Technical field
The present invention relates to agricultural fertilizer technical fields, and in particular to a kind of shallot field planting fertilizer suitable for Shajiang black soil and its
Fertilizing method.
Background technique
Shajiang black soil is one of big mid and low yield soils type of China's Huang-Huai-Hai plain three, and national total area is up to 60,000,000
Mu is distributed mainly on the province such as Anhui, Henan, Shandong and Jiangsu.Anhui Province's Shajiang black soil area is maximum, up to more than 2,400 ten thousand mu, accounts for
The 41.5% of the national Shajiang black soil gross area.Shajiang black soil is also the maximum middle low yield soil types of Anhui Province's area, according to statistics,
Shajiang black soil accounts for the 41.2% of the whole province's cultivated area, accounts for the 67.8% of the Anhui Province nonirrigated farmland gross area, accounts for Northern Area of Huaihe River cultivated area
70%.The Shajiang black soil content of organic matter is low, and nutrient is barren, and nitrogen stress lacks phosphorus, and microelement validity is low in sulphur, zinc, manganese etc..
Shallot is Liliaceae allium, originates in the Central Asia and western China, and in China, cultivation history is long, cultivates model
It encloses extensively, it is especially the most universal with Basin of Huaihe River, the Central Plains to the north of the Qinling Mountains and northern area, early have become the perfume (or spice) of anniversary stable market supply
Pungent leaf vegetables special vegetable.The most apparent feature of shallot is exactly containing volatile oil, and main ingredient is allicin and fitoncidin, has spy
Different fragranced and pungent is one of most common flavouring in people's daily life, is widely used in the flavoring of the cooking and food,
It earns foreign exchange vegetables for the important specialty in China.According to statistics, about 8,100,000 mu of the annual shallot cultivated area in China, nearly 60,000 t of export volume, phase
90% or so of world's shallot cultivated area and export trade amount should be accounted for, occupies particularly important status in the world.
Anhui is the important producing region of national shallot, and there are plantation in various regions, and more than 20 ten thousand mu of the long-term cultivated area of the whole province is main to concentrate
In the Huaibei.The foremost shallot place of production of the whole province is Soil Development in Huaibei Plain Linquan County, and the shallot of this county plantation, yield is high, and quality is good, growth
Phase is short, good in economic efficiency, and the long-term cultivated area in the whole county is more than 100,000 mu, and product sells to main big and medium-sized cities in all parts of the country, over the ground
Square expanding economy plays important facilitation, is the producing region that Anhui Province shallot is concentrated the most.
Shallot is a kind of high yield vegetables, and yield is high, and per mu yield while being fertilizer favorite work again up to 5000kg or more when high-yield culturing
Object, growth and development need to absorb a large amount of nutrients.It was found that shallot absorbs, potassium is most, nitrogen takes second place, phosphorus is minimum, sulphur is liked, to potassium nitrogen
Nutrition is very sensitive.Anhui Province shallot main producing region-Soil Development in Huaibei Plain soil types is mainly Shajiang black soil, is a kind of middle low yield class
Type soil.Since shallot place of production peasant culture quality is not high, the consciousness of applying fertilizers scientifically is not strong, also lacks shallot nutrient fertilization technology,
Lack corresponding shallot formula fertilizer, causes the fertilising of green onion agriculture blindness, excessive fertilization and the single nitrogenous fertilizer of application etc. are unreasonable to apply
Fertile phenomenon is prominent, and potassium investment is less than output, the decline of Soil Available potassium content, nitrogen phosphoris and potassium fertilizer ratio numerous imbalances, middle amount and micro member
Element lacks, and leads to shallot nutrient imbalance, pest and disease damage aggravation, and the harmful substance contents such as NO3-N and NO2-N increase, nutriment
Qualitative change is poor, and yield reduces sharply, and applies fertilizer low in economic efficiency with plantation shallot, and Higher output is not accompanied by a higher income, affects the positive of green onion agriculture production
