Mining method of bamboo shoots

The excavation and preservation of bamboo shoots is not only the harvest and utilization of forest by-products, but also a means to reclaim forest land and adjust the structure, density and quality of bamboo forests. The quality of digging bamboo shoots will directly affect the future growth and development of bamboo forests. Bamboo shoot digging and retaining technology is introduced as follows:

Bamboo shoots unearthed after "beginning of spring" are called bamboo shoots, and their emergence period can be divided into three stages: initial stage, from early February to early April; Mid-term, middle and late April; Later, in May and beyond. Bamboo shoots can be mined in the early and late stages, because the possibility of becoming bamboo is very small. Spring bamboo shoots unearthed in the middle period should be selected and preserved as bamboo because of their large size, strong health and strong vitality. What we want to dig are small-diameter bamboo shoots, weak bamboo shoots, shallow whip bamboo shoots, crooked bamboo shoots, small bamboo shoots, retreating bamboo shoots and so on. The characteristics of returning bamboo shoots are: there is no dew at the tip of bamboo shoots in sunny morning, the shell of bamboo shoots is depilated, the color is dark and the texture is soft. Don't hurt the whip, roots and buds when digging bamboo shoots. Cover the soil immediately after digging the bamboo shoots and fill them up.

Keep bamboo shoots and raise bamboo.

In the middle and late April, bamboo shoots with large and robust individuals, no pests and diseases, no damage and even distribution are selected to cultivate new bamboo. The number of bamboo shoots is 40-70 plants/mu per year, that is, the row spacing of bamboo shoots is 3. 1-4. 1 m. Off-year 10-20 plants/mu, that is, the spacing between plants with bamboo shoots is 5.8-8.2 meters. The flowering period is one year, with 30-50 bamboo shoots per mu and the row spacing of bamboo shoots is 3.7-4.7 meters. No matter what kind of bamboo mountain, the row spacing of bamboo shoots should be evenly distributed. Except for the reserved part, the rest can be fully excavated and utilized. Digged bamboo shoots should be peeled and cooked on the same day, soaked in running water, dried or dried in the sun, and cannot stay overnight, otherwise the bamboo shoots will age and deteriorate. In order to better protect bamboo shoots and raise bamboo, it is necessary to close hills and raise bamboo for 1-2 months before and after Tomb-Sweeping Day, and it is forbidden for people and animals to harm bamboo shoots and young bamboo.
