First, apply enough base fertilizer. Late sowing wheat generally takes 10 to 15 days from sowing to emergence, and if the temperature is low, it will be longer, more than 20 days later than the timely planting of wheat. This shortens the growth time before the wheat seedlings, and the malt consumes the nutrients of the seeds due to the long time in the soil, causing the seedlings to grow thin. Therefore, the late-sown wheat must be strong and early, and the base fertilizer must be applied. The base fertilizer is mainly organic fertilizer, and the combination of nitrogen, phosphorus and potassium can produce 50 tons of mixed livestock and poultry fertilizer per acre, 40 kilograms of ammonium sulfate, 30 kilograms of superphosphate, and 10 kilograms of potassium chloride.
Second, early application of seedlings. Late-sown wheat has poor vegetative growth. Before winter, the main stem has only 3 to 4 leaves, and most of the wheat seedlings cannot be divided before winter. Therefore, around the winter and promote the early development, it is necessary to apply the seedling fertilizer early, so as to see the buds. Apply 10-15 kg of ammonium bicarbonate per acre, 20 to 30 liters of rare manure, or 60 to 80 ton of pond mud. If it is difficult to prepare seedlings after long-term drought after sowing, it is necessary to promote the seedlings early, and combine the drought-resistant application of seedling fertilizer to dilute the manure. Cold soaking and staining paddy fields should be protected against deadlocks and prevent the occurrence of stagnant growth stagnation. The anti-fungal fertilizer is mainly made of superphosphate, 10-15 kg per mu, and it should be combined with seedling fertilization.
Third, chasing the wax fertilizer. Late-sown wheat has a small green leaf area before winter, and there are few photosynthetic products. The wheat seedlings have less sugar storage and poor cold resistance, and are susceptible to low temperature freezing damage. Therefore, for the lack of organic fertilizer, the thin field of wheat seedlings should be applied to the fertilizer to facilitate safe wintering. Generally, 50 tons of pig manure per acre is applied to the wheat line, and 10 kilograms of urea can also be applied.
Fourth, skillfully return to the green fertilizer. In order to stabilize the growth of wheat seedlings and increase the rate of ear formation, it is necessary to see Miao Qiao returning to the green fertilizer at the end of spring. The application rate is generally 6 to 10 kg of ammonium bicarbonate per acre, or 10 to 15 liters of human excrement. For wheat seedlings with obvious yellowing and severe freezing damage, the amount of fertilizer can be appropriately increased. In addition, the effective tillering of late wheat is late at night, 15 to 30 days later than the timely sowing. If the appropriate amount of green fertilizer is applied, it will be good for the early spring to divide into ear, but it is not too late to fertilize too much.
Fifth, heavy application of jointing and panicle fertilizer. In order to reduce the degradation of florets, late-sown wheat should be re-applied to the jointing fertilizer. About 10 kilograms of ammonium sulfate is used in two acres. When fertilizing, it is necessary to look at the seedlings. Miaowang and leaf color can be applied less; the group is small and the leaves are lightly colored, but the leaf color can be faded when the mouth is expected to break.
Sixth, increase the application of root fertilizer. It is an effective measure to increase the grain weight and increase the grain weight. Because of the late growth of late-sown wheat, the root absorption capacity is weakened, and the leaves are prone to yellow premature aging when the fertilizer is lacking. Therefore, late sowing wheat in the initial stage of the beginning of the grain to the first stage of grain filling, the use of potassium dihydrogen phosphate 100 ~ 150 grams, or superphosphate calcium 1.0 ~ 1.5 kg of filtrate with water 75 kg, sprayed in the evening foliage, is conducive to increase production and income .
Second, early application of seedlings. Late-sown wheat has poor vegetative growth. Before winter, the main stem has only 3 to 4 leaves, and most of the wheat seedlings cannot be divided before winter. Therefore, around the winter and promote the early development, it is necessary to apply the seedling fertilizer early, so as to see the buds. Apply 10-15 kg of ammonium bicarbonate per acre, 20 to 30 liters of rare manure, or 60 to 80 ton of pond mud.
