How to manage the seedling stage of Ma Yam?

How to manage the seedling stage of Ma Yam? Please introduce the management methods for planting yam at the seedling stage, you can refer to the following methods for management: first, insert frame and frame material disinfect Ma yam takes 25 May 35 days from sowing to emergence, this time is mainly to insert the frame, the insertion frame uses three bamboo poles at the edge to inward, the fourth in the opposite direction, and then press one inward and one outward cross direction to insert the rack, and then tie it up. If the bamboo pole used as frame material is not bought in the same year, it also needs to be disinfected. First, remove the yam vines that remain on the bamboo pole, and then spray the bamboo pole with 50% carbendazim or 1.5% thiamidone 300 Mel 500 times liquid, in order to kill the residual bacteria and control leaf diseases. 2. To prevent and cure the blind bug bug, there are 20 insects in 100 plants, and when the damaged plants reach 3%, they should be sprayed with 1000 times liquid per mu or 15 grams of imidacloprid and 30 kg water, or 1000 times solution of hyperosmotic avermectin. In addition, we should pay attention to the spraying time, because the bug bug sleeps day and night, so spray before 9: 00 in the morning or after 5: 00 in the afternoon, in order to achieve a better control effect. Third, timely watering and fertilizing yam is drought-resistant, wet and afraid of flooding. The first water should be irrigated in mid-June according to soil moisture, weather and seedling conditions to ensure the water needed for the normal growth of yam. Before sowing, shallow soil cultivation should be carried out after seedling emergence to prevent premature root senescence, combined with watering the first water to control nematodes, Shennongdan 3 should be used to control nematodes, 5kg of Shennongdan 3 should be used to control nematodes per mu, and it should be sprinkled when the water seems to be osmotic and non-permeable; in the middle of July, the first topdressing should be carried out combined with the second water. 50 kg of special fertilizer for topdressing hemp yam, or 50 kg of Sakefu. Pay attention to the watering time should be controlled after 5: 00 p.m. to 10: 00 a.m. the next day, do not cause root stimulation caused by watering at noon. 4. Chemical control should be carried out according to the growth situation after the stem vine of Chinese yam climbs to the top of chrysanthemum. The prosperous mu should be sprayed with paclobutrazol 20g in water and 15ml in 30kg, spray the young stem slightly, and then spray it every 10mu every 15 days. The peak growth period of stem vine is from July 20th to August 30th. According to variety, soil fertility and growth situation, you can spray tender tip with paclobutrazol 40g / mu and water 30kg / mu. Generally speaking, chemical control should be stopped after September 10. Pay attention to the chemical control of paclobutrazol should be configured separately, so as not to affect the efficacy; the best time is after 10:00, before 5pm; re-spray in case of rain within 4 hours after spraying.
