Spring wheat how to fertilize?

Spring wheat fertilization, should be based on different types of wheat need fertilizer and wheat soil fertility, based on the application of organic fertilizers, the rational use of fertilizers, thereby increasing fertilizer utilization and reduce soil pollution.

How spring wheat fertilization

Generally high-yielding field control nitrogen, phosphorus, potassium, supplement micro, middle-yielding field nitrogen, increase phosphorus, targeted potash.

Wheat fertilization technology points:

1, high, middle wheat field

High-yield wheat field high level of soil, production conditions are good, successive years of nitrogen fertilizer input is too large, but relatively insufficient investment in potash. In the fertilization of organic fertilizer to increase the input, the full implementation of straw returning, in accordance with the principle of nitrogen and phosphorus by increasing the micro-micro-complement, high-yield wheat field (500kg / acre) Mushi organic fertilizer 4, nitrogen (N) 14 -17kg, phosphorus (P2O5) 8-10kg, potassium (K2O) 8-10kg; fertilizer on the bottom of the application of phosphate fertilizer, 30% nitrogen fertilizer at the end, 60% jointing stage, topdressing 10% 70% at the end of facilities, 30% jointing stage.

Middle crop wheat field Mushi organic fertilizer 3.5 square, pure nitrogen (N) 12-15kg, phosphorus (P2O5) 7-8kg, potassium (K2O) 5-8kg; fertilization on the top of 40% nitrogen fertilizer, 60% jointing stage, 70% potassium fertilizer at the end, 30% jointing stage, phosphate fertilizer at the end of facilities. Application of fertilizer on the optional zinc sulfate or manganese sulfate seed dressing, fertilizer per kilogram 2-4g. Spraying of potassium dihydrogen phosphate in the late wheat growth to increase the 1000-grain weight of wheat.

2, late broadcast wheat field

Late sowing wheat crop due to stubble late, delayed sowing, lack of accumulated temperature before winter, to heavy fat and seedling, in order to achieve the winter before the strong, the purpose of rapid conversion in spring. High-yielding fields Mushi 3 or more organic fertilizers, pure nitrogen (N) 14-15kg, potassium (K2O) 6-7kg, phosphorus (P2O5) 8-9kg; Middle field Mushi organic fertilizer more than 3 parties, pure nitrogen (N) 14kg, phosphorus (P2O5) 6-7kg, potassium (K2O) 5-6kg. Fertilization on the nitrogen fertilizer 40% -50%, bottom facilities, 60% -50% jointing stage topdressing, phosphorus and potassium fertilizer at the end of the next appropriate. In the late foliar application of multiple micronutrients. In addition, wheat cotton cover area due to greater consumption of potassium, may be appropriate to increase the amount of potash.

The above is the introduction of spring wheat fertilization technology, planting wheat friends, you can refer to the above fertilization techniques, combined with the actual planting situation, reasonable fertilization.
