Xiancao Datian Planting Technology
1. Site preparation: Site preparation involves coarse soil preparation and fine soil preparation. Roughly, the land of crop stubbles will be turned upside down to cover loose soil. The basal fertilizer shall be applied before the preparation of land, 500 kg of organic fertilizer per acre, 50 kg of phosphate fertilizer, 35 kg of compound fertilizer, and then deep plowing. The surface is finely ground and finely ground. That is to say, the ground is made into a box with a width of 150 to 180 cm, a height of 25 to 30 cm, and an appropriate length. Open deep drains around the field to prevent accumulation of water. After the ground is well covered, cover with black film.
2. Transplanting and planting: When planting, first use a wooden stick to make a hole through the covered black mulch or dig a hole on the mulch with a small hoe. The distance between the holes is 4050 cm. After the hole is played, the ready grass seedlings will be planted into the hole, and the soil will be used to return the hole. After the planting, the root water can be poured.
3, field management.
3.1 Water and fertilizer management. Grassgrass adapts to growth under high temperature and humid conditions, and should not be flooded for a long time. Soaking for more than two days will cause rot. It is necessary to keep the soil moist. In sunny days, it is necessary to infuse horses with water, and it is necessary to drain the rain in time to prevent the accumulation of water. When the grass seedlings grow to cover the ground, remove the black mulch. After removing the black mulch, fertilize the cultivator and trim the side ditch. Apply 15 kg of fertilizer per gram of potassium sulfate compound fertilizer. According to the condition of the seedlings, apply a compound fertilizer every 25 days or so, each time 15 kg per mu. Fertilizer to choose sunny, usually after 9 o'clock in the morning after 5 pm dew dry, while spreading with soft branches or broom to fertilize the grass from the grass blades to go to the ground. No rain should be given in a few days after fertilization.
3.2 disease, insects, grass management. Black mulch planting almost no weeding, saving time and labor. After 30 to 50 days after the immortalization of immortal plants, weeds can be sprayed with herbicides to prevent weeds from growing on weeds in the valley. Immature grass diseases and insect pests are few. Diseases mainly include physiological diseases caused by improper management of fertilizers and waters, such as potassium deficiency disease, and fertilizers are supplemented according to the situation. Pests are mainly lepidopteran pests such as Spodoptera litura. Pest control should use low toxicity and low residue pesticides.
4, timely harvest.
Harvested grass should be harvested before budding. Harvesting should be carried out on a sunny day. Harvesting should be done with a sickle to harvest the grass seedlings. Collect the fairy grass and make it into a small handle. Remove the roots, impurities and dirt, and let the grass be dried out in the ground. After drying in the field to 90% dryness, take it back home and then dry it. Do not drench it during the drying process. After the drying, the heads and tails were separated, and they were tied into small kilograms of about 20 kilograms.
5, storage and preservation.
After drying, Xiancao was stored in a dry, ventilated, dark place. The floor of the storage room should be raised. The grass should be covered with a film to prevent it from deteriorating.
