However, because many farmers have improper methods of shacking, they often have poor stagnation effect or cause smoked seedlings. Let me introduce some technical points of high temperature shacks in vegetable greenhouses for your reference. Summer shack technical points 1, the shed before the Qingyuan disinfection The shack must be carried out after harvesting the fruits and vegetables in the shed. Before the shed, the roots, fruits and leaves of the plants in the shed, especially the diseased leaves and diseased fruits, must be completely and completely removed from the shed, and concentrated deep burial. Or burn it, don't throw it away, or just hang it out. After thoroughly completing the site preparation of the Qingyuan Garden, it is possible to use a avermectin-mixed sclerotium and other drugs to spray a comprehensive and uniform spray disinfection inside and outside the shed, corners and corners, and also to close the shed seal. The bactericidal agent such as bacteriological clearing is sterilized by shed sterilization, and if the disease is more serious, the dosage can be appropriately increased. 2, shack operation method When using high temperature and suffocating shed, use Weibaimu, lime nitrogen and other drugs to achieve better sterilizing effect. The farm manure can be transferred to the shed in advance before the high temperature suffocating shed, but the microbial fertilizer should not be applied to the ground in advance, and the mulch should be mulched and covered to avoid the use of flat mulch; When the temperature is high, the room temperature should be raised to 70 degrees or more, the surface soil temperature should reach 50 degrees, the new shed can be extended to 20 days, and the old shed can be extended to 20 days, so that it can effectively kill the hidden All kinds of soil-borne bacteria, pests and weeds in the soil in the shed have a remarkable effect especially on the control of root-worms, and at the same time can kill most of the spores, germs, eggs and eggs hidden in the farm manure. Larva and adult worms can also promote the decomposition of organic matter in the soil and avoid the burning of fat and roots. 3, shack attention After the stagnation of the pharmacy, it is necessary to carry out the ventilating and drying for 10 days in a timely manner, and all the harmful gases generated by the medicinal use in the shed are discharged out of the shed to avoid the late smoking of the seedlings due to the short ventilation time and the residue in the harmful gas shed. At the same time, high temperature shacks or smoked sheds will not only kill harmful bacteria and pests in the soil in the shed, but also kill the beneficial bacteria in the soil. Therefore, it should be applied as much as possible after the shack is over. Bacterial fertilizer and high quality organic fertilizer to promote the increase and activity of beneficial bacteria in the soil.
