Description
Technical Field
The invention relates to the technical field of foliar fertilizers, and particularly relates to a foliar fertilizer special for corn and a preparation method thereof.
Background
Corn is the third crop in China, and the perennial planting area is 3000 ten thousand hm2About, it accounts for more than 30% of the total grain production in China. The whole growth period of the corn is subjected to a seedling emergence period, a trefoil period, an elongation period, a large flare period, a heading period, a flowering period and a mature period. The nutrient requirement of the corn in the whole growth period is that nitrogen is maximumThe potassium is the third place, and the phosphorus is the third place. Generally, every 100 kg of grains need to absorb 2.5 kg of nitrogen (N), 0.5 kg of phosphorus (P) and 1.7 kg of potassium (K) from soil. In addition, the corn is sensitive to zinc, the zinc influences the synthesis of endogenous auxin such as indoleacetic acid in corn plants, the iron influences the content of chlorophyll in leaf surfaces, the corn is a moderate boron-resistant crop, and the demand for manganese and molybdenum elements is low. The foliar fertilizer is a fertilizer type in which nutrient elements are applied to the surfaces of crop leaves and the basic functions are exerted through the absorption of the leaves, so that under the condition of reasonably applying a base fertilizer, the proportion among major elements, secondary elements and trace elements can be effectively balanced by spraying the special foliar fertilizer for the corn in each key period of the corn, and the special foliar fertilizer plays a key role in promoting the normal and rapid growth of plants and increasing the yield and improving the quality. The existing foliar fertilizers mostly adopt different types of amino acids and a large amount of functional chemical fertilizers, but the produced corn foliar fertilizers have high cost, large fertilizer demand and high investment, but the yield and the quality are still not high and are not environment-friendly.
The CN109400275A patent discloses a novel corn leaf fertilizer and a preparation method thereof, which adopts raw materials of potassium oxalate, sodium nitrate, trichloroisocyanuric acid, serine, histidine, methionine, salicylic acid, malic acid and cellulose triacetate, directly mixes and stirs the raw materials, and uses after dilution, thereby improving the corn yield, reducing the soil damage, mainly using the salicylic acid to improve the utilization rate, but the utilization rate of the fertilizer still needs to be improved, and the cost is higher.
The CN110483157A patent discloses a corn foliar fertilizer which comprises boric acid, potassium carbonate, epsilon-polylysine, humic acid, methylene succinic acid, trace elements, diethyl aminoethyl hexanoate and a chelating agent.
The CN105439693A patent discloses an lodging-resistant disease-resistant growth-promoting corn foliar fertilizer, which comprises the following components: the fertilizer is added with potassium, calcium, zinc, silicon and other elements, has high nutrient utilization rate and sterilization effect, prevents various maize bacterial wilt, large leaf spot and small leaf spot diseases and the like, but has high cost and low yield and still cannot solve the problems.
