The invention can effectively control the crops vigorously, has positive effects on reproductive growth, green synthesis of leaves and photosynthesis of the crops, can obviously improve the photosynthesis of the crops after being compared with paclobutrazol and phosphorus-potassium liquid fertilizers in the prior art, thereby achieving the purpose of increasing the yield.
Description
Technical Field
The invention relates to the technical field of fertilizer preparation, in particular to a preparation method and an application method of a vigorous-growth-controlling fertilizer.
Background
In the planting process of crops, the contradiction between vegetative growth and reproductive growth and the growth of overground parts and underground parts can be met. The harm caused by the vigorous growth of crops in the actual production process is very huge. Vegetables in a vigorous growth period, such as vegetables in a flowering and fruit setting period, have the phenomena of little fruit setting, slow fruit swelling or flower and fruit dropping. The main reasons for the above phenomena are unbalanced vegetative growth and reproductive growth, over-vigorous vegetative growth, suppressed reproductive growth, organic nutrition which is transported to branches and leaves but not to flowers and fruits, thereby causing poor flower bud differentiation and fruit setting. Even if the fruit is set, the fruit tends to be misshapen, or even not swelled. And the reproductive growth is over-vigorous, and the plants consume excessive nutrients, which can cause premature senility of the vegetables. After the fruit trees enter the reproductive growth period, if the vegetative growth is too vigorous, the fruit setting is less, the fruit swelling is slow, and finally, the yield is low, the quality is poor and the income is influenced.
The current vigorous growth control products on the market are basically plant growth regulators, mainly comprise chlormequat chloride, paclobutrazol and mepiquat chloride, act as antagonists of gibberellin synthetic substances, belong to growth retardants, weaken the growth vigor of crops and do not influence cell division. But the existing regulator has obvious defect of vigorous control, firstly, the use safety technical requirement is higher, and the pesticide damage is easy to occur when the concentration is not suitable for use; secondly, the residual time of partial components is long, which has influence on the next crop; thirdly, the use of the regulator product is easy to cause premature senility of crops and influence the yield and the quality.
