The formation of Pinellia yield mainly has the following two factors, one is the enlargement of the stem of the stem itself; the other is the formation of the buds sooner or later, the number, the size, the algebra and the coefficient of expansion. How to carry out planting and management reasonably so that it meets the conditions required for the above production. The excellent seeds are an important guarantee for the high yield of the Pinellia plantation. So choosing a good breed is a key step. Heze Huahai Space Breeding Co., Ltd. undertook the completed Pinellia spp. breeding and hybridization technology project. The successful development of Leize Pinellia yielded more than 30% of the traditional varieties, and not only produced large quantities of fine Pinellia seedlings, but also shortened the field. Growth period. In combination with bud and tuber propagation, the propagation coefficient is increased. The Pinellia genus has strong fertility, is able to withstand cold, is not tolerant to drought, and avoids exposure to the sun. It is warm and humid in Banxiaxi. It grows in sandy lofts. It can be seen in the front of the house, behind the mountain stream, and under the forest. In summer, it is advisable to use leguminous and corn in the former. Pinellia does not require strict soil requirements. In addition to saline and alkaline land, the soil can generally be suitable for sandy soil. According to the biological characteristics of Pinellia, the production should be developed according to local conditions. Pinellia can be interplanted in gentle slopes and semi-yin and yang slopes, or in wheat or broad-leaved fruit trees. It can also be interspersed with high-stalked plants such as corn, canola, sorghum, and beans, so that it can manage crops or economic fruit. The management of Pinellia not only makes rational use of the land, but also increases the overall benefits. The suitable temperature for growth of Pinellia ternate is 23°C～29°C. When the average ground temperature is about 10°C, Pinellia ternata germinates. When the average temperature reaches 15°C～27°C, Pinellia ternata grows most vigorously. In early spring, the seedlings are preliminarily planted under the conditions of 20-25°C, and when most of the coleoptiles are white, they are planted and covered with mulching film. This results in earlier emergence of the seedlings than that of neither pregerminating nor film-mulching. Before the internal physiological changes, the cover film increased the ground temperature and reached the required temperature for seedlings in advance, and the shoots soon grew out of the ground. In addition to warming the seedlings in advance, they also loosen the soil and have good air permeability. They are also more conducive to the growth and development of the root system, make the plants more resistant to drought, and have always maintained a strong absorption function and physiological function. It is a tuber of Pinellia tuber. Increase the foundation for high yields. In most parts of China, starting in July, as the temperature rises, the maximum temperature often exceeds 35°C, and the growth of the Pinellia sinensis is severely affected. Pinellia is not tolerant to drought and prefers to grow in high-humidity soils. Keeping the surface wet and delaying the withering time of the Pinellia terrestris as much as possible is an important measure to increase Pinellia yield. Rice and wheat straw were covered in mid-May and mid-June each year. In the late July, only 5% of the seedlings fell, showing good growth, while the control group had 78% of seedlings. In this way, the coverage is relatively prolonged, the photosynthesis period is relatively prolonged, photosynthetic products are accumulated in the tubers, and the produced tubers grow large and the yield is high. The coverage of weeds in the covered area was significantly lower than that in the uncovered control area, and the incidence of leaf rot was significantly reduced. This is also an important reason for Pinellia yield increase. If the rainfall is large, the rainy season is cloudy and rainy, excessive soil moisture should promptly remove the covered wheat straw to prevent underground tuber rot to reduce production. Spraying sodium sulfite solution during high temperature and dry period can increase Pinellia yield. Because Pinellia in summer temperatures continue to be as high as 30 °C, due to high temperatures and strong light, Pinellia's respiration is too strong, the material consumed is more than the accumulation of photosynthetic substances, leading to the destruction of the cellular protoplasm structure and "down seedlings." As far as Pinellia production is concerned, “down seedlings†has shortened the growth period of Pinellia sinensis and seriously affected Pinellia's yield. Therefore, taking measures to delay or reduce Pinellia summer in production is an important condition for realizing Pinellia's high yield and quality. In addition to proper shade and water spray irrigation to reduce light intensity, air temperature and ground temperature, plant respiratory inhibitor sodium sulfite 0.01% solution can also be sprayed, and 0.01% sodium sulfite and 0.2% urea and 2% superphosphate can also be sprayed. The mixed liquor can restrain the respiration of Pinellia terrestris and reduce the consumption of photosynthetic products, thereby delaying and reducing the "backward seedlings", and can achieve significant yield increase benefits. Pearl shoots need to grow soil, so in June and July in the lower part of the petiole soil, top dressing 2 times, apply 7500 to 15000 kg per hectare of fertilizer, or thin human waste, each soil from the rows of soil to collect beads, soil 1.6 Above centimeters, weeding is often done during the growing season. Except for seeds, the buds growing during the growing period are all removed, which promotes tuber growth and enlarges yield. 3ml Disposable Medical Sterile Syringe This product is made of barrel , plunger ,piston and needle.This barrel should be clean and transparent enough to easy observe.Barrel and piston matches well and it has a good property of sliding,and is easy to be used. 3ml Disposable Medical Sterile Syringe;Syringe Factory In China;Medical Used Syringe With CE And ISO Changzhou Yuandong Medical Equipments Co.,Ltd , https://www.czydmedical.com
