Wheat special fertilizer

Abstract

The invention relates to a wheat special fertilizer. The wheat special fertilizer is a compound fertilizer or complex fertilizer containing nitrogen, phosphorus and potassium, wherein the weight ratio of N to P2O5 to K2O is (22-26): (18-20): (4-6). The wheat special fertilizer provided by the invention is reasonable in formula and has complete nutrients, a soil nutrient condition in North Henan is comprehensively considered, proportions of nutrient elements and raw materials of the fertilizer are selected, a ratio of nitrogen to phosphorus to potassium in the fertilizer is reasonable, nutrient releasing rate accords with wheat nutrient demanding rule in a wheat growing region in the North Henan, pertinency is high, operation is convenient, utilization rate of the fertilizer can be improved, application amount of the fertilizer can be reduced (application cost per Mu can be greatly reduced), yield can be increased, and crop quality can be improved; the wheat special fertilizer provided by the invention is applicable to a wheat producing area in North Henan, can be taken as a base fertilizer and can be applied in one step, once fertilizing on one batch of crops can be realized, and labour and time can be saved.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a special fertilizer for wheat suitable for wheat planting areas in northern Henan. Background technique [0002] Wheat is an important food crop in my country. Its sown area and total output rank second only to rice, and it occupies an important position in agricultural production. In recent years, a large number of blind fertilization has caused waste of fertilizers, and the application ratio of nitrogen, phosphorus, and potassium has been seriously out of balance, resulting in the accumulation of soil salt, causing environmental pollution, and excess nutrients in the soil often enter water bodies and The atmosphere not only leads to the decline of fertilizer utilization rate, but also leads to groundwater pollution and eutrophication of rivers and lakes. The cost of agricultural investment has increased, and the benefits of increasing agricultural production have been slow. [0003] According...

AI Technical Summary

Problems solved by technology

However, judging from the development status of my country's agricultural fertilization, there are still the following problems to be solved urgently: First, most of the agricultural fertilizers are still based on general-purpose formulas such as nitrogen-phosphorus-potassium 15-15-15, with the same amount of nitrogen, phosphorus and potassium. It is impossible to apply the same nitrogen, phosphorus and potassium to crops, resulting in a lack of certain nutrients and a waste of certain nutrients

Secondly, farmers fertilize too much nitrogen fertilizer, the crops grow vigorously, the cotton does not sit on peaches, the fruit trees do not bear fruit, the melons and fruits are not sweet, and the crops are seriously lodging, resulting in low yield and poor quality

Third, the amount of fertilizer applied by farmers is too large, and the application of wheat base fertilizer is 50kg per mu or topdressing urea 30kg or ammonium bicarbonate 50kg, resulting in increased agricultural investment costs and serious waste of phosphorus mineral resources

The fertilizers supplied on the market do not take into account the soil's fertilizer supply, fertilizer utilization rate, characteristics of nitrogen, phosphorus and potassium nutrients, and the law of fertilizer requirements of crops. They are often simply based on the amount of nitrogen, phosphorus, and potassium nutrients required for each 100kg of output. , or make general-purpose fertilizers with the same nitrogen, phosphorus, and potassium, such as 16-16-16, which mainly focuses on the total control of nutrients and the proportion of different nutrients, while the fertilizer characteristics of different nutrients, soil nutrient supply characteristics and nutrient absorption of crops Little consideration is given to dynamics, resulting in loss and waste of nutrients

Low crop yield and poor quality
