Abstract

The invention discloses a preparation method of a series organic fertilizer for reducing the empty rate of Chinese chestnuts. Poultry excrement and wormcast are used as main materials, and a certain quantity of nitrogen, phosphorus, potassium, zinc and boron nutrients are coordinated with the main material to prepare the special fertilizer for Chinese chestnuts. The fertilizer is capable of obviously reducing the empty rate of Chinese chestnuts and the spider mite infection rate of chestnut trees and promoting the root development of chestnut trees. According to the nutrient demands of Chinese chestnuts in different growth periods, the catering type series special fertilizer for Chinese chestnuts is formed, the problem of unscientific fertilization of Chinese chestnuts is solved, and the problems that unscientifically treated poultry excrement is capable of polluting the environment and nutrient sources are wasted are synchronously solved. Compared with conventional fertilization, the application of the series special organic fertilizer for Chinese chestnuts enables the empty rate of Chinese chestnuts to be reduced by more than 60% and the yield of Chinese chestnuts to be increased by more than 30%, and can achieve the remarkable synergism.

Description

A kind of preparation method reducing the organic fertilizer of Empty Fruit of Chinese Chestnut rate
Technical field
The present invention relates to a kind of organic fertilizer improving the dry fruit such as Chinese chestnut, walnut yield and quality, particularly a kind of preparation method reducing the organic fertilizer of Empty Fruit of Chinese Chestnut rate.
Background technology
The land occupation condition that high-quality Chinese chestnut produces is Hills And Low Mountains, Chinese chestnut is best in quality in Jingdone district, this regional soil matrix mostly is the comparatively loose parent rock such as leaf gneiss, grouan, soil mostly is gravel matter leaching dynamics, soil physical and chemical property is loosing soil but gravel concentration is high, permeability is good but soil fertility is low, and especially the soil organism is low, causes that soil supplying nutrient capability is low, water-retention fertilizer is poor.For a long time traditional Chinese chestnut produce in the extensive management of clay fertilizer water, along with introducing a fine variety and planting culture technology popularization application of new variety in recent years, highlight the subject matter that Empty Fruit of Chinese Chestnut becomes restriction Chinese chestnut output at present, therefore the technical problem that applies fertilizers scientifically of High Yield for Chinese Chestnut high-quality urgently to be resolved hurrily, production more needs the Chinese chestnut technology of applying fertilizers scientifically is turned materially serial pantry formula Chinese chestnut special fertilizer.For this reason, find a kind of Chinese chestnut organic fertilizer special that there is reduction Empty Fruit of Chinese Chestnut rate, meet High Yield for Chinese Chestnut high-quality nutrient demand,, water-retention fertilizer low with the soil fertility progressively improving Chestnut Orchard, reduce or avoid the problems such as Empty Fruit of Chinese Chestnut, this has significant economic implications to Chinese chestnut good quality and high output.
Summary of the invention
The object of the present invention is to provide a kind of preparation method reducing the organic fertilizer of Empty Fruit of Chinese Chestnut rate.
The object of the present invention is achieved like this.Utilize the materials such as cow dung, wormcast, brown coal (humic acid), coordinate a certain amount of big or middle, micronutrient element, prepare a kind of Chinese chestnut organic fertilizer special with the significantly empty fluffy rate of reduction Chinese chestnut tree, red spider susceptible gene, raising Chestnut Orchard soil fertility and water-retention fertilizer.
Concrete, the preparation method of the organic fertilizer of reduction Empty Fruit of Chinese Chestnut rate of the present invention, comprises the following steps:
(1) cattle manure
The fresh cow dung cleared out in cattle farm is dried in the air water content 65% ~ 75%, according to 0.1% ~ 0.7% inoculation enzymatic microorganism of mixture fresh weight, one deck cow dung one deck bacterium powder, builds heap fermentation, starts to turn over buttress when there is mycelia in stacking after mixing, control heap body core temperature and be no more than 65 DEG C, general summer, 2 ~ 3d turned over once, spring and autumn 4 ~ 10d once, the time of compost fermentation is fixed with temperature, control at 10 ~ 45d, north of china in winter need cover the insulation of the thing such as black plastic or corn stalk.The decomposed cow dung organic content obtained is generally at 30% ~ 37.5%, N+P 2o 5+ K 2the total amount of O is 3% ~ 4%;
(2) wormcast is prepared
With decomposed cow dung feed earthworm produce wormcast, bank up ground point selection tree in the ranks or ground, cool place (avoiding direct sunlight), decomposed cow dung heap slivering buttress, advise high × upper wide: the bar buttress (just to carry earthworm and to feed in raw material) of lower wide (cm)=60 ~ 100 × 80 ~ 100:100 ~ 150 cm, 0.1 ~ 0.5kg earthworm (Eisenia foetida) is inoculated by the long 100cm of buttress, in buttress, temperature controls 20 ~ 25 DEG C (temperature ranges 5 ~ 30 DEG C), treat that cow dung becomes small-particle state, when color becomes brownish black by brown, cow dung changes into wormcast substantially, earthworm is separated with wormcast.General cow dung earthworm of feeding is converted into the time 30 ~ 45d of wormcast, and the north needs covered plastic cloth or maize straw insulation after mid-November, in buttress, temperature is lower than earthworm hibernation when 5 DEG C, and Second Year temperature in spring comes into play after ging up.The wormcast organic content 30% ~ 37.5%, N, P obtained 2o 5, K 2the total amount of O is 3% ~ 4%;
(3) mix
By step (1) gained decomposed cow dung, step (2) gained wormcast moisture is cool to 25% ~ 35% respectively, by decomposed cow dung, wormcast, brown coal are by following mass ratio mixing, cow dung: wormcast: brown coal=(0.8 ~ 1.2): (0.8 ~ 1.2): (0.3 ~ 0.6), obtain mixing organic materials, then organic materials and N P and K zinc boron mixed fertilizer will be mixed in mass ratio (8 ~ 9.5): (0.5 ~ 1.5) mixes, wherein, urea is added in finished product organic fertilizer per ton, diammonium phosphate, each 10 ~ 20 kg of potassium sulfate, zinc sulfate 5 ~ 10 kg, borax 2 ~ 6 kg, thus be reduced the organic fertilizer of Empty Fruit of Chinese Chestnut rate.
Gained finished product organic fertilizer reaches the organic fertilizer quality standard of NY_525-2012, organic content>=45% in organic fertilizer, N+P 2o 5+ K 2o total amount>=5.0%, pH about 7.5, moisture content≤30%.
The beneficial effect that the present invention obtains is as follows: the present invention, according to Chinese chestnut uptake characters, Chestnut Orchard soil supplying nutrient capability and the quantitative effect of N P and K zinc boron on Chinese chestnut, prepares series " pantry formula " Chinese chestnut organic fertilizer special.Both solved during current Chinese chestnut produces the problem that do not apply fertilizers scientifically, solve feces of livestock and poultry not scientific disposal, contaminate environment also wastes the problems such as nutrients resource simultaneously.Compare with habits fertilization, use serial Chinese chestnut organic fertilizer special of the present invention, Empty Fruit of Chinese Chestnut rate reduces by more than 60%, and Chinese chestnut output increases by more than 30%, and cost-saving synergistic is remarkable.
Embodiment
Following examples are for illustration of the present invention.
