Thunder bamboo is a good bamboo species in our country, which has the characteristics of early, high yield, long duration, taste, yearning, efficiency, adaptability, and high nutritional and commodity values。
1. Selection of lands and landscapes
1. 1 the site shall be set up on the basis of a choice of transport facilities, with slopes of less than 5 millimeters, deep soils, perturbable, wet, micro-acid or neutral sandy-fronted hills, plains, alluvial ripples and empty areas in front of houses。
1. 2 the gardening is generally carried out in the form of total land reclamation, prior to afforestation, the removal of vegetation weeds, shrubs, stakes, stones, etc., the reclamation of the land at a depth of about 30 cm, and the digging of holes as planned. Digging specifications: 60 cm x60 cm x50 cm, 80 cm x50 cm x40 cm. If necessary, each den is filled with 0. 5 kg of dead cake, or 15 to 25 kg of fertilizing, fertilizing and mixing。
2. Varieties and selection of female bamboo
2. 1 the variety of species is selected with broad leaves and fine leaves, which are 10-15 d earlier than wide leaves, sweet mouths, high yields and more economically efficient than wide leaves and are grown more frequently in production。
2. 2 the female chooses to be 2-3 cm in diameter, 1-2 years old, with a small branch, a strong leaf, disease-free and strong thunder bamboo. Excavating the bamboo, leaving it with 20 cm whipping, 30 cm whipping, careful protection of the lashes and the roots, with the mason belt not less than 25 - 30 cm in diameter, after the mackerel has been dug up, leaving 5 or 8 ctubs, cutting the bamboo, and cutting it evenly。
3. Afforestation of thunder bamboo
3. 1 during afforestation time, thunder bamboo can be planted four seasons a year, with autumn and winter, 9 november, and early spring, february being the best season。
3. 2 forest density is generally 750-1200 units per hectare。
3. 3 there are three main points to be understood in the planting method: first, the timely planting of the bamboo to be delivered to the site; and, second, the proper preplanting of the caves and mats. The female bamboo is then placed in the cave, and the whips are naturally spread, and attention is paid to the closeness of the lower part of the bamboo and the mats, so that the depth of the female bamboo is 31,5 cm deeper than the depth of the ground, then from the bottom up, layered back into the ground, so that the whips are closely connected with the earth; the third is to plant in the clear sky, so as to water the water, and to produce a thin pine field, or to replant a layer of straw in a fixed place, in order to increase the rate of afforestation。
Management of gardens
4. 1 timely replanting of dead bamboo during the year of afforestation。
4. 2 weeding of the pine soil contributes to the growth of bamboo by eliminating the competition of weeds for water fattening and improving soil performance. Weeding pine soil is done every three times, in combination with fertilisation, and close to shallow and deep. In general, the 1st session, in may-june, weeds were thrown 25 cm deep, the old bamboo whips were dug, and care was taken to protect the new bamboo whips and whips; the second cut the grass 15 cm deep in october and the third cut the grass in march。
4. 3 scientific fertilisation, based on the four long-lived characteristics of the thunderboot anniversary, which are long whipping periods, sprouts, gestation periods and long maturities, is applied to promote bamboo growth. Fertilizers are generally applied four times a year, and fertilization increases appropriately each year as the amount of bamboo is increased. The first, in january and march, was fertilized, resulting in long and long periods of fat. Combination fertilizer 150 kg per hectare, or 510 kg per set of bamboo in urine, is applied by the use of denization before the mackerel closes. When constricted, fertilizer is applied in ditches, with a distance of 0. 5 m and 10 cm deep, with a back-sliding soil, with human urine pouring 24 times the water and fertilization; (b) 2nd june, with long whipping, with multiple whipping and graft, with a compound fertilizer of 225 kg per hectare or 510 kg per set of bamboo, the same method as the first; in september, 3rd, fertilizing, sprung, sprung, fertilized and applied in the same manner as 2nd; the last one, in november-december, was fertilized, with 3000 kg per hectare of pasta or 15000-30,000 kg of farm fat。
4. 4 temperature insulation is generally used for grass, straw, grain shells, etc. (or an additional layer of agricultural film on the cover) every year between the end of november and december after the delivery of the bamboo forest, covering 10 to 30 cm thick gardens and controlling the surface temperature of the bamboo forest at about 15 to 17 °c (more than 20 °c) by thermometers, in time for the release of the cover. In fact, it is not easy, even burning, and it is 20 to 45 d earlier。
4. 5 the density and structure of the bamboo forest is maintained by rationally regulating the density and structure of the bamboo forest, maintaining the appropriate space within the forest, improving the ventilation and light conditions of the bamboo forest, maintaining the capacity to keep it alive and flourishing, and providing the basic conditions for its production. (a) new gardens, where one or two insect-free plants were kept in each of the same year, and where they were built to grow new bamboo; since the fifth year of the forest, there have been 9,000,12,000 robust bamboos per hectare, with a view to even distribution. (b) the percentage of children of the age of bamboo: around 30 per cent should be born in 3 years, and about 60 per cent and 70 per cent should be born in 1 or 2 years; in 4 years, bamboo is usually not kept and in more than 5 years it is cut off。
4. 6 the new bamboo cut-off, in which the new bamboo remaining in the year is growing young, should be cut off by 1/4 1/3 and 12115 in january, thus promoting new bamboo and wood saturation and enhancing and enhancing its defence against the frost and snow pressure of the harsh winter and cold spring。
5. The main pests of thunder bamboo are aphids, shellworms, bamboo locusts and coal pollution。
Prevention methods: (1) aphids, 40-50 per cent emulsion, 0. 05 per cent and 0. 1 per cent of solution or 0. 2 per cent of net mass for the eradication of americium. (2) shellworms: 1 1 2 m1 per plant with oxidizing ointment or methamidophos in water. (3) scrap locusts: timely spraying of larvae with a solution of 0. 125 per cent and 0. 167 per cent of 25 per cent of the insecticidal dichotomy; (4) coal pollution disease, which is treated early and at the same time for small aphids and shellworms, can mitigate the coal-contaminated disease caused by the two insects. If found, the disease should be trimmed, collected and burned from outside the bamboo forest。
