It is known that the factors that have a great influence on the yield and quality of crops are the planting mode and the soil environment, and the soil environment is the most influential factor among them because it is directly related to the absorption of nutrients and the formation of effective ingredients of crops. In order to improve the yield and quality of polygonum capitatum planting, the method adopted at present is to mix a large amount of base fertilizer into a seedbed and a field to improve the soil environment and the fertility degree of the soil, but the polygonum capitatum growth needs complex elements, the matching difficulty of the base fertilizer is high, the cost is high, and the method is a great obstacle to the improvement of the effect of the base fertilizer.
Along with the growing of polygonum capitatum and the increasing production scale, how to improve the yield and quality of artificially grown polygonum capitatum and solve the problem of treatment of extraction dregs of the polygonum capitatum is considered by practitioners, the amount of the dregs generated by extraction of polygonum capitatum is hundreds of tons every year, the cost for treating the dregs is about 3-4 ten thousand yuan per year, certain economic burden is caused, and the dregs of the dregs are rich in a large amount of organic matters and are used as waste after waste residue treatment. Therefore, the applicant uses the polygonum capitatum dregs as one of raw materials of a polygonum capitatum base fertilizer from the aspect of recycling polygonum capitatum dregs, so as to prepare the special fertilizer for polygonum capitatum, realize the utilization of waste residues and reduce the cost.

The base fertilizer special for planting polygonum capitatum in the step (2) is natural compost, and the composting time is 50-70 days.
The humic acid substances in the step (2) are added into the special base fertilizer for planting polygonum capitatum for 4-5 times in equal parts, the humic acid substances are added for the first time when composting is started, and the humic acid substances are added for the last time when composting is finished.
A method for applying a special base fertilizer for planting polygonum capitatum is characterized in that the base fertilizer is laid in a seedbed or a field when seedling is raised in a greenhouse or field planting is carried out.
According to the fertilizing method of the special base fertilizer for planting polygonum capitatum, the thickness of the base fertilizer is 10-20 cm.
The fertilizing method of the special base fertilizer for planting polygonum capitatum is characterized in that: after the base fertilizer is paved, water is sprayed once every 18-24 hours before seedling culture or field planting, and the base fertilizer is kept moist.
The invention has the advantages of
1. The polygonum capitatum herb residue is used as one of the raw materials of the base fertilizer, so that the herb residue is recycled; in the utilization process, the base fertilizer is subjected to compost fermentation, so that effective elements in the medicine residues are changed into soluble substances, absorption of polygonum capitatum plants is facilitated, the utilization rate of the medicine residues is greatly improved, and the fertilizer efficiency of the base fertilizer is improved;
2. according to the invention, a proper amount of zinc fertilizer is added into the base fertilizer, and the zinc fertilizer is a necessary element formed by components such as total flavonoids in the polygonum capitatum, so that the addition of the zinc fertilizer is matched with polygonum capitatum dregs, the fertilizer efficiency of the base fertilizer is improved, and the growth and quality of the polygonum capitatum are improved;

4. The traditional compost is directly composted by crop stems and excrement, is scattered in a field when in use, and can be uniformly mixed with soil only by continuously turning over soil.
5. The polygonum capitatum is extracted by ethanol generally, the polygonum capitatum extraction dregs are pretreated before compost fermentation, after residual ethanol is volatilized completely, the compost fermentation is carried out in a water supplementing mode, not only can the normal compost fermentation of the dregs be not influenced, but also the accumulation of ethanol in the fermentation engineering can be avoided, and the damage to enzymes in soil is reduced, so that the polygonum capitatum plant can grow normally, and in addition, the nutrient components contained in organic matters in the polygonum capitatum are beneficial to the growth of the polygonum capitatum plant and the accumulation of effective components, so that the yield and the quality of the polygonum capitatum planted by the method are improved.
To further illustrate the effects of the present invention, the applicant made the following experiments:
experimental example 1: the yield of the polygonum capitatum planted by using the traditional polygonum capitatum planting base fertilizer and the base fertilizer which uses polygonum capitatum dregs as the base fertilizer but is not treated according to the method is compared with the yield of the polygonum capitatum planted by using the special base fertilizer for polygonum capitatum of the invention
1, base fertilizer: the traditional base fertilizer for planting polygonum capitatum consists of 10-20 parts of dry chicken manure, 40-50 parts of dry cow manure and 5-10 parts of calcium superphosphate.
And 2, base fertilizer: the base fertilizer which uses polygonum capitatum dregs as base fertilizer but is not processed according to the method of the invention is composed of 120 parts of polygonum capitatum extraction waste residues, 450 parts of fine soil, 200 parts of sawdust, 55 parts of zinc fertilizer and 70 parts of humic acid substances, and the raw materials are mixed according to a certain proportion and then directly paved in seedbeds and fields without being processed according to the method of the invention.
And 3, base fertilizer: the base fertilizer of embodiment 3 of the invention.
Respectively spreading the base fertilizers in the 3 parts of the field and the 3 seedbeds with the same area and adjacent geographic positions, planting according to a traditional planting method, harvesting polygonum capitatum after the planting, preparing dry products by adopting the same process, weighing the dry products, and obtaining the results shown in table 1.

Figure BDA0002424818110000051
Through comparison, the per mu yield of the polygonum capitatum planted by the base fertilizer is obviously improved. However, the applicant finds that the base fertilizer of the invention has improved yield after being used, but the yield is lower than that of the new planting method of our company, and the applicant considers that the base fertilizer can be caused by the planting method. But the yield is still obviously improved only from the influence of the base fertilizer on the yield of the polygonum capitatum.
Experimental example 2: dynamics research of prepared base fertilizer on enzymatic reaction of invertase in soil during pretreatment and non-treatment of polygonum capitatum extraction residues
And (2) equally dividing the alcohol-extracted polygonum capitatum extraction medicine residues into 2 groups, wherein 1 group is treated according to the method, 2 groups are directly mixed with the formula of the base fertilizer and subjected to composting treatment, after the treatment is carried out for a specified time, the groups are respectively mixed with equal mass and quantity of soil samples, then the enzymatic reaction of invertase in the soil samples is analyzed, and the results are shown in table 2.
