After the cover film is inspected by Cha Tin, it is necessary to have a special person to inspect the field protection film, and if it is found that the wind-breaking uncovers the film or the film is damaged and windy, it shall be tightly and firmly sealed with the soil.
Seedlings were first planted after the membrane was broken. After the peanut seedlings were unearthed, the top mulch of the seedlings was scratched in the morning or evening with a knife to expose the seedlings to the outside of the membrane to prevent burning of the seedlings; After 7 days, when the top soil of the seedlings is about to emerge, the soil on the membrane hole will be gently opened to the surrounding and the seedlings will be exhumed to prevent nesting.
Clearing trees and replanting will open up the surrounding soil around the seedlings' rhizosphere and expose the cotyledons to the outside of the membrane. At the same time, it is necessary to carefully press the membrane pores with soil. Where there is a shortage of seedlings, germination should be promptly made and water must be planted.
After cultivating weeds and rainfall and watering, we must promptly go through shallow ditch, break the compaction, and prevent weeds from breeding.
Drought prevention and drainage When the absolute water content of 10-20 cm soil is lower than 10%, it is necessary to drench the small water and it is forbidden to flood irrigation. During the period from early June to late July, when the vegetative growth and reproductive growth of peanut covered with plastic film are in an advanced stage, attention should be paid to drought irrigation. When there is a lot of rain in July-August, pay attention to clearing the wells in the field and do a good job of removing water from the water.
Appropriate rhizosphere topdressing and foliar spray fertilizer mulching can easily result in weak early growth, slow growth in the medium term, and premature aging of defertilization in the later stages. It should be applied according to the seedling rhizosphere boring, that is, after the initial flowering period, an eye-puller or wooden stick is used. Close to the plant 5 cm to drill 5-6 cm deep fertilization, applied per acre 15-20 kg of ammonium sulfate or urea 10 kg and 30-35 kg of calcium sulfate, chase after the use of soil pressure.
Controlling the length of plots where there is a tendency for vegetative growth in the shoots can be controlled by paclobutrazol. Generally in the flowering period, when the plant height is about 35 centimeters, 15% paclobutrazol 20-30 grams per mu, plus 25-40 kg of water spray.
In addition, attention must be paid to the prevention and control of stem rot, leaf spot, aphids, and spider mites.
