Description
Technical Field
The invention relates to the field of plant fertilizer formulas, in particular to a special foliar fertilizer for fiber-type industrial large hemp.
Background
Industrial Cannabis sativa (Cannabis sativa L.) refers to a variety of Cannabis sativa having a Tetrahydrocannabinol (THC) content of less than 0.3%, and is an annual herb plant of the Cannabis genus (Cannabis) of the Cannabinaceae family (Cannabinaceae). At the beginning of the establishment of new china, research on cannabis has mainly focused on high-yield cultivation experience. In recent years, in order to promote the development of industrial hemp industry, breeding experts breed a plurality of special industrial hemp varieties according to the uses such as fiber type, seed type and the like, such as: the hemp I, the golden knife 15, the Yunxian No. 1-3, the Qingma No. 1, the Fenma No. 3 and the like.
With the adjustment of the planting structure, the planting area of industrial hemp in China is larger and larger, and the industrial hemp is gradually an important economic crop. In the planting process of industrial hemp, chemical fertilizers are generally adopted to promote the production of the industrial hemp, and the crop yield and the fiber quality can be improved to a certain extent. Since industrial hemp is a flat-sown crop, the fertilizer is generally applied in one application as a base fertilizer. With the growth of industrial hemp, a phenomenon of fertilizer loss may occur at a later stage, which affects the yield of industrial hemp. In order to prevent the phenomenon, a new cultivation technology must be matched to better improve the production yield of the industrial hemp.
The fertilizer is a foliar fertilizer which directly sprays nutrients needed by crops on the foliar surface. The leaf fertilizer is absorbed by the leaves, and the air holes on the surface of the leaves are the channels for the leaf fertilizer to enter the leaves and exert the functions of the leaf fertilizer through the absorption of the leaves. The foliar fertilizer is used as an additional fertilizer mode, can be adjusted and sprayed according to weather conditions and actual growth conditions of crops, and is more convenient to use.
The urea substances in the fertilizer have softening effect on the cuticle of epidermal cells of crop leaves and can accelerate the permeation of other nutrient substances, so that the urea becomes an important component of the foliar fertilizer. However, in actual spraying, the foliar fertilizer is easy to drip from the leaf surface or be leached by rainwater, which causes great waste.
