Peas can also be called green beans, wheat peas, cold beans, wheat beans, snow beans, bidou, hemp, etc. They are annual or overage herbaceous plants, mainly distributed in Qinghai, Ningxia, Shandong, Inner Mongolia, Sichuan, Jiangsu and Zhejiang. Other provinces are one of the most common vegetables in our lives. Today's Xiaobian is about pea planting time and planting techniques. First, the cultivation time of peas Pea is a four-season vegetable, so it can be planted all year round. During planting, the sowing date can be flexibly controlled according to the mouthwash and season, and the suitable sowing date can be determined according to the time requirement of the pod market. The relationship between the pea sowing period and the harvest time is as follows: Autumn sunshade net shed cultivation in early August - end of August - October 1st, autumn open field cultivation in late August - mid-September - mid-October, winter film greenhouse cultivation in October - February New Year's Day, winter open field cultivation 11 Month--January 1, January 1st, spring open field cultivation from February to April, mid-May, summer open field cultivation in early May - late May and late June, summer shade net shed cultivation in mid-May - 6 Mid-July in early July. Second, pea cultivation techniques (1) Seeding method Seeding methods can be selected by on-demand, spreading, and seeding. The line spacing is 35 cm, the plant spacing is 10 cm, 2 to 3 capsules per hole, and the seed amount is 10 to 20 kg. The seeding amount is 15-20 kg, and the general use of the seeding method is the most. Good, because this method not only saves seeds, facilitates weeding, but also facilitates fertilization and green bean pod harvesting. When using the strip, the standard plan is 30cm in width and 1.5m in width on the whole ground. According to the specifications of 0.15m wide and 0.25m wide, the soil will be covered after the sowing. The number of sown seeds is controlled at 37,000 to 43,000. (2) Rational fertilization In the preparation of the land, about 1000 kilograms of manure per acre of land; when planting, use 45% of ternary compound fertilizer 20 kilograms or 25 kilograms of calcium magnesium phosphate fertilizer to plant in the sowing ditch or planting width; when about 70% of seedlings, use per acre 5 kg of ammonium sulphate or 10 kg of urea is applied to water or before rainfall; in the initial stage of flowering and pod-forming, 10 kg of ammonium sulphate or 15 kg of urea is poured per acre of ground; if the conditions of the grouting granules are allowed, The top dressing of the roots is applied to 40 kg of water per 100 mu of potassium dihydrogen phosphate to increase the grain weight. (3) Chemical weeding Before sowing, use 50% acetochlor 100 ml or 20% dichlorfen 200 ml per acre to spray 50 kg of water on the whole field. After spraying, it is forbidden to trample the human soil to destroy the soil layer. (4) Pest control Pea pests and diseases occur relatively lightly. If pests and diseases occur, you can use 10% imidacloprid 20g to kill 6ml to kill leaf miners, aphids and cabbage caterpillars. In the case of pest control, you can add 75% chlorothalonil 75-100g while controlling diseases. . (5) Picking at the right time The peas are mainly picked as granules. When the grains are full and the shell color is slightly diminished, the peas can be harvested in batches. When harvesting, the peas should be held in the left hand to prevent loss of the bean plants.
It can be used for surgical operations, patient treatment; epidemic prevention and inspection in public places; disinfection in virus-contaminated areas; and can also be widely used in military, medical, chemical, environmental protection, transportation, epidemic prevention and other field
By setting a protective collar, the neck of the operator can be kept warm and protected. The provision of a hand guard is helpful for the surgical staff to temporarily place their hands in the hand guard while waiting during the operation, which plays a protective role and is more in line with the principles of aseptic operation and occupational protection. surgical gown,disposable surgical gown,personal protection,medical equipment Shanghai Rocatti Biotechnology Co.,Ltd , https://www.ljdmedicals.com
By setting the shrinking cuffs, it is beneficial to make the cuffs fit the wrists, prevent the cuffs from loosening, and prevent the gloves from slipping off during the operation and the operator's hands are exposed to the gloves.
The design of the new humanized protective surgical gown has been improved in the key areas of the gown. The forearm and chest area are double-thickened, and there are handguards in front of the chest and abdomen. By arranging reinforcing sheets (double-layer structure) in key areas, it is beneficial to improve the water-permeability of surgical gowns and improve safety.
