Cucumber bent melon is also called malformed melon, which is a physiological disease. The reasons for causing cucumbers to bend melons are as follows:
First, excessive leaf picking is easy to cause cucumber bending; second, too many single plants in the early stage; third, small flowers in the ovary when flowering, long quality is not good, even if flowering, the nutrients obtained later are less, easy It causes the curved melon; the fourth is the normal long-fruited melon strip, which takes a certain time when the fruit is inflated. If the condition is slightly bad, it will form a curved melon. Therefore, it is very important to use fertilizer in the later stage. Fifth, the initial growth of the results is normal melon, if the nutrients can not be supplied in time, will soon form a curved melon; sixth is the long fruit cucumber formed, when encountered in the expansion of the leaves encountered obstacles, will also form curved melon; It is caused by potassium deficiency and boron deficiency caused by high temperature. Generally, the daytime temperature should not exceed 32 degrees, and the daytime should be controlled between 25-30 degrees. Eight is sometimes too much or a single use of nitrogen fertilizer or chicken manure, pig cow dung, potassium fertilizer, phosphate fertilizer is insufficient, and cucumber cucumber is also prone to occur. Or other malformations.
Prevention and treatment methods: First, do not prematurely remove too much of the bottom leaves. The yield of cucumber depends mainly on the photosynthesis of the leaves to increase the yield. As long as the bottom leaves do not yellow, generally do not remove them too early, unless the bottom leaves are functionally prematurely aging, they can be removed.
In order to prevent premature senescence of cucumber leaves, it is necessary to use NPK and microbial fertilizers as well as multi-element mineral fertilizers and organic fertilizers in fertilization. In the early stage, organic fertilizers and NPK fertilizers have been used in the base fertilizer, and now it can be used per mu. 20 kg of microbial agents and 20-30 kg of multi-element mineral fertilizer were applied to promote the growth of cucumber roots, supplement nutrients, and prevent cucumber roots and premature senescence of leaves.
The second is: watering should be diligent, but the amount of watering should be less. The interval between watering in the high temperature period should not be too long. Do not exceed 32 degrees during the day. Generally, the daytime control is between 25-30 degrees;
The third is: the yield per plant cannot be too high, and the excessive yield per plant will increase the burden on the plant. In the early stage, if the melon is too much or the melon is not picked up, the leaves will age quickly and the bent melon will be formed easily.
The fourth is: timely removal of the bent bones that have occurred, you can also use the small stones to climb the bottom to make it straight; the other leaves can spray 200 times liquid compound microbial fertilizer or Shuofeng 481, spray once every 7 days 2-3 times, it has good control effect on the prevention and treatment of curved melon, sharp melon and big belly melon.

Extraction Kit Magnetics Bead Method
This standard specifies the terms and definitions, classification, technical requirements, test methods, identification, labels and instructions for use, packaging, transportation and storage of nucleic acid extraction kits (magnetic beads method) (hereinafter referred to as "kits"). This standard It is suitable for extracting and purifying human genomic nucleic acid and its fragments from various clinical samples such as serum, plasma, whole blood, cerebrospinal fluid, milk, saliva, urine, sputum, swab, tissue or paraffin-embedded tissue by magnetic bead method , Pathogen nucleic acid kit. Pathogen nucleic acid includes deoxyribonucleic acid (DNA), ribonucleic acid (RNA), etc. This standard does not apply to nucleic acid extraction reagents contained in closed systems that cannot extract nucleic acid extraction products for detection.
This kit uses magnetic beads with unique separation function and a unique buffer system to separate and purify high-quality virus from serum, plasma, lymph, cell-free body fluid, cell culture supernatant, urine or various virus preservation solutions DNA/RNA. The uniquely embedded magnetic beads have a strong affinity for nucleic acids under certain conditions, and when the conditions change, the magnetic beads release the adsorbed nucleic acids, which can achieve the purpose of rapid separation and purification of nucleic acids. The whole process is safe and convenient, and the extracted viral DNA/RNA has high yield, high purity, stable and reliable quality, and is especially suitable for automated extraction of high-throughput workstations. The nucleic acid purified by this kit can be applied to various routine operations, including RT-PCR, fluorescence quantitative PCR and other downstream experiments.
