Developing time difference (anti-seasonal) vegetables is an important way to increase the efficiency of growing vegetables. However, in the past, mentioning the time difference, most people sticked to the idea of ​​using a protective cultivation facility to artificially adjust the sowing date, thus staggering the time-to-market. However, due to the high investment in plant cultivation, high risk, and complex technical requirements, many vegetable farmers (especially new vegetable farmers in the adjustment of planting industry) are stunned. The “Little Shennong†spring lentils we introduced in 1999, relying only on its superior characteristics of being particularly precocious, made it impossible to add special facilities and complex technologies to produce time-varying vegetables in extensive cultivation and substantially increase the benefits to become a reality. It is welcomed by the vast number of peasants and town dwellers who leisurely grow vegetables in small courtyards. First, the characteristics of characteristics 1. Precocious old lentils in my county, are spring harvest. The small Shennong spring lentils can be harvested 50-60 days after sowing, and they will continue to flower and grow in the high temperature and rainy summer season until the frost falls. 2. Disease-resistant lentils used to be extensively planted in sporadic spaces, such as behind houses, fence walls, etc., and are rarely sick. "Little Shennong" spring lentils are also highly resistant to various diseases of the beans. 3. Drought-resistant root system is developed, deep into the earth, special drought, do not need frequent watering, different from other vegetables. 4. Provincial workers are less prone to disease, drought, and do not need complicated management. Therefore, the cultivation is more labor-saving, commonly known as "lazy dishes." 5. High-efficiency 667m2 can produce nymphal larvae 4000kg, and within 80 days from the start of harvesting, the old cultivars do not reach the time to market, "Little Shennong" spring lentils are the first to be listed in the open period, rare and valuable, the highest price Price has reached 10 yuan / kg, coupled with its low input, extensive management, so the higher overall efficiency. Second, the cultivation techniques 1. Soil fertility The variety is suitable for all kinds of soil, but the fertile loam is the best. Require deeper ploughing as soon as possible, re-application of basic fertilizer, usually 667m2 applied soil fertilizer 3000-5000kg. Before sowing, the application of potassium sulfate or compound fertilizer 50-75kg/667m2 may be repeated. 2. Timely sowing of "small Shennong" spring lentils can be cultivated in protected areas, but also can be planted in open fields. Planted in the open field can be sown at the depth of 5cm (14°C) in the depth (same as the cotton sowing date). In the early period, it was covered with a small shed, and it could be sown 10-15 days earlier. Seedling transplanting can be planted 25-30 days in advance, 2 leaves and 1 heart transplanted. Row spacing is 90cm, plant spacing is 40cm, sowing 2 or planting 2 plants per hole, and using 667m2 planting 1000-1200g. 3. If the vines are planted and cultivated, the 2.0-2.5m high shelving must be used before the height of 30cm. Sporadic planting, can use branches, bamboo poles, ropes, wire and other vines to climb the fence wall. 4. Pay attention to insect pests, spring lentils, spider mites, leafminers, and soybean mealworms. Abamectin can be used to treat the above pests. Special treatment of soybean meal, can also be used Cicipo 5mL + pyrethroid pesticide 10mL, water 15kg, sprayed before 10 o'clock in the morning, open a batch of flowers to spray a drug. 5. Top dressing After 3~4 batches of Nenjang, the fertilizer can be top-dressed once, and 20~30kg of potassium sulfate compound fertilizer is applied between the plants 20cm away from the stand. It is best to use topdressing fertilizer to pour water once. As lentils are leguminous crops, there are nodules and nitrogen can be fixed, so nitrogen fertilizers should not be used excessively, otherwise they may cause leggy. There are premature aging phenomenon, can also be sprayed outside the root potassium dihydrogen phosphate, photosynthetic fertilizer, fertilizer and other leaf fertilizers to treat.
