Tofu cultivation technology

1. Variety selection: According to the climate and site condition types, adherence to the principle of suitability in place, Pueraria has several companies in the township of Sanyang County to test their species and prove that it is suitable for planting in Southern Shaanxi. 2. Cultivation Techniques: The development of Pueraria lucidum should be followed in strict accordance with relevant regulations and standards for green food production, establish a standardized cultivation base, and produce natural, safe and nutritious GE green food raw materials. 1 Soil preparation and planting: High-yield cultivation grounds are fully turned into ridges, ridge height 15-20 cm, and ridge width 80-100 cm to facilitate drainage. Pueraria lobata is a shallow rooted woody vine, and the root system is mainly distributed in about 100 cm of soil. Therefore, it can be planted by means of ditch and hole planting. The ditch can be ditched in the center of the ridge with a width of 30 cm and a depth of 30 cm. The decomposed farmyard fertilizer is 1000-1500 kg/mu, fill it with soil to about 20 cm. The hole planting can dig a hole in the center of the ridge surface, the diameter of the hole is 30 cm, and the depth is about 30 cm. Each hole is rotated with 5-10 kg of rot, and the soil is filled with 20 cm of seedlings. Whether it is planting or planting, planting must be done. Deep planting and shallow burial, when the seedlings are planted, the seedling roots will be wetted, and the wet seedlings will be put into the pits so that the roots will naturally spread, the soil will be filled, the seedlings will be raised upwards, the seedlings will be exposed on the soil surface, the backfill will be practical, and the soil will be poured. After the root water and water infiltrate, the topsoil shall be covered in time. The topsoil is usually 4-5 cm. Ge Tengqiu planted spring can be planted in autumn, the need for planting on soil before freezing, spring planting should be early to prevent the spring warming up too quickly, the root has not yet been restored, the leaf has been expanded, steamed vines are too large, affecting the survival rate. 2 Planting density: According to the topography, soil quality, planting density of the plant spacing 80-100 centimeters, spacing 100-120 centimeters, acres planted about 556, but also can be closely planted, acres planted 800-1200 strains. 3 field management: Pueraria axillary buds rich, collateral development ability, leaving branch density and branches should be based on the degree of soil fertility and ventilation and light conditions, removal of weak skills, diseased branches. In order to obtain excellent yields, the branching density must be appropriate. Day-to-day management can be performed in winter or early spring, with a winter cut, leaving weaker than the root litchi, weak roots cut from the base, pests and diseases roots, dead side branches and dense side branches. Weeding and weeding are conducted 2-3 times a year to remove weeds and keep the soil loose. Since the root system of Pueraria is shallow, we should pay attention to shallow ploughing and weeding to avoid injury to roots and sprouts, especially when planting young seedlings, we must also timely cultivating and weeding. Baoxian seedlings are strong and healthy. Compound herbicides or plant growth regulators are strictly prohibited. The first seedlings should be watered according to the lyrics, and should not be short of water. During the growing season, the root soil should be kept moist, but it should not be drowned. When chemical fertilizers are applied, the fertilizers cannot be directly applied to the roots to avoid burning seedlings. There are relatively few pests and diseases of Pueraria lobata and there are mainly hazards such as ground tigers. Animal damage is mainly caused by rats, rabbits and wild boars, and attention is paid to killing. 4Pueraria lobata harvest:Pueraria lobata harvest suitable for autumn after the frost, the root starch content is high, when harvesting, can not damage the Getang cultivation ground, dig large and small, root excavation, interval rooting, fresh root yield control in 3000 About kilograms. After the harvest, timely delivery. High-yielding cultivation techniques 1 Rational fertilization Pueraria lobata is a kind of fertilizer-resistant plant. Applying basal fertilizer and reasonably applying fertilizer are important measures to increase tuber yield. The top dressing is usually carried out several times. For the first time in March to April, when the seedling height is 30 cm, 3 to 5 kg of livestock waste water is applied to each hole. After that, it is carried out once a month. The type and amount of fertilizer used are the first time. the same. The 4th and 5th sessions were conducted every 45 days. Each hole applied fertilizer, 10 kg of turf ash, 100 g of superphosphate, and 100 g of potassium sulfate. The above fertilizers were mixed and opened in the ditch or open hole next to the plants. Soil cultivation to promote root growth. 2 picking seedlings take a stand Pueraria has a strong budding force, planted Pueraria head often grow more stems. Excessive stem growth can affect the formation or growth of underground roots. Therefore, when the seedlings grow to 15 to 20 centimeters, only 1 to 2 strong seedlings are left per hole, and the others are removed. Pueraria lobata is a kind of windy grassy vine plant. The vines have many long sections, and when the sections touch the soil, it is easy to grow adventitious roots. Therefore, when the seedlings grow to 30 cm in length, bamboo or wood strips should be used to hold the scaffolds. The scaffolds can be fenced or cross-shaped, and the seedlings can be pulled up and wrapped around the scaffolds so that they can be easily managed and beneficial. Photosynthesis and air-transmission can also prevent stems from contacting the soil to produce adventitious roots and consume nutrients. The scaffolding should not be too late, too late vines intertwined, resulting in inconvenient management. 3 Picking the top of the inflorescence When the length of the stalk of Pueraria lobata grows to 200 cm, the top bud should be removed to promote its long branches and leaves, and enhance photosynthesis. However, too many branches will cause too many leaves and cover each other, affect the photosynthesis, but also make the stems and leaves consume too much nutrients, is not conducive to root growth. Therefore, excessive and dense foliage should also be properly removed. Between May and July each year, in addition to planting plants, the inflorescence that grows should be removed in batches in time in order to prevent excessive nutrient consumption during flowering, which is conducive to tuber nutrient accumulation and increase yield. 4 Rooting If plants grow too many roots, the accumulation of nutrients is not concentrated, so that the roots are not big, affecting the yield and quality. Therefore, after the tube root is formed to a diameter of 2 to 3 cm, the soil around the plant should be opened, and 2 to 3 thick tubers should be left. Others are removed so that nutrients are concentrated on 2 to 3 roots. To increase production.

Electric Under Blanket is a specific type of Electric Blanket, usually used in European countries. It is placed below the bottom bed sheet, but cannot be above the bed sheet or over human body.

It normally has 3 to 4 heat settings as option. Consumers can choose their suitable temperature ranges.

Electric under blanket is normally used for sleeping, hence it normally shut off after 12 hours, or be turned off manually.
