Method.
Background technique
Currently, corn is one of China's Three major grain crops, is continued to maintenance with national food security and economy is ensured
Development has important strategic status.Important component of the Maize in Yunnan as Southwestern China maize production region is sowed throughout the year
Area is stably maintained at 22,000,000 mu or more, and is planted in 1000 meters of height above sea level or more plateau embankments and mountainous region river valley mostly
On gentle slope.Yunnan peasant especially lives in concentrated communities the habit that the ethnic group peasant in borderland has hobby maize planting throughout the year
It is used, therefore the production level of corn is of great significance to stablizing local farmers income and shake off poverty and set out on the road to prosperity.
From the point of view of maize culture angle of physiology, nitrogen is the required macronutrient for guaranteeing corn normal growth and development
One of and corn with high yield formed important material base and source of nutrition, therefore corn planting production always be unable to do without contain nitrogen
The fertilizers input of nutrient.However, in production practice if cannot scientifically and rationally applied nitrogen, not only significant wastage nitrogen
Fertilizer, the formation for being unfavorable for corn yield, also will cause serious agricultural non-point source pollution, destroy ecological environment, while also greatly
Increase agriculture production cost, remarkable in economical benefits decline.According to Maize in Yunnan concentrate producing region productive embankment the study found that
There are fertilizing managements it is extensive, low output is of poor benefits the problems such as, and be mainly reflected in that nitrogen fertilizer amount and fertilizing method be not scientific, do not conform to
Reason, in terms of being in particular in following two.On the one hand: nitrogen fertilizer amount is not scientific, input amount is bigger than normal, using mu as production unit, mu
Nitrogen fertilizer application is converted to purity nitrogen (N) generally at 20 kilograms or more, or even having individual fields is more than 30 kilograms, and the input amount of potash fertilizer is tight
Weight is insufficient, and mu potassium application is converted to potassium oxide (K2O) generally lower than 5 kilograms or even some fields not potassium application throughout the year.Another party
Face: fertilization mode is extremely unreasonable, and always according to local traditional habit method, soil first carries out dig reservoir in most of area
(cave), later just and then in the pool (cave) interior basal dressing, however base manure apply down after earthing not in time again, or rainfalls is waited to sow
Earthing is too shallow too thin afterwards.In addition, dressing fertilizer period in corn later period is generally partially early, and the mode of dressing fertilizer still uses jade after rain
Rice root centrostigma is excuted a law or even some fields take broadcast application in the ranks.The above this unreasonable fertilising way causes fertilizer
Waste is serious, and then reduces fertilizer utilization efficiency and influence corn normal growth and development and yield composition.
