How to grow white? White peony is a traditional Chinese medicine plant with good medicinal value. In recent years, the market has been quite good. The farmers who planted white peony have gradually increased. How do white carp grow high-yield? Today we are going to study the introduction of white carp planting points in the central and southern regions of Hebei Province.
First, the regional situation
The central and southern parts of Hebei Province are located in the hinterland of the North China Plain. The terrain is flat and east of the Taihang Mountains. The main terrain consists of the Taihang Mountains, the hilly areas in front of the Taihang Mountains and the vast North China Plain. The geographical position is superior and the land resources are abundant. Per capita water resources are less, water resources development and utilization rate is higher, and groundwater is in an over-exploited state. The total amount of water resources is relatively small, the quality of water environment is relatively poor, and local water pollution is more severe. The risk of natural disasters is low and the stability of ecosystems is strong.
Second, introduction and cultivation techniques
1. Soil preparation and fertilization
Choose deep, fertile and loose soil, well-drained sandy soil with humus and damp land, and grow on shady or damp land. The ploughed soil is more than 20cm, and the fertilized manure or compost 1500-2000 kg is applied as the base fertilizer, and then planted in the ridge.
2. Introduction and planting
At present, the cultivation of seeds in greenhouse trays has been successfully carried out, which can effectively increase the germination rate of white peony seeds, shorten the time of seedling formation of white peony, and rapidly obtain seedlings of white peony. At present, there are commercialized white peony seedlings for sale. This experiment was introduced to Henan Yunbang Agricultural Science and Technology Co., Ltd. When the roots of the seedlings grow to 3-5 cm long, they can be transplanted and colonized. The key to the survival of transplanted white peony is the size and vigor of the original bulb. Generally, the seedlings of the original bulb can be transplanted and survived, and the survival rate can reach over 95%.
3. Reproduction
White peony is generally propagated by underground tubers, and the sowing period is divided into autumn sowing and spring sowing. Before the autumn broadcast, the spring was broadcast before and after the Qingming. In the north, it is suitable for spring sowing. The stored white peony seeds are taken out and diced at the time of sowing, and the seeds are planted after the wounds are healed. The plant spacing is 30 cm × 20 cm, watering and protecting, in order to survive. When the autumn is planted, the white stalks that grow robust and free from pests and diseases can be selected in the autumn, cut into small pieces, each piece has 1-2 eyes, which is slightly cooler, so that the wound is healed and planted on the whole surface. .
4. Field management
(1) cultivating and weeding
The white stalk plant is short and can't hold the weeds, so pay attention to cultivating and weeding, usually 4 times a year. The first time after emergence in March-April; the second time in June when the growth is strong, so the weeds grow fast, the white seedlings are short, we must remove the weeds in time to avoid grass shortage; the third time in August-September The fourth time combined with the crops made in the harvesting room, the weeds were removed. Every time you have to cultivate, you should be shallow, so as not to hurt the buds.
(2) Water management
White carp is more like a damp environment, planting land needs to be kept moist, and timely watering in case of dry weather. In the dry season, spray water once in the morning and evening. The roots of the white pheasant are afraid of cockroaches. After the rain, the ditch will be drained in time to remove excess water and avoid rotten roots.
(3) Topdressing
White peony, fertilizer should be combined with cultivating and weeding 3-4 times a year. After the first time in March-April, the seedlings were applied with 4-5 kg ​​of ammonium sulfate per mu, and applied with decomposed and light manure; the second time was vigorously growing from May to June, and the calcium phosphate per acre was 30-40. Kg, mix well-cooked compost, spread on the side of the car, cultivating and mixing into the soil; the third time in August-September, per mu of manure and manure mixed with soil mixed fertilizer 2000-2500 kg.
(4) Intercropping with other crops
The plant is short, slow-growing, and has a long cultivation period. In the first two years, short-term crops such as radishes and vegetables can be planted between rows to make full use of the land and increase profits. The so-called intercropping refers to the planting method of planting two or more crops in a row or sub-zone in the same growing season in the same field. For example, in corn and sorghum, you can make andrographis, indigo, psoralen, and pinellia on its plants and ridges.
(5) Pest control
At present, no disease has been found in the cultivation of white peony, and only the main pests have been found to be underground pests. The larvae of the small ground tiger bite or bite off the white saplings and shoots, causing the vacancies to break, affecting the yield of white peony. 3-4 generations occur in a year, with larvae and pupa overwintering. In March-April, the adult moths are in full bloom, and April-May is the heaviest period of the first generation of larvae, and gradually reduced.
Control method: use the light or sweet and sour liquid to trap the adult in the adult period; the severely damaged plot can be artificially captured; use 50kg wheat bran and stir-fry with 90% trichlorfon 0.5kg to make poison bait, and use bait per acre. 5-6kg is used to trap larvae; before ploughing, chlorpyrifos granules or phoxim granules are applied, 2.0-2.5kg per mu.
(6) Winter protection
The lowest temperature in the central and southern parts of Hebei Province is around -12 °C. Therefore, it is necessary to take anti-freezing measures and cover them with crop straws, grass mats, etc., in order to facilitate the safe wintering of white peony.
5. Harvesting and processing
White peony is generally harvested after the stems and leaves of the ground in the autumn of 4 years after planting. Before harvesting, cut off the stems and leaves on the ground, then remove the underground roots, remove the soil, and put them into the basket. After soaking in the water for 1 hour, use the feet to step on the rough skin, wash and put in boiling water to cook 5-10. Min, when there is no white heart in the tuber, remove it and dry it or dry it for sale. The yield per mu is 150kg.
