1. Qinglin stay protected bamboo shoots. During the period from April to June, it is the harvesting stage of bamboo shoots. When harvesting fresh bamboo shoots, don't forget to choose to keep the bamboo shoots, and leave the first batch of large-diameter healthy and robust bamboo shoots not to be taken. Generally, one-half-meter square is selected as the remaining one. Mother bamboo shoots. After the tail batch of forest bamboo shoots is susceptible to pests and diseases, the growth of the bamboo shoots ceases soon after they are exhumed. Therefore, after the tender bamboo shoots are harvested, a clear forest is to be cleared, dried bamboo shoots and broken bamboo shoots are removed, and rotten bamboo shoots with young pests are removed. , and then piled together and burned. Protect the bamboo shoots that are safe and keep the bamboo shoots safe on the forest. Eliminate harmful insects such as the nine insect pests, bamboo shoot borers, and bamboo shoot moths that harm female bamboo shoots at any time. 2. Yulin in addition to miscellaneous old bamboo. Summer and autumn are the growth and development of new mother bamboo and underground bamboo whip. In order to reduce the consumption of nutrients and promote the new whip prosperous growth, some aging bamboos, diseased bamboos, and trails should be promptly chopped to make new mother bamboos and strong mothers. Bamboo bamboo density is maintained at 3- to 5-pieces per square meter. 3. The loose soil excavated the old whip. After bamboo cutting, the dry bamboo shoots and old bamboo whips are increased year after year, resulting in the bamboo shoots and old hoe whipping in the locked woodland, forming soil compaction, impaired water and fertilizer supply, and severely affecting new whip proliferation and sprouting of bamboo shoots, which will lead to the next year. The shooting rate dropped significantly. Therefore, it is necessary to strengthen the winter loose soil, dig out the dry bamboo raft, remove the aging bamboo whip and weeds, shrubs. When loosening the soil and digging the old hoe, be careful not to damage the parent bamboo and the robust bamboo whip and the new bamboo sprouts. 4. Fertilizer cover cover weeds. Fertilizer is sufficient in winter, and more shoots are produced in the spring. After the soil is loosened, the base fertilizer is applied, and the livestock and poultry manure is mixed with appropriate amounts of phosphate fertilizer and potash fertilizer. The ditch application or pit application can be used. The amount of fertilizer is 0.5 kg per mother bamboo and the fine soil is placed after the application. Then, a layer of weeds or straw is laid on the bamboo forest floor with a thickness of 5 to 10 cm. Covering the grass is conducive to water conservation, fertilizer conservation, loosening the soil, enhancing soil fertility, promoting the growth of bamboo shoots, and increasing the yield of bamboo shoots.
