Description
Technical field
The utility model is related to a kind of farm precision planting production equipment field, more particularly, to a kind of for cotton planting
Bivariate fertilizer apparatus.
Background technology
Accurate agricultural (precision agriculture), as the effective development pattern of sustainable agriculture, becomes in recent years
Hot fields for research of agricultural science in the world.Its implication refers to using remote sensing technology, GIS-Geographic Information System, global positioning system
The information technologies such as system, on the basis of positioning acquisition ground block message, according to plot soil fertility, crop disease and insect, weeds, yield
Deng the difference in the time and space, carry out being accurately positioned by agriculture requirement, variable is cultivated, variable fertilization, variable are poured water, variable
The agrotechnical adjustment such as medication and managing, optimizes to greatest extent using every countryside tax system, to obtain maximum output and
Big economic benefit.Accurate agricultural is conducive to improving agricultural output and quality, efficient utilization resource, protecting agriculture ecology ring simultaneously
Border, the agricultural natural resource such as protection soil, reduces the pollution to environment, represents the developing direction of agricultural.
Due to fertilizer cost in countryside tax system the larger proportion of occupation ratio, and the input amount of chemical fertilizer is direct with utilization rate
Impact Agricultural Output, farmers' income and environmental quality, therefore, variable fertilization technology is important group in accurate agricultural operating system
Become one of part.
Reasonably there is very positive meaning to China's agricultural development using chemical fertilizer and research fertilizer practice.Implement on demand
Variable fertilization, permissible, it is economical, social and ecological benefits are notable.At present, the control mode being abroad used for variable fertilization mainly has
Two kinds, that is, real-time control fertilising and prescription information control fertilising.These mechanism controls difficulty are big, and price is high, directly introduce and are difficult to
Apply at home.Therefore, it is badly in need of developing the variable-rate fertilization adapting to China's development need.
Xinjiang is the maximum cotton production areas of China, 20,000,000 mu about of cotton in Xinjiang cultivated area in 2010, cotton in Xinjiang
Production has the features such as Mechanization Level is high, production scale is big.It is known that Cotton fertilization divides base manure and breeding time to topdress
Two kinds of forms, are typically used as base manure by the 70%～80% of the 30%～40% of nitrogenous fertilizer and phosphate fertilizer.Clay fertilizer or the dregs of fat etc. have simultaneously
Machine fertilizer also should apply in basal dressing.With the development of water-saving irrigation, typically soluble good nitrogenous fertilizer and phosphate fertilizer are applied with water droplet
Carrying out breeding time topdresses.In recent years, Xinjiang particularly formation's agricultural, the precision agriculture with drip irrigation technique as core have developed rapidly,
Have been carried out test and the popularization of cotton cultivation with film mulched drip irrigation fertilising.Test shows, under-film drip irrigation fertilising improves to a certain extent
Utilization rate of fertilizer, decreases fixation in soil for the nutrient and loss, is conducive to culture fertility.But, existing result also indicates that,
On the one hand, the fertilizer effect of drip irrigation for cotton fertilising is exaggerated certain aspects of；On the other hand, viewpoint in the past thinks and takes with water droplet fertilizer letter
Efficiently, it is wrong for all can applying with water droplet and abandon basal dressing.
Domestic variable fertilization technology is started late, and Variable Fertilization System has stronger crops specific aim and region
Property, suitable China different geographical and different crops cropping pattern, and it is in the experimental study stage, do not carry out land for growing field crops and push away
Extensively.And domestic research and development and the variable-rate fertilization introduced are primarily adapted for use in northeast, the corn and soybean of East China, wheat etc. and make
The variable fertilization of thing, the cotton variable-rate fertilization for Xinjiang cotton is still in blank；There is ground with northeast, North China in Xinjiang
Many difference such as domain, agronomy, weather, therefore study automatic variable fertilizing equipment in the urgent need to the regional characteristics with reference to cotton in Xinjiang.
