Description
Technical Field
The invention relates to a nutrition-adjusting foliar fertilizer special for cotton, and belongs to the technical field of cotton planting.
Background
The compound sodium nitrophenolate is a strong cell activator, can quickly permeate into a plant body after contacting with the plant, promotes the protoplasm flow of the cell, and improves the cell activity. The compound sodium nitrophenolate is the only artificially synthesized plant growth regulator approved by the United states environmental protection agency in 1997 and entering the United states green food engineering, has no residue problem, can be used in the whole life period of plants, can be used for the treatment of seed soaking, seed dressing, seedbed perfusion, leaf surface spraying, root soaking, stem coating, fruit surface spraying and the like, can be used from seeding to harvesting, and has very remarkable use effect. The dosage of the original medicine of a plurality of plant growth regulators is generally a few horns per mu or even more than 1 yuan, and the dosage of the compound sodium nitrophenolate per mu is only a few cents, which can bring the benefit to farmers. The compound sodium nitrophenolate has magical effect, only a little of fertilizer, pesticide, herbicide and feed are needed to be added, the fertilizer efficiency, the pesticide effect and the weeding effect can be improved, the antagonism can be removed, and the safety coefficient to crops is high.
At present, part of the existing formula of the special foliar fertilizer for cotton is mainly adjusted, and the nutritional growth and reproductive growth of cotton are adjusted by adding one or more exogenous hormones, such as auxin, gibberellin, cytokinin, brassin and the like, so that the price is higher; in addition, part of the formula is mainly nutrient, and the nutrient is promoted to be efficiently absorbed by the cotton leaves by adding major elements of nitrogen, phosphorus and potassium, trace elements of boron, zinc and the like and other chelating agents. The two formulas are different in autumn, the adjusting formula can coordinate the vegetative growth and reproductive growth of cotton, but the using amount of the adjusting formula in different growth periods cannot be accurately quantified, and the side effect can be generated on the contrary if the using amount is not well controlled, and the nutritional condition of the cotton can be rapidly improved if the nutritional foliar fertilizer is applied to the foliage of the cotton, but the vigorous growth of the cotton can be caused if the using amount is too large, the reproductive growth of the cotton can be relatively inhibited, and the yield increasing effect cannot be achieved.
Strong section and the like (2011) report that the spraying of a 1.8% compound sodium nitrophenolate aqueous agent for 2 times in the cotton bud period has the effect of increasing the yield of cotton and has no adverse effect on the quality of cotton fibers. But the problem exists in that the dosage of the compound sodium nitrophenolate is too low to influence the accuracy of the dosage; and the yield increasing effect is not very ideal.
