Bamboo shoots can be used to cover bamboo shoots. Bamboo shoots can be listed more than 1 month in advance. Bamboo shoots are sold at a higher price, and better economic returns can be achieved. The production technology is introduced as follows:
First, covering the choice of bamboo forest
The bamboo forests used to cover shoots are generally grown in intensive bamboo forests under intensive management. After more than two years of ditch fertilization, the underground bamboo whip is rich and well-established; the bamboo age is young, and the first, second and third degree bamboos each account for about 30%: the soil layer is deep and the terrain is gentle: there is an irrigation facility or gravity flow. Easy irrigation.
Second, covering the management of bamboo forest
1. Standing bamboo management: Normally fertilized bamboo forests are generally represented by bamboo forests in flowering years. The phenomena of size and year are not obvious. Every year bamboo shoots are kept and old bamboo is cut. The density of mother bamboos was maintained between 150 and 180. That is, the density of 667 square meters (1 mu) of 30 bamboo shoots was maintained at about 180 strains. In the winter, the density of 667 square meters after cutting 7-year old bamboo was about 150. Mother bamboo updated in time. It can ensure that the underground bamboo whip is always strong and is conducive to making whip and pregnant bamboo shoots.
2. Soil Fertility Management: The general method of compound fertilization is used to replace the traditional deep turning tending to save the savings. Specific methods: In the period from April to May after spring bamboo shoot production, the ditch is opened along the horizontal direction, with a ditch depth of 20 cm and a width of 20 cm. The compound fertilizer is applied to the ditch and covered with soil. The ditch is separated by 2 to 3 meters, and the fertilizing amount of 667 square meters is 50 to 75 kilograms. In the following year, do the same furrowing on the unfertilized strips left behind. After multiple rounds of circulation, the effect of full-scale deep-turning can be eliminated, and laborers who have deep-turned each year can be saved.
3. Moisture management: From August to September, it was a period of shoot differentiation. In case of continuous drought at this time, the low price of bamboo shoots in Changning County will affect the bamboo shoot production in the coming year. Therefore, if it enters into continuous drought for more than 15 days in August, it should be irrigated with a reservoir or from a source of water in a timely manner. It is advisable that the amount of irrigation water be more than 85% of the relative soil moisture content in the tillage layer (30 cm).
Third, cover technical points
1. Covering materials: Covering materials include manure, bamboo leaves (straw, wheat hulls, weeds), and chaff.
2. Coverage time: According to the market price and demand, the coverage time is usually selected in mid-late and late November.
3. Coverage method: The cover will block rainwater seepage, so cover the time to choose the best day after the rain, otherwise it should be irrigated first. 667 square meters of 50 kg of compound fertilizer is firstly removed, and then 15 cm thick straw or bamboo leaves are used as ferments, and the straw or bamboo leaves are sprayed. To make its moisture content about 60%, to squeeze out straw or bamboo leaves by hand without water but the watermark is a cone on the hand, and finally cover the fresh bar fertilizer on the straw or bamboo leaves by 3 to 5 cm thick to accelerate the bamboo leaves or The straw was rotted and covered with a 20 cm thick chaff for insulation of the fermentation layer.
4. Bamboo shoot harvest: Bamboo leaves or rice straw under the effect of fertilizer will increase the temperature, so that the cover temperature above 17 °C, can promote the development of bamboo shoots in advance to expand, after 45 to 60 days can be gradually dug bamboo shoots. When the upper husk is cracked or pushed up, remove the cover in time, dig out the bamboo shoots, and then cover the soil back to the original place, cover the cover, and continue to heat and heat.
5. Cover removal: In early March, the temperature gradually increased, and the cover should be promptly removed to reduce the temperature of the covered soil, delay the unearthing of bamboo shoots, and facilitate the retention of mother bamboo. The upper husks of the cover can be collected and stored. When the cover is covered in the second half of the year, the rotted bamboo leaves or straw can be ploughed into the soil in combination with the woodland rake.
The top-mounted motor, the triangle tape, and the drive drive assembly make the inner cylinder run forward and reverse, and the washing effect is achieved through the mutual friction between the fabric and the fabric, and the fabric and the inner cylinder wall. The machine has built-in overheating, overload device, timing device, forward and reverse control device. The outer cylinder door is equipped with a safety device. If the door is opened during operation, the machine will stop running immediately to ensure the safety of the machine and the operator.
