Huang Hongma seedling management technology
The yellow seedlings grow slowly, have poor stress resistance, and are vulnerable to drought, heavy rain, flooding, low temperature, weeds, diseases and insect pests and other disasters, resulting in rot, yellow leaves and dead seedlings. Therefore, the small red mandarin planting about the red hemp, must strengthen the seedlings to ensure that the whole seedlings seedlings and early growth. Specific measures are: 1. Dingling seedlings in the morning: Timely seedlings and seedlings are the key measures to ensure that early seedling growth is achieved on a whole seedling basis. Generally, the seedlings should be seeded once or twice, so that the leaves between the seedlings do not overlap. When the seedlings are 6.6-10 cm, they should be seeded according to the prescribed density. Simultaneously with seedlings and seedlings, combined with seedlings to make up for deficiencies and timely transplanting to ensure seedlings and seedlings. 2, early prevention and control of pests: more rain at seedling stage, prone to erection, anthrax, and ground tigers, aphids and other hazards. Diseases can be treated with 1000 times of dry fungicide, extermination of disease, green magnifier No.1, cardiformin, etc. The insect pests can be sprayed with 1000 times of kung fu, all spirits, dilutions, exterminations, etc., such as pests and diseases, In any of the above-mentioned pests and pesticides, they are arbitrarily selected, and as the mixture is followed by spraying, there are also miraculous effects. 3. Early fertilizer application: After setting the seedlings (30 days after emergence), apply 6-8 kg of urea per acre (irrigation of drought and water supply) in order to promote its early growth and long-term use. Advantageous absorption, accelerating the rapid elongation of the stalks, erecting a good harvest posture. 4, early Qing ditch row stains: Huang Hongma's most afraid of the seedlings, a water, it will lead to rot yellow leaves and dead seedlings, and the seedling period coincides with the province's rainy season, so we must regularly clean up three The ditch is in place to ensure that the water can be drained and dark stains can be filtered to achieve the effect of rain and dry weather. Especially in the low-humidity areas, paddy fields, and floodplain plants, it should be prevented and reduced damages as soon as possible.
