This technology is suitable for local promotion and application of water resources guarantee, and it should be time-difference between the late spring crop harvesting period and the spring cropping period for interplanting. The following aspects should be mainly grasped:
1. Timely planting sowing too early, flue-cured tobacco is not harvested in time, a long symbiotic period, affecting the pea production, too late, when the frost frozen soybean meal was frozen, combined with a short harvest period, affecting quality and yield. Timely sowing to ensure the harvest time of peas can increase the yield. It can be sown after the second shed tobacco is harvested from the flue-cured tobacco, that is, the most suitable sowing date from late July to early August. If the flue-cured tobacco is harvested, it can be sowed in advance. .
2. The method can properly use the post-effect of the film and fertilizer of flue-cured tobacco. Between each two rows of flue-cured tobacco, the seed is sown and the seed is sown. Then, the seeds and the film are pressed with fine soil. Sowing can be taken in ponds (holes) or broadcast.
3. Mastering density and close planting is an important measure to increase production. Tobacco planting and interplanting maintains the original spacing, which is generally 1 meter, and the distance between the ponds is 20 centimeters. (Three empty ponds of flue-cured tobacco are sown, and the distance from the rods is appropriate), and 4 to 5 seeds per pond. Drilling every 3 to 4 centimeters a seed, mu sowing 3 to 4 kg. Pond sowing 3000 ponds per mu, basic seedlings guarantee 8000 to 9000 strains.
4. Measure to keep up with the selected species is not dwarfed. After the flue-cured tobacco was harvested, the dwarf species used a rod of tobacco as a support, the tobacco rod needed to be 70-80 cm or more, and a rope was pulled horizontally at the top. Sprawling species need to use another bamboo pole or other two-meter-high rack to form a “human†frame or a fence frame, and pull three ropes horizontally. At the same time, it is necessary to manually pull the line to pull the shelves. The shelves should not be late as soon as possible. Winding, lodging, affecting growth.
5. Timely irrigation of top-dressing pea seedlings has a certain drought tolerance, but the flowering and podling period can not be short of water, should be simultaneously irrigation and fertilization. 5 leaf stage (15 to 20 cm seedling height), topdressing nitrogen fertilizer, usually 5 to 10 kg of urea or 10 to 15 kg ammonium nitrate, followed by topdressing compound fertilizer. According to the harvest period of peas is generally 60 to 65 days, the entire growth cycle should be topdressing 5 to 7 times, began to collect once a week after harvest, each time about 10 kilograms watering, water management to do see see wet .
