Dry ridge crop ridge cultivation technology greatly increased production
A new method of crop cultivation - dryland crops ridge cultivation technology shows strong vitality in agricultural production. The Guangxi Agricultural Department organized experts to measure production. The corn planted with this technology increased yield by 25.60% compared with traditional planting (control), and peanut and soybean increased yield by 13.70% and 10% respectively.
Recently, Dai Jingrui, an academician of the Chinese Academy of Engineering and a professor at the China Agricultural University, said after a detailed understanding of the test situation: "This is a major change and innovation in farming methods. It is a major breakthrough in crop cultivation technology... Its development potential and utilization space are very large. ."
This dryland crop ridge cultivation technique was created by Wei Benhui, a researcher at the Economic Crops Research Institute of the Guangxi Academy of Agricultural Sciences, and his innovation team. On the basis of finding that the loose soil type of dryland crops is more than 15% higher than that of the knot and epithelial conjunctiva, they proposed this technique after a series of experiments. It uses a special tillage machine to smash the soil vertically and naturally suspend it into ridges. New cultivation techniques for direct sowing of crops. With this technology, traditional plowing, hoeing, hoeing, hoeing, hitting, and manual or mechanical smashing (carriage) can be completed once in the course of land preparation. It has the advantages of “easy operation, high labor saving, and can live and retain water. , ventilation and stimulation.
According to reports, the use of this technology, one can be based on the needs of crop growth, to achieve deep ploughing in the true sense, the depth of the ridge can be 30 ~ 60 cm (the yam crop can be about 100 cm), than the traditional plough preparation Obviously deepened, the clods are more finely divided, and the strips are carried out in the crop planting area. The ploughing and non-cultivation are separated, and the deep ploughing area generally accounts for 60% to 70% of the land area. The second is to activate soil quick-acting nutrients. It has been determined that the content of available nitrogen, phosphorus and potassium in the soil with a depth of 50-60 cm by powder ridge can be increased by about 20%, and the content of some trace elements is also increased. Third, a "U"-shaped trough-like long groove can be formed at the bottom of the ridge to facilitate the accumulation and utilization of natural precipitation. The fourth is to change the soil from the soil and reduce the weeds and plant diseases.
This technology has been tested in various crops in Wuming and Binyang, Guangxi, and has achieved remarkable results. On December 8th, 2009, the Agricultural Department of Guangxi organized the experts of China Agricultural University and Hunan Agricultural University to conduct on-site measurement of Wuming's tests on the use of powder ridge technology. Huaishan fresh potato yielded 3779.1 kg per mu; The yield of fresh potatoes per mu, Huanan 205, South China No. 8 and South China No. 10 reached 3,384.65 kg, 3,627.90 kg and 3481.95 kg, respectively, which were more than 30% higher than traditional cultivation. From July 19th to 20th this year, experts from Guangxi University and other units tested the production of powder ridge technology test sites in Binyang County. The yield of corn, peanuts and soybeans increased compared with traditional cultivation (control), and the yield increased by 25.60% and 13.70% respectively. And 10%. (He Gensheng)
The RT-PCR Test Reagent Kit is a real-time, RT-PCR test intended for the qualitative detection of nucleic acid from SARS-CoV-2 in oropharyngeal and nasopharyngeal swab specimens from individuals suspected of COVID-19 by their healthcare provider. This test is also for use with anterior nasal swab specimens that are collected using the COVID-19 Test Collection Kit when used consistent with its authorization.
Results are for the identification of SARS-CoV-2 RNA. The SARS-CoV-2 RNA is generally detectable in the upper respiratory specimens during the acute phase of infection.
Positive results are indicative of the presence of SARS-CoV-2 RNA; clinical correlation with patient history and other diagnostic information is necessary to determine patient infection status.
Positive results do not rule out bacterial infection or co-infection with other viruses. The agent detected may not be the definite cause of disease.
Negative results do not preclude SARS-CoV-2 infection and should not be used as the sole basis for patient management decisions. Negative results must be combined with clinical observations,patient history,and epidemiological information.
