Description
Technical field
The invention belongs to technical field of fertilizers, and in particular to a kind of potato special fertilizer and preparation method thereof.
Background technology
Potato, also known as potato, potato, foreign sweet potato etc., belongs to Solanaceae herbaceos perennial, and stem tuber can be edible, is complete
The fourth-largest important cereal crops of ball, are only second to wheat, paddy and corn.Potato has wide adaptability, stable high yield, nutrition
Various advantages such as comprehensive, propulsion staple food products and industry development prospect are very wide, will provide more guarantors to Food Security in China
Barrier.
Ministry of Agriculture's data display, potatoes cultivated area in 2014 is up to 5,570,000 hectares, fresh tuber yield more than 9,500 ten thousand
The a quarter in ton, cultivated area and the yield Jun Zhan worlds or so.Although potatoes yield is big, per unit area yield is relatively low, only
1.2 tons every mu, only the 80% of world average level, less than the 1/3 of the developed country such as Holland, Britain, France, U.S. level, with
Domestic every mu more than 5 tons high yield typical case compares, also very big growth space.
Increase along with population, urbanization such as quickly propels at the factor, the grain demand of China continues to increase, grain supply and demand shape
Gesture allows of no optimist, as the potato of the fourth-largest cereal crops, its plantation prospect just becomes boundless.But at present not
Rational fertilising custom but limits the raising of potato yield and quality, not only causes the waste of fertilizer, also gives soil band
Many problems are carried out.At present, the yield potential of China potato does not give full play to also, as long as potato fertilization technical elements are slightly
Plus improve, the yield potential of potato is releasable.
Potato breeding time fertilizer requirement is larger, is typically to like potassium crop, and the demand percentage for nitrogen, phosphorus, potassium is about 2:
1:4, potato is also larger for the demand of manganese, boron, zinc in addition.With the growth of potato, its demand for nutrient
Gradually increase, the knot potato phase is that potato absorbs nutrient most period.Existing fertilizer can not be special according to the need of potato growth fertilizer
Point carries out rational formula, and per mu yield is difficult to improve.
