Five steps of white sow autumn
In recent years, in addition to medicinal purposes, Angelica also widely uses spices and food processing industries, and its demand has gradually increased. Therefore, the prospects for artificially grown whitefish are promising. White peony can be cultivated in all parts of the country from north to south. Generally, about 400 kilograms of dry goods can be produced per acre, and 500 kilograms can be produced at high yields. The benefit is over 3,500 yuan. Now we introduce its standardized cultivation techniques as follows: Selecting and preparing land for white peony prefers a warm, moist and sunny environment. It is better to choose a sandy soil with high topography, deep soil, loose fertility, and good drainage. Combining the site preparation, 2000 kg of compost (or 25 kg of compound fertilizer and 50 kg of phosphate fertilizer) per acre was added to the soil as a base fertilizer. Then, the land was leveled and made into a 1.3-meter-wide sorghum, surrounded by a deeper drainage ditch, and the sculpin was smashed into a turtle-back shape. The topsoil was loose and fine. Timely sowing of white pods is generally planted from early September to late October. It can be sown in the warm southern regions until early November, and should be planted before the frost falls in the cold northern regions. Seeding can be used sowing or drilling: (1) sowing. On the surface of the plant, 30-35 centimeters spacing and 20-25 centimeters of plant spacing were used to dig a hole, and the depth of the hole was 8-10 centimeters. The appropriate amount of grass ash and decomposed human urine were used as the base fertilizer, and the seed was sown. (2) Drilling. Open horizontal trenches on the surface of the trench. The trench spacing is 30-33 centimeters, the trench width is 10 centimeters, and the trench depth is 7-9 centimeters. The seeds are mixed with plant ash and uniformly sowed into the trench. Cover fine soil after sowing, not to see the seeds as degree. If the weather is dry, it should be properly watered after sowing and covered with grass moisturizing on the surface. Field management: Timely cultivating, weeding, and seedlings: When the seedling height is about 5 cm, we begin cultivating and weeding, and combine weeding for thinning. 5-7 seedlings were kept in each hole of hole sowing, and 1 seedling was kept every 3-5 cm. The seedling height is about 10 centimeters for the second time, seedlings leave 4-5 seedlings per hole, and drill seedlings every 7-9 centimeters. When the seedlings should be selected to retain the petiole was a purple seedlings, where the seedling petiole is green or yellow-green, the leaves concentrated in the upper part of the growth of excessive seedlings will often flower in the future, resulting in hollow roots, should be removed. In the early spring of the following year, the seedlings will be planted in the second half of February. Three seedlings will be planted at each hole on the sowing seedlings, and two seedlings will be drilled at the planting distance of 10-15 cm. Applying fertilizers in a timely manner during the process of plant growth can increase the yield and quality of white leeches. However, fertilization should also be appropriate, excessive fertilization, excessive growth, easy to cause bolting and flowering, reduce production, insufficient fertilizer, poor growth, and low yields. Generally top dressing four times; first and second combination of seedlings, applying 1500 kilograms of thin human fecal urine water per mu; third time after setting seedlings, 2000 kg of human fecal urine water per mu, plus superphosphate 30 kilograms; for the fourth time before and after Ching Ming Festival, 2500 kilograms of human fecal urine water was applied per mu and 150 kg of plant ash was added. Timely drainage of water in the field will cause the occurrence of root rot; the soil is too dry and the main root grows slowly, affecting the yield. Therefore, in the rainy season, it is often necessary to clear the gutters and drain water in time for drought. The irrigation time should be selected in the evening. Removal of calyx: During the period from May to June, some of the plants grow too profusely, they will twitch and blossom, and they should be removed in time. Otherwise, if they bloom, they will be hollow or rot, reducing the yield and quality.
