Description
Technical Field
The invention relates to the technical field of agricultural fertilizers, and relates to a special foliar fertilizer for wheat, in particular to a special foliar fertilizer for wheat, which is suitable for spraying in the jointing stage and the booting stage.
Background
Chemical fertilizers are important agricultural production materials, and are 'grains' of grain crops. For years, chemical fertilizers play irreplaceable roles in promoting food yield increase and agricultural development in China, but the problems of excessive application, blind application and the like of the chemical fertilizers exist at present, particularly the traditional soil fertilization mode seriously damages soil and causes great pollution to the environment. At present, the harm of applying the fertilizer to soil for a long time appears, such as soil hardening, the capability of soil for keeping moisture and nutrients is deteriorated, the utilization rate of the fertilizer is reduced, and the root growth of crops is influenced. The excessive use of the fertilizer increases the agricultural production cost and obviously reduces the income.
The absorption of nutrients by plants is mainly through two pathways, namely roots and leaves. The crops mainly supply nutrition in soil or nutrient solution to plants through root absorption for growth and development. Besides the root system, the crop can also absorb nutrients through stems and leaves (especially leaves). The phenomenon that the non-root system absorbs nutrition during the growth period of crops is the nutrition outside the roots of the crops, and the measure of applying the fertilizer to the surface of the nutrient body except the roots of the crops is called as the fertilizer application outside the roots, namely the so-called foliar fertilizer application. Fertilizers for foliar application are referred to as foliar fertilizers. It is divided into material nutrient foliar fertilizer and functional nutrient foliar fertilizer. The material nutrient foliar fertilizer is a foliar fertilizer for providing trace elements and hormones, and the functional nutrient foliar fertilizer is a foliar fertilizer for providing vital nutrients for crops. The phenomenon that the fertilizer is fixed by soil and is difficult to be absorbed by plants can be avoided by applying certain fertilizers such as phosphorus, iron, manganese, copper, zinc and the like to the leaf surfaces. Compare traditional fertilization mode, the foliar fertilization has following advantage: (1) the fertilizer has quick effect, and the nutrients can be quickly absorbed by the leaves of the crops by the foliar fertilization and directly enter the plants from the leaves to participate in the metabolism of the crops; (2) the fertilizer efficiency is high, the foliar fertilization is not limited by soil conditions and the root system conditions of crops, and the fertilizer efficiency is fully exerted; (3) the cost is low, the fertilizer consumption is less, the cost is low, the application is convenient, and the labor cost is reduced; (4) the soil pollution is reduced, and the damage and pollution to the soil caused by long-term use of the fertilizer are reduced. Due to the advantages of the foliar fertilizer, the market of the foliar fertilizer in China develops rapidly in recent years.
Although the market of the foliar fertilizer develops rapidly, the quality of the products sold in the market is different, and the problems that (1) the specificity of the products is not strong, the application range of various products is wide, but the effects of different crops are different, and the products with good effect and strong specificity aiming at specific crops are lacked; (2) the nutrition is not comprehensive, the variety and the quantity of the nutrients provided by foliar fertilization are limited, and the requirements of all crops cannot be met; (3) the fertilizer efficiency is poor, and particularly, the absorption efficiency of trace elements such as boron, manganese, molybdenum, zinc and the like is not ideal; (4) the adhesion force of the leaves is poor, most of leaf fertilizers are easy to drip from the leaves, the retention time on the surfaces of the leaves is short, and partial nutrient loss is caused; (5) the fertilizer efficiency is short, most of the foliar fertilizers have quick effect but the fertilizer efficiency maintenance time is short.
