Wheat field management technology in jointing stage
First, fertilization
1, from the fat: Where the early growth of wheat is insufficient, the low density of weak seedlings must be timely to recover from body fat, generally 10-15 days before jointing to recover urea 7 kg; strong seedlings, Wang Miao do not apply fertilizer.
2, jointing fertilizer: application of the number of varieties and the fertility of the plant and the early growth of the plant, has reached the standard seedlings per acre can recover 35 kg of urea; Wang Miao not Shi, weak seedlings appropriate increase.
3, pregnant panicle fat: Where there is no application of joint fertilizer, booting has a lack of fertilizer symptoms, it is necessary to apply panicle and fertilizer. When the flag leaf is exposed, 23 kg of urea is collected per mu.
Second, drought and stain
The waterlogging of wheat is caused by surface water, shallow water and groundwater, and shallow water is the most harmful. Therefore, it is necessary to reach a straight ditch at the end of the ditch, so that the ditch and ditch can communicate with each other, so that the rain will stay dry, the rain will be clear, the dark water will be drained, the groundwater will be reduced, and the conditions for soil ventilation will be improved. This will create a good soil environment for the growth of wheat under rainy conditions.
Third, prevent lodging
Lodging of wheat mostly occurs after heading, but the cause of lodging is formed from jointing to booting. When the middle and high fertility and high density plots begin to elongate between the first internodes of the wheat base, 15 acres per mu are used. % of paclobutrazol WP 8 grams, sprayed 75 kilograms of water, can play a dwarf effect, while promoting production.
IV. Pest control
Mainly to prevent wheat scab, rust, powdery mildew and armyworm, aphids and other hazards, but also pay attention to the prevention and treatment of rats, birds harm, we must also pay attention to remove the weeds around the field. Http://
