The Main Points of Sowing and Seedling Cultivation of Bamboo
Phyllostachys pubescens Seedling Seedling Techniques Phyllostachys pubescens, also known as bamboo, is a fast growing, high yield, good material, adaptable, and widely used. Bamboo is not only a superior raw material for construction and paper industry, but also a rare raw material for the manufacture of various tools, farm implements, stationery, furniture, musical instruments, and arts and crafts. One-to two-year-old seedlings of Moso bamboo were cultivated with seeds, which had more root whip and stronger ability to deliver. One seedling of bamboo seedlings could be divided into 3-5 cultivars within one year. After 5-6 years of bamboo afforestation, the forest can be matured, used year after year, and once afforestation can benefit for a long time. Moso bamboo afforestation is a shortcut to adjust the industrial structure, afforest green mountains, and develop the economy of mountainous areas. With the arrival of the large-scale development of the western region, the relevant provinces will implement the project of returning farmland to forests. Within a few years, the bamboo seedlings will be in short supply. Establishing a bamboo nursery and cultivating bamboo seedlings will bring considerable economic benefits to nursery families. The technical points for sowing bamboo seedlings are introduced as follows: Nursery choices: seedlings can be raised in mountainous areas or on hilly plains, requiring loose soil, fertile soil, convenient irrigation and drainage, preferably sandy loam or loam soil, bogey-soiled soil or poorly-drained depressions. Water pond. Fine soil preparation, sufficient base fertilizer: the new nursery for mountain nursery should be sowed 2-3 months before sowing, cutting down the miscellaneous irrigation, drying and burning, deep digging soil, picking the roots of the tree to remove grass roots. After about a month of weathering, dig and dig the earth 1-2 times before sowing, and then crush the soil as a bed. According to the soil texture and fertility, basal fertilizer should be applied. Potassium fertilizer, compost, human manure, and fire-fed soil should be used as far as possible. Superphosphate, calcium magnesium phosphate, and other fertilizers should be mixed and piled together after being mixed with earth fertilizer and compost. Each acre can be fired earth or soil fertilizer 5000-10000 kilograms, superphosphate 250-500 kilograms. Seeding season: In warm southern regions such as Guangxi, Guizhou, and southern Sichuan, field seedlings should be mainly planted in the fall. That is, when the bamboo seed matures, the seed germination rate increases with the planting, and all seedlings have already developed before the frost. After entering the winter, as long as appropriate measures are taken to prevent the cold, you can safely winter, the second spring seedlings began to give birth, high yield of bamboo seedlings. In northern regions, it is advisable to plant seedlings in spring or in nursery. Spring sowing should be early and should not exceed March. Late spring sowing, the germination rate is low, and because of the short growing period, there are fewer tillers. According to the test of the Jiangjiang horticulture farm in Xing'an County, bamboo was sowed in early spring and covered with plastic film. The sprouts emerged early and neatly, and bamboo shoots increased by 25%-30%. Sowing method: 1, dip teeth. Aim at the seeds commonly used insecticide powder seed preservation, to prevent insects feeding. Before sowing, wash the dressing powder with water and then soak it with 0.3% potassium permanganate for 6-12 hours to sow. If germination is used, the bamboo seeds can germinate quickly and neatly. Increase the germination rate of field farms, early emergence and delivery. The method is: Wash the powdered seeds and use wet sand dressing. Frequently sprinkling and spraying, until the seeds begin to dew, sieve out the sand and sow. Seed sowing with germinated seeds. Always spray water after sowing, to prevent "return bud" rotten species. 2, sowing. Drilling or holecasting are generally used. There are few seed sowing seeds, bamboo seedlings are distributed evenly, the growth is neat, and management is also convenient. Plant spacing is generally 30 cm. The 8-10 seeds are sowed on a uniform basis for each hole, and about 1.5 cm is covered with a fire of fine soil. Then cover a layer of straw and soak it. When drilled, the spacing of the ditch is about 30 cm, and the ditch should be perpendicular to the seedbed. Because Moso bamboo seeds are rich in starch, both birds and mice love to feed; Seedling management: After sowing, we must pay attention to keep the soil in the nursery soil moist and well ventilated, in order to facilitate the absorption of seeds, promote the transformation of enzymes, so that the bamboo seeds germinate quickly and neatly. At a temperature of 20-25°C, 15-20 days after sowing, germination was gradually unearthed. After the bamboo seedlings were unearthed, they should be removed in appropriate amounts in batches. Most of the sowing points were uncovered when they saw the seedlings, and they were uncovered after a week or so. If spring seedlings are to be planted in the spring, shady areas on sunny slopes should be shaded, shady sheds or shaded sticks can be used. The sticking sticks can be drawn on the spot. The method is simple and easy. The practice is to bundle 30 to 40 centimeters of T. edulis 3-5 into a bundle and insert it between rows of bamboo seedlings at a distance of 15 to 20 centimeters to obtain a good shade effect. After the bamboo shoots grow in the fall, they can be removed. To raise seedlings in the mountainous area, if you choose to sit on the half-sunny slope in the west to the east, you do not need shade. In order to make the bamboo seedlings evenly distributed, grow robustly, and increase the amount of seedlings and shoots, the dense bamboo seedlings can be taken out of the soil on cloudy rainy days, and transplanted in the hole of seedlings, with 1-2 plants per hole. Frequent weeding and ripping, timely irrigation with appropriate amounts of water; according to the fertility of the nursery and the characteristics of bamboo seedlings for growth and tillering, timely topdressing, etc., regular nursing of bamboo seedlings can be used to create the most suitable for the healthy growth of bamboo seedlings. The environment makes bamboo seedlings not only have high yields, but also have good specifications and quality. Moso bamboo seedlings are cultivated for one year until the end of fall and winter. The number of seedlings per hole will reach about 3-5 strains, and the height will be between 30-40cm to form bamboo groves. The seed production per acre is about 5000-6000 bushes and 2-3 thousand. In winter cold regions, simple cold measures should be taken to ensure safe wintering of Moso bamboo seedlings. The method is: to set up a wind barrier around the nursery, cover 5-10cm of soil around the bamboo grove, and sprinkle a layer of straw on the bamboo seedlings.
