Problems solved by technology

The application of controlled-release fertilizers is becoming more and more common, but its relatively high price discourages farmers, and previous fertilizer products and technologies cannot meet the needs of crops throughout the growth period
For example, Chinese patent CN1609075 "production method of slow/controlled release fertilizer for winter wheat" is very easy to cause late-stage defertilization and relatively high price during the relatively long growth period of wheat; Chinese patent CN101492319 "special fer

Embodiment 3

[0076] Example 3: Simplified Fertilization Method for Annual Wheat and Corn Rotation

[0077] Under the condition of returning the previous crop of corn stalks to the field, after using mechanical deep plowing to prepare the land, perform the following operations:

[0078] 1) Wheat slow-release fertilizer (I) and wheat seeds are applied to the field by the wheat sowing and fertilizing all-in-one machine simultaneously, and the fertilizer is below the seed side, vertically separated from the seed by 6cm, and laterally separated by 5cm, and the fertilization amount is 55kg / mu;

[0079] 2) Apply urea (N content is 46%) 18kg / mu, potassium chloride (K 2 O content is 60%) 6kg / mu, and the mode of application is to cover soil after ditching between wheat rows with columbine, and the depth of the ditch is 7cm;

[0080] 3) Within 10 days after the jointing stage of corn, apply corn slow-release fertilizer (IV) at one time, and the fertilizer rate is 52kg / mu. 10cm fertilization ditch,...

Abstract

The invention relates to a simplified fertilizer application method of wheat and corn crop rotation anniversary, which is changed into an anniversary fertilizer application method that fertilizer application is carried out twice in a wheat season and fertilizer application is carried out once in a corn season from a traditional habitual fertilizer application method that the fertilizer application is carried out twice or three times in a wheat season and fertilizer application is carried out more than twice in a corn season. Wheat slow release fertilizer and corn slow release fertilizer are applied on crops, which not only can plan and consider the nutrient requirement of the anniversary of two-crop crops and ensure dependable crop and increasing yield of the crops but also can simplify fertilizer application times to a great extend and save labor force.

Description

technical field [0001] The invention relates to a simplified fertilization method for annual wheat and corn rotations, and belongs to the technical field of long-acting slow-release fertilizers and their applications. Background technique [0002] North China is the main grain producing area in my country, especially the winter wheat-summer corn rotation system, which is a typical planting system of two crops a year, is the main grain planting method in the Huanghuaihai region of North China. The food products produced under the conditions have greatly guaranteed the food security of our country. Winter wheat in this area is generally sown in early October and harvested in early or mid-June. Summer corn is sown in mid-June and harvested in late September or early October. It accounts for more than 50% of the contribution in the process of increasing grain yield, so the distribution of fertilizer in this rotation cycle of winter wheat and summer maize is particularly importan...
