In the process of planting wheat, fertilization is one of the very important links. It not only affects the healthy growth of wheat, but also affects the yield of wheat and the economic benefits of planting. Therefore, Xiaobian will briefly talk about the low cost of wheat and wheat. The harvesting point of harvest - scientific fertilization, I hope to help everyone.
[North China Rain-Farming Winter Wheat Region: North of the Huaihe River in Jiangsu and Anhui Provinces, Southeastern Henan Province]
First, the principle of fertilization
(1) Before the wheat is returned to the green, the combination of repression and cultivating and arable, and the measures of soil moisture, seedling transformation and drought resistance.
(2) Wheat fertilization along: a small number of layers.
Second, fertilization advice
(1) Apply fertilizer or shovel strips, apply 5-7kg of urea per mu of land and cover the soil.
In the phosphate-deficient field, 7-10 kg of diammonium phosphate is used per mu, and the potassium-deficient plot is applied to 15-20 kg of nitrogen-potassium compound fertilizer.
(2) 7-10 kg of diammonium phosphate per acre in the phosphate-deficient field, and 15-20 kg of nitrogen-potassium compound fertilizer in the potassium-deficient plot.
(3) Wheat or corn stalks are covered between rows before the wheat is sealed to reduce the evaporation loss of soil moisture.
(4) When the winter is dry, timely manage the fertilizer and water, and apply urea 5-8 kg/mu per mu.
(5) Do a good job in the prevention and control of sheath blight and the management of topdressing.
[Winter wheat in the middle and lower reaches of the Yangtze River: including the five provinces of Hubei, Hunan, Jiangxi, Zhejiang and Shanghai, southern Henan, Anhui and Jiangsu, south of the Huaihe River. 】
First, the principle of fertilization
(1) Improve the cold, prevent and freeze, promote the transformation of seedlings, and improve the ability of wheat to resist drought and keep cold.
(2) The combination of fertilizer and water management with drought and flood control, pest control and pest control.
Second, fertilization advice
Master the amount and time of irrigation, make comprehensive judgments based on winter frost damage and group conditions, and do a good job in irrigation and fertilizer management.
[Northwest rain-fed winter crops: including northern Hebei Province, northern Beijing, southern Inner Mongolia, Wulanchabu City, most of Shanxi Province, northern Shaanxi Province, western Henan Province, northern Ningxia Hui Autonomous Region, and eastern Gansu Province. 】
First, the principle of fertilization
(1) Improve the ability of wheat to resist drought and cold, prevent cold, freeze, and prevent spring drought.
(2) Early spring topping topdressing and chemical regulation to ensure stable production and increase production of dryland wheat.
Second, fertilization advice
(1) Dry wheat should adopt effective water conservation measures in a timely manner, and at the same time do a good job of reducing soil water evaporation.
(2) Regular fertilization to meet the demand for water and fertilizer in wheat.
[Northwestern irrigated wheat area is dominated by spring wheat, including central Inner Mongolia Autonomous Region, northern Ningxia Hui Autonomous Region, Central and Western Gansu Province, eastern Qinghai Province and Xinjiang Uygur Autonomous Region. 】
First, the principle of fertilization
(1) Reduce nitrogen and phosphorus fertilizers, supplement potassium fertilizer, and supplement micronutrient in moderation.
(2) Fertilization principle: NPK combined with early application of base fertilizer and skillful application of top dressing.
(3) Fertilization should be effectively combined with irrigation.
Second, fertilization advice
(1) Recommended 17-18-10 (N-P2O5-K2O) or similar formula.
(2) The production level is 300-400 kg/mu, and the recommended dosage of formula fertilizer is 20-25 kg/mu. From the start-up period to the jointing stage, the urea is applied 10-25 kg/mu.
(3) The production level is 400-550 kg/mu, and the recommended dosage of formula fertilizer is 30-35 kg/mu. From the start-up period to the jointing stage, the urea is applied 15-20 kg/mu.
(4) The production level is 550 kg/mu or more, and the recommended dosage of formula fertilizer is 35-40 kg/mu. From the start-up period to the jointing stage, combined with irrigation, the urea is applied 15-20 kg/mu.
(5) The production level is below 300 kg/mu, and the recommended dosage of formula fertilizer is 15-20 kg/mu. From the start-up period to the jointing stage, the urea is applied 5-10 kg/mu.
