Description
[technical field]
The invention belongs to agricultural technology field, for the phytology characteristic of potato uniqueness, be intended to prepare a kind of potato special use, that be rich in xanthohumic acid, the high-efficient liquid fertilizer of Different Nutrient Elements can be provided at the different growth phases of potato.
[background technology]
China Shi Yige large agricultural country, agricultural is the basis of national economy, in agriculture evolution, grain-production is agriculture center all the time.Potato not only has higher nutritive value, also has medicinal health value; And potato is drought-enduring because having, cold-resistant, the feature of wide adaptability, the soil of national most area and weather condition all can meet its working condition, have become and have been only second to wheat at present, paddy rice, and the fourth-largest crop of corn.Therefore, research potato special fertilizer material, the output and the quality that improve potato have very important effect for the Food Security that solves China.
Liquid is to preserve various bioactive top conditions, and a lot of makeup, cleaning product are that liquid state is exactly this reason.First the complete processing of liquid fertilizer is carried out at low temperatures, does not break the activity of organic molecule in fertilizer; Secondly in liquid fertilizer, the various active factor can also be added, the absorption of root system to nutrient can be promoted; Again, liquid fertilizer nutrient exists and can directly be diffused into root system surface with solution state, thereby has greatly improved fertilizer utilization efficiency.
In order to guarantee the stable existence of Liquid Fertilizer, prevent that metal ion from separating out with precipitation forms, in the production process of Liquid Fertilizer, to add some organic sequestering agents, metal ion is existed with stable inner complex form.So not only can improve the stability of Liquid Fertilizer, more be conducive to the absorption of crop to liquid fertilizer, improve fertilizer utilization efficiency.Xanthohumic acid, because containing the natural radioactivity chelation groups such as a large amount of carboxyls, hydroxyl in molecule, enjoys favor in the application of Liquid Fertilizer.
[summary of the invention]
The object of the invention is to overcome the feature that current Liquid Fertilizer nutrient is single, system is unstable, fertilizer efficiency is poor, a kind of preparation method who is rich in the potato special efficient liquid composite fertilizer of xanthohumic acid and various nutrient elements is provided.
The invention provides a kind of xanthohumic acid composite efficient liquid fertilizer formula that is rich in, it is characterized in that, composed of the following components by weight:
