First, choose good breeds. According to the classification of peas, hard peas, ie peas for grains, generally only eat green peas; soft peas, ie peas for pods, are soft and edible. Some peas have edible young shoots or young shoots. Some can be used for feeding or green manure. The main varieties are described as follows: 1. White peas: Hard pods, plant height 70-200 cm, robust growth, light green leaves, flowering from the 10th, each with 2 flowers (double pods), white flowers, èš6 cm long, 1.5 cm wide, 4-5 seeds per pod, mature seeds round and smooth, light yellow. Stripping tender seeds for food, produce 400-500 kilograms of soft bean pods and 100-150 kilograms of dried beans. 2. Zhongwan No. 4: Hard pupa species, stem dwarfs erect, plant height 55 cm, leaves light green, white flowers, pod length 8 cm, width 1.2 cm, grain yellow-white, one hundred grain weight 23 grams, tender bean green, For early maturing varieties. The yield of green pea pods is 600-800 kilograms and dry bean seeds are 150-200 kilograms. 3. Zhongya No. 6: Hard aphid species, plant height 40-50 cm, dark green stems and leaves, white flowers, 7-10 axils of one plant, 7.9 cm in length, 1.2 cm in axillary width, large and full capsules, dry The beans have a light green color and the weight of one hundred grains is 25 grams. The yield per mu is 600-800 kilograms, and the dried bean seeds are about 200 kilograms. 4, the Netherlands beans: soft pod species, plant height 150-200 cm, light green leaves, purple flowers, 7.5 centimeters long, 1.5 centimeters wide, tender green, brown tan, late-maturing varieties, fresh produce 350 kg per mu. 5. Food and vegetables pea No. 1: soft quail species, plant height 70 cm, white flower, pod length 16 cm, width 3 cm, sword-shaped, 5-6 pods per plant, up to 10 pods, 5-6 capsules per pod Seeds, white grain, flat side, grain weight 31 grams, stem diameter, section density, large leaves, compact plant shape, growth period of 188 days, 700-1000 kilograms per mu yield. 6, no need to bean No. 1: special varieties of pea sprouts, vines, hard pods, plant height 130 cm, white flowers, lobular leaves of the compound and the top without tendrils, leaves large fleshy, green color, do dishes have a special fragrance, Quality is better than local varieties. The grain is white, oblate, and the grain weight is 30 grams. 7, the United States Bean sprouts: is specifically for picking young shoots or shoots of pea varieties, tender and delicate, nutritious, plant height 185-195 cm, complex leaves tendrils, leaves smaller, white flowers, good quality, high yield , More cold-resistant, not heat-resistant, autumn planting 800 kg (nuo shoots). Second, deep plowing, practice rotation. Peas bogey continuous cropping, due to pea roots secrete toxic substances affect fertility; excessive secretion of organic acids affect rhizobia fertility, aggravation of pests and other reasons, so planted peas land, to be separated by 4-5 years before replanting. Deep plowing and finishing to create soil conditions suitable for the growth and development of pea roots and root nodules. According to variety characteristics, soil drainage status, vegetable high culm variety 1.5 m (Liangou) species 2 lines, grain high straw 2 m (Liangou) species 4 rows, dwarf 2.5-3.5 m (Liangou) species 6 lines. Third, the appropriate sowing. Pea sowing is in mid-to-late October. General planting density 40 cm 20 cm, about 10,000 holes per mu. High-stem varieties should have lower density than dwarf varieties; seedling density can be increased or seedlings can be used. Seeds of 2-3 seeds per hole, 5-75 kilograms per acre. The vegetables are stalked soft pod peas, tall stalked sweet peas, spacing 70-80 cm, spacing 30 cm, and easy to manage picking. Early peas, such as Zhongwan No.4 and No.6, were planted in late November. They were planted in 10 mu per mu and were planted at a spacing of 30-35 cm and 10-15 cm with 2-3 seeds per hole. Fourth, apply basal fertilizer. Before sowing, Mushi is generally used to produce 2500 kg of manure, 25-30 kg of superphosphate, 10-15 kg of potassium chloride, and a large amount of organic fertilizer. You can also use ternary compound fertilizer 30-40 kg points, but can not touch the seeds. Fifth, field management. Immediately after the emergence of seedlings to fill the shortage. Cultivate weeds 1-2 times to loosen the soil and eliminate weeds. Pay attention to topdressing during seedling production, especially for those that have not applied or used less base fertilizer, generally applying 5-7.5 kg of compound fertilizer or 5 kg of urea or 1,000 kg of decomposed human waste per acre to promote the early formation of seedling growth and root nodule. After the temperature rises in the spring, when the plants begin to elongate, the tall stalks are planted with branches or branches with branches (to be removed) to allow the pea plants to climb upright and increase yield. The peas are not resistant to water stains and do a clean ditch drainage work in spring so that there is no water in the ditch. When the pea blossoms and scabs, due to the need for more nutrients, 7.5 kg of urea is topdressed with 5 kg of Sanyuan compound fertilizer. During the grain phase, extra-root topdressing can be performed twice with 0.3% urea solution and potassium dihydrogen phosphate solution. Six, timely harvest quality assurance. According to the different ways of eating peas, decide the harvest time to ensure the quality of food. Generally grain peas are harvested 15-18 days after flowering, when the grain is full. Dried peas 70-80% pods harvested when yellow. Vegetable peas (Dutch peas) were harvested 12-14 days after flowering of the pods and harvested when the pods were not present. Mature batches were harvested and harvested. Pea seedlings are sown about 30 centimeters after they are sown, and shoot height is about 18 centimeters. The shoots are picked on top and then used every 10 days or so for a total of 6-7 times. The peas used as feed were harvested at flowering stage (75% of the plants were flowered) and the plants were rich in nutrients. The peas used as green manure were rolled over in time after harvesting fruit.
Upper limb locking plate system consists of ulna radius locking plates,humerus locking plates,clavicle locking plates,scapula locking plates,locking screw and cortical screw.
The locking plate also has locking or non-locking screw holes for different trauma screws.In the internal fixation of the upper limb, four locking screws are generally used, which are mainly divided into 2.7mm and 3.5mm diameter.
