Abstract
The invention provides a summer corn prescription seed fertilizer and a fertilization method thereof. The summer corn prescription seed fertilizer comprises the effective components including a nitrogen fertilizer, a phosphate fertilizer, a potash fertilizer, wherein the nitrogen fertilizer is calculated based on N element, the phosphate fertilizer is calculated based on P2O5, and the potash fertilizer is calculated based on K2O, the mass ratio of N, P2O5 and K2O is 18-22 to 8-12 to 8-12. The sowing method comprises the steps of: ditching and applying the seed fertilizer at 4-5cm of one side of a sowing line, wherein the ditch depth is 6-7cm from seeds downwards, and the fertilization quantity is 5.4-6.6kg/mu of the N, 2.4-3.6kg/mu of the P2O5 and 2.4-3.6kg/mu of the K2O, so that the nitrogen-phosphorus-potassium proportion is proper; furthermore, the soil nutrient loss, the unbalance, the non-point source pollution and the soil acidification can be avoided, and the corn yield and the rural income can be increased; and therefore, the summer corn prescription seed fertilizer and the fertilization method thereof are suitable for brunisolic soil in North China.
Description
Technical field:
The present invention relates to a kind of agricultural fertilizer and fertilizing method thereof, particularly a kind of corn formulation seed manure and application process of directly relating to is suitable for northern brown earth soil.
Background technology:
Chinese soil is divided into 12 classes by series takes place, and brown earth is one of them, and brown earth mainly is distributed in the Shandong Peninsula and the peninsula, Liaoning.
The problem that China's Maize Production fertilising in recent years exists is serious day by day, using of northern brunisolic soil corn seed fertilizer on the ground particularly, and nutrient drops into uneven, and utilization rate of fertilizer is low; Peasant's phenomenon ubiquity that blindly applies fertilizer, mainly according to former years custom and fertilizer market value apply fertilizer; Fertilizing method is unreasonable, and fertilizing equipment does not match, and the deep application of fertilizer technology does not obtain big area and promotes, and nitrogen, phosphorus, potassium ratio are unreasonable, cause soil nutrient unbalance, and soil fertility descends; Utilization rate of fertilizer is not high, drop into to increase, and benefit reduces, and influences the raising of corn yield and quality, and application process is improper, causes loss of soil nutrient, unbalance, pollution of area source, soil acidification more and more heavier.
Part peasant household only uses urea for corn fertilizing the time, though replenished nitrogen for like this corn and soil, but replenish nutritive elements such as phosphorus, potassium for corn and soil, can cause the corn grain number per spike to reduce, thousand seed weight descends, and output reduces, and is not resistant to lodging, disease-resistant, pest-resistant power dies down, and disease and pest takes place easily; Corn seed fertilizer application process and site of administration be science not, adopts spread fertilizer over the fields more, and fertilizer loss is more, and utilization ratio reduces, and also has the seedling of burning phenomenon to exist.
Summary of the invention:
It is proper that purpose of the present invention just provides a kind of nitrogen phosphorus potassium proportioning, do not cause loss of soil nutrient, unbalance, pollution of area source, soil acidification, raising corn yield, increases farmers' income, is suitable for corn formulation seed manure and the application process in northern brown earth soil.
The object of the present invention is achieved like this:
A kind of summer corn prescription seed manure, its effective constituent comprises nitrogenous fertilizer, phosphate fertilizer and potash fertilizer, it is characterized in that described nitrogenous fertilizer in the N element, described phosphate fertilizer is with P
2O
5Meter, described potash fertilizer is with K
2The O meter, described N:P

2The mass percent of O is 18-22:8-12:8-12.
N:P of the present invention
2O
5: K
2The mass percent of O is 20:10:10
Nitrogenous fertilizer of the present invention is urea, and the quality percentage composition that is specially N is 46% urea.
Phosphate fertilizer of the present invention is diammonium phosphate, is specially P
2O
5The quality percentage composition be 42%, the quality percentage composition of N is 15% diammonium phosphate.
Potash fertilizer of the present invention is Repone K, is specially K
2The quality percentage composition of O is 60% Repone K.
When the application process of summer corn prescription seed manure of the present invention was sowing, in the place of one side 4-5 centimetre of sowing row, trench digging was used seed manure, and ditch depth is apart from 6-7 centimetre down of seed vertical range, adopted machinery to use, and amount of application is N 5.4-6.6 kg/ mu, P
2O
52.4-3.6 kg/ mu, K
2O 2.4-3.6 kg/ mu.
The present invention compared with prior art has the following advantages:
Owing to adopted rational nitrogen phosphorus potassium proportioning, the soil has been carried out balance fertilizing, can improve grain number per spike and the output of corn, improve the economic benefit of crop, grain number per spike increases 11-12.8%, output increases 15-26.7%, every mu of benefit increases 104-204 unit, can alleviate and the finally detrimentally affect that in the past caused because of lavishment fertilizer of elimination, does not cause loss of soil nutrient, unbalance, pollution of area source, soil acidification, and can improve this season utilization ratio of fertilizer, and can reduce usage quantity significantly.
Owing to adopted optimum fertilizing method, place one side 4-5 centimetre of sowing row, trench digging is used seed manure, ditch depth is apart from 6-7 centimetre down of seed vertical range, can make maize root system fully absorb nutrient, thereby play the effect in strong sprout, for high-yield and high-efficiency is laid a solid foundation, this application process easily realizes by machinery, provides fundamental basis for corn seed fertilizer uses with the exploitation of broadcasting machinery.
In a word, the present invention is according to the growth characteristics of corn, and the prescription seed manure applies fertilizer than peasant habit, improves fertilizer efficiency, promotes seedling growth, increases output.The present invention efficiently provides the fertilizer practice of a science for realizing corn with high yield, has significant effect of increasing production, along with popularizing of mechanization of agriculture, the seed manure of will filling a prescription is combined with agricultural machinery, to have wide actual application value, agricultural machinery agronomy is in conjunction with being China's Modernization Agricultural Development direction, and this technology will have the vast market background in China's Maize Production.
