Description
Technical field:
The present invention relates to agricultural fertilizer field, particularly relate to a kind of preparation method of biological organic fertilizer, be specially a kind of preparation method that can improve the biological organic fertilizer of potato commodity potato rate.
Background technology:
Potato (SolanumtuberosumL.) has another name called potato, potato, potato etc., belongs to the annual herb plant of Solanaceae Solanum potato group.During the 17th century, potato imports China into.Yam starch content is high, can reach the 60%-80% of dry-matter, so a lot of area is regarded food crop to treat; Potato VITAMIN and rich in protein, a lot of area is regarded vegetables and is treated.Potato is food crop, is again vegetable crop, so more and more pay attention to the plantation of potato.
Along with development and the growth in the living standard of potato processing industry, the quality requirements of people to Potato Cultivars is more and more higher.The quality of potato is mainly determined jointly by its exterior quality and interior quality, exterior quality refers to potato shape, size, color, the eye depth, wastage rate of peeling, potato skin antibody Monoclonal ability, and interior quality refers to dry matter content, protein content, starch content, vitamin contents, reducing sugar content and whether is applicable to industrial processes needs etc.
The quality requirements of potato is different because purposes is different, if edible and fresh potato outlet, requires: stem tuber is oval for fresh potato, Calusena lansium or red Beijing opera meat, epidermis is smooth, dry-matter is containing 15%-17%, and crude protein content 2% is with, the fresh potato of Vc content 25mg/100g, stir-fry and eat, steamed wheaten foods local flavor, mouthfeel be good, shelf-stable; If for fried processing, require: stem tuber is circular, white skin plain boiled pork, and eye is shallow, commodity potato rate more than 85%, reducing sugar content is lower than 0.25%, and low temperature resistant storage, between proportion 1.085-1.100, explodes eating habit taste, mouthfeel is good; If do full powder, starch processing, require: starch content must more than 15%, reducing sugar content is lower than 0.25%, and low temperature resistant storage, proportion is more than 1.085, and food flavor after product rehydration, mouthfeel are good.
Commodity potato rate is the important indicator weighing potato planting benefit, and improving potato commodity potato rate is also improve potato planting benefit.Different planting patternss can change the commodity potato rate of potato; Apply the commodity potato rate that inorganic and compoiste fertilizer also can improve potato; The density of commodity potato rate marine site plantation is simultaneously relevant.Generally can effectively improve commodity potato rate by above-mentioned three kinds of modes reaches more than 87%, but well can't improve the commodity potato rate of potato.
It is a kind of seed potato simple storage method that Chinese invention patent CN101258805 discloses, the seed potato simple storage method of this invention compared with prior art has following positively effect: solve peasant household for a long time and store mixed to commodity potato (needing secretly to preserve) and potato seed (scattered light is stored), changing peasant household, existing bud is long excessively weak because of one time, need prior to seeding to erase, cause affecting productivity effect, the bud that potato seed is sent is short and sturdy, reach desirable potato seed physiological age and germination state, grow at field normal growth, improve output more than 15%, commodity potato rate increases by more than 12%.This invention is simple, can improve commodity potato rate more than 12%, still well can not reach the technique effect of commodity potato rate 95%.
Chinese invention patent CN102282993A provides the cultivating method of overlay film after a kind of potato set, 20-November 20 October is sowed, seedling grows to 15 centimetres, the rear covering with plastic film of ridging of topdressing, improve the output capacity in soil, cooperation " 88 " per mu yield can reach 2861 kilograms, and No. 6 per mu yields of beautiful potato can reach 3624 kilograms, increase more than 300 kilogram than the potato per mu yield of general planting, per mu yield value increases 1400 yuan; Due to covering with plastic film, can reach the effect of insulation preserve moisture and fertility, promote the equilibrium supply of potato production, improve the commodity rate of potato, commodity rate reaches 94%, improves more than 10% than the potato commodity rate of general planting; The problems such as it is low that this invention efficiently solves potato per mu yield, and commodity rate is low, but the method improves economy and the human input of plantation by the mode of overlay film.
Summary of the invention:
The present invention is directed to prior art Problems existing, a kind of preparation method that can improve the biological organic fertilizer of potato commodity potato rate is provided, by using the biological organic fertilizer that this preparation method prepares, the commodity potato rate of potato reaches more than 95%, improve the economic benefit of plantation, improve Soil structure simultaneously, improve plantation ecological benefits, there is great promotional value.
The invention provides following technical scheme:
A preparation method for the biological organic fertilizer of potato commodity potato rate can be improved, comprise the following steps:
The first step: add photosynthetic bacteria, sporotrichum thermophile bacterium and thermophilic actinomycete and prepare chicken manure fermenting material;
