Problems solved by technology

[0003] At present, in terms of konjac disease prevention and control and fertilizer application, more emphasis is placed on the application of chemical agents to prevent and control plant diseases and insect pests in the middle and late stages of konjac growth and fertilizer application techniques. Although these measures have played a greater role in konjac production, but , there are also some insurmountable difficulties and problems
First of all, the usual comprehensive prevention and control methods for konjac are relatively complicated and cumbersome, with many operating links and a large amount of labor, and it is not easy to master them well. master
Secondly, the new technology of konjac cultivation is relatively slow in the current rural conditions. The main reason is that konjac has a long growth cycle, and every link is very important. Any mistake in any link will cause immeasurable losses.
Generally, farmers tend to remember the training techniques of the current season, but they are easy to forget later ones, so they operate according to the usual crop planting habits; in addition, local governments pay different attention to konjac technology, and there is less technical training; the third is the konjac cultivation. The awareness of soil disinfection and prevention is not strong. I don’t know that the main diseases of konjac are soil-borne diseases. Generally, it is only after the above-ground plants of konjac are infected that they think of using pesticides to control them. Little do they know that many diseases come from the ground, and the result is that the control effect on the infected plants It is poor or even irreparable; the fourth is that the fertilization is not standardized, and the characteristics of the fertilizer required for the growth of konjac are not well understood. Causes plant damage and disease, which brings unnecessary losses; five konjac crops are common, because konjac has good economic benefits and limited planting land in mountainous areas, effective crop rotation cannot be carried out, and konjac is planted on the same piece of land every year, or limited by conditions Or lack of basic knowledge and ignorance of technology and neglect of soil disinfection treatment, causing konjac diseases to become more and more serious, and finally causing greater losses

Embodiment 1

[0019] A special medicinal fertilizer for konjac is characterized in that: it is composed of 15-27% base material and 73-85% medicinal fertilizer in mass percentage;

[0020] 1. Preparation of special medicinal fertilizer for konjac: take 16.3 parts of urea, 22.7 parts of monoammonium phosphate, 35 parts of potassium sulfate, 0.1 part of nitrofulvic acid, 0.08 part of agricultural streptomycin sulfate, 0.12 part of chlorothalonil, 25.7 parts of clay After mixing and pulverizing, put it into the mixer and stir for 5min-10min, then put it into the drum granulator for granulation, and then send the agglomerated material to the rotary dry granulator, granulate, heat sieve, cool, dry, Sieve, seal and pack to get the special medicinal fertilizer for konjac.

[0021] 2. Take the above-mentioned special medicinal fertilizer for konjac, and apply 50 kg per 666.7 square meters as base fertilizer (base fertilizer) for field test. The test konjac varieties are all konjac flowers (the same...

Embodiment 2

[0027] 1. Preparation of special medicinal fertilizer for konjac: take 21 parts of urea, 22 parts of monoammonium phosphate, 36 parts of potassium sulfate, 0.08 part of nitrofulvic acid, 0.07 part of agricultural streptomycin sulfate, 0.1 part of chlorothalonil, 20.75 parts of clay parts, and the subsequent preparation method is the same as that in Example 1.

[0028] 2. Take the above-mentioned special medicinal fertilizer for konjac, and apply 60 kg per 666.7 square meters as base fertilizer (base fertilizer) for field test. The test konjac varieties are all konjac flowers.

[0029] The field test methods and results are as follows:

[0030] 1) Test method: Dig a 10-15cm deep ditch after completing the field, put the konjac seeds into the ditch as required, then cover the konjac seeds with fully decomposed farmyard manure, and then apply special fertilizer or compound fertilizer Spread on the farmyard manure, and finally cover the soil to form a ridge. The amount of farmya...

Embodiment 3

[0034] 1. Preparation method of special medicinal fertilizer for konjac: take 17.9 parts of urea, 25 parts of monoammonium phosphate, 34 parts of potassium sulfate, 0.1 part of nitrofulvic acid, 0.06 part of agricultural streptomycin sulfate, 0.11 part of chlorothalonil, clay 22.83 parts, and the subsequent preparation method is the same as that in Example 1.

[0035] 2. Take 70 kg of the above-mentioned special medicinal fertilizer for konjac as base fertilizer (base fertilizer) for field experiment.

[0036] The field test methods and results are as follows:

[0037] 1) Test method: first dig a 12cm-15cm deep trench after the whole field, and then apply farmyard manure at the bottom of the trench, then apply special fertilizer or compound fertilizer on the surface of farmyard manure, then cover with 3cm thick soil, and put taro (The main bud is inclined upward, the same below), and finally cover the soil to raise a ridge. The amount of farmyard manure applied is about 2000...

Abstract

The invention discloses a special medicine fertilizer for konjak. The special medicine fertilizer is characterized by being formed by the following components in mass percentage: 15-27% of a base material and 73-85% of a medicine fertilizer. The medicine fertilizer is formed by the following raw materials in parts by weight: 16-21 parts of urea, 22-28 parts of monoammonium phosphate, 34-36 parts of potassium sulfate, 0.08-0.1 part of nitryl fulvic acid salt, 0.06-0.08 part of agricultural streptomycin sulfate and 0.1-0.12 part of chlorothalonil. When the special medicine fertilizer is used, 50-80kg of the medicine fertilizer is applied to each 666.7 m<2>. The medicine fertilizer disclosed by the invention can improve the anti-disease capability of a konjak plant and prevents main konjak disease bacteria from invading konjak plants and corms; the medicine fertilizer ensures the sufficient requirements of the growth of the konjak on the a main fertilizer; and the medicine and the fertilizer are combined so that the special medicine fertilizer prevents diseases, balances nutrition, improves the soil, improves the medicine fertilizer effects, enhances the konjak resistance, accelerates the growth of the konjak and has the very obvious social, economic and ecological comprehensive benefits.
