Corn increases production without pesticides
When you think of increasing production, you think of pesticides. Now that production increases are generally done with pesticides. Here are some ways to introduce to you: promote seedling transplanting, both provincial and increase production. Transplanting corn seedlings is a good measure to save seed and increase yield. With seedling transplanting, 1 kg of selected seed memo can meet the needs of an acre field, which can save 1 kg to 2 kg of seed than general seeding. At the same time, the seedlings transplanted and planted were short-sturdy, with multiple secondary roots, low panicles, drought resistance, and lodging resistance, which were more than 10% higher than those of live summer corn. Seedling time: When the seedling age reached 6-8 leaves, it was transplanted and the seedlings were grown 20 days to 25 days before. The seedlings should be finely screeded and full-grown, and the base fertilizer should be applied. The spacing should be 18 cm to 23 cm and the spacing between 6 cm and 9 cm. The seeds should be sowed. After sowing, the cover soil should be 3 cm to 4 cm. When the seedlings grow two leaves, they combine with Dingmiao to clear the earth. Three days before transplanting, the secondary roots were raised by light irrigation, and the seedlings were raised to protect the secondary roots, so as to ensure that they would quickly grow into robust growth after planting. When planting, the seedlings shall be transplanted separately according to the size and size, and the seedlings shall not be mixed to prevent seedlings from sprouting. It is best to choose cloudy or sunny afternoon transplanting, open the ditch according to the predetermined spacing, with the ditch with the seedlings with transplanting, seedlings close to the ditch after righting the cover soil 3 cm -4 cm, with the plant with watering, the next day Then ditch a ditch, and other water infiltration, along the ditch to recover a standard nitrogen fertilizer 10 kg per acre, and then cover the flat ditch, and timely cultivation of loose soil, promote seedlings early and long hair. Some of the techniques used to grow crops that do not necessarily use pesticides can also achieve this effect.
