow soil 1 to 1.5t, to improve soil temperature, promote shoots grow up, long thick.
(4) long shoots of fertilizer: half a month before the shoots (about the end of December and early January) to apply long shoots of fertilizer (farmers say catalytic fertilizer), with urea 10 ~ 15kg; in addition, after digging shoots, but also apply hole fertilizer, each shoot hole with 3 ~ 5g urea.
4, adequate water: thunder bamboo like soil moist, but afraid of water. Flat bamboo forests, mountain bay windbreaks, sticky soil bamboo forests, to open a good drainage ditch, watering irrigation in the dry season. Thunder bamboo in the bamboo whip period most in need of water, at this time in May to June of the plum season, rainfall is relatively abundant, but the empty plum, high temperature and drought, will affect the growth of the bamboo whip, watering and irrigation. Secondly, in the period of pregnant shoots, the water content of thunder shoots is more than 85%, no water can't become bamboo shoots, so when you encounter autumn drought, long sunny and no rain, you have to water in time to promote the differentiation of shoots and shoots, and grow up. In addition, if you use mulch to early shoot bamboo garden, before covering the forest floor should be watered to promote the mulch fermentation, improve the effect of warming. The mulch is better with grain husk.
