The shed is covered with cultivating yellow stalks of yellow and yellow leaves, and the leaves are yellow, and the quality is tender and delicious. This cultivation method is carried out by combining the soil and the cover shed measures. The method is complicated and the materials used are also more.
1. The material used for the cultivation method of the straw cover is mainly straw.
For every 667 square meters (one acre), Huangtian prepares 2,500 kilograms of straw, and the bamboo shoots are 500 kilograms. A small amount of string is needed. The commonly used variety for the cultivation of sorghum is Maji.
2. The roots of the roots are cultured in a plot that grows vigorously, has no pests and diseases, and is not lacking in seedlings. After harvesting the last sapling, clean up the pastoral. When the plant grows to 40-50 cm, a person's urine with a concentration of 30% is chased. When the soil is slightly dry, the soil is cultivated.
3. The purpose of the soil is to soften the sheath of the leek and to prevent the plant from lodging. Since this cultivation method of yellowing can be carried out all year round, the soil can be carried out at any time. But the method varies depending on the season and temperature.
During the first soil cultivation, such as in the spring and autumn cool seasons, the height of the soil should be at the junction of the leaves and the sheath; for example, in the hot summer, the height of the soil should be about 3 cm below the junction of the leaves and sheaths; , 1-2 cm above the junction. When cultivating soil, try to keep the soil loose and ventilated to prevent excessive tightening and moisture, causing decay. After the first soiling, when the leaf sheath grows 3-6 cm, the second top dressing and soiling are carried out in the same way as the first time. If the plant grows better, a third soil can be used. After three times of soiling, when the whiteness grows to 15-20 cm, the grass cover is covered.
4. Before covering the grass shed with the straw shed, cut off the sapling leaves on the soil. The height of the cutting blade varies from season to season. The cutting in winter can be 1 cm below the junction of the blade and the sheath; the cutting in the spring and autumn is at the junction; the summer should be 1 cm above the junction. After cutting off the leaves, clean up the garden and build a grass shed. The grass shed is built on each line of leeks. First, level the surface of the straw shed, that is, 3-4 cm of soil layer on both sides of the raft formed by the soil to form a ladder to facilitate the placement of the shed.
The ledge of the grass shed is inserted into the step of the leek by the short bamboo poles of 65-70 cm long. Four inserts are inserted on each side of the 70 cm, and the upper end is tied with a female figure. Three bamboo poles are shared on the top and sides to form three beams and become double-roofed. The straw is caught in the double roof, which is a straw shed.
The construction of the straw shed should pay attention to the following matters: water should not be stored in the trench, and it should be drained in time after the rain to avoid the decay of the leek; the grass on the grass shed should be smooth, smooth, rainproof and opaque; the near-ground part, straw There is a certain gap with the ground to facilitate ventilation; the grass shed is blocked with grass at both ends to prevent sunlight from entering.
5. After harvesting the grass shed, the first knife can be harvested in 20 days in spring and autumn; about 12-14 days in summer; and harvested in winter for about 40 days. When harvesting, go to the grass shed, pick up the soil, and harvest from 0.5-1 cm on the bulb. After cutting, the glutinous rice noodles are cultivated in the open field to restore the growth potential. Do not wash with water after the harvest, so as not to rot. Can shake the net, pick up the yellow dry, broken leaves, tied into a small hand to the market. It can receive 12,000-22500 kg per hectare.
