Problems solved by technology

[0004] The one-time fertilization that has been tried in recent years saves labor and labor. Although some studies have shown that it can increase wheat yield, reduce nitrogen loss, and improve nitrogen use efficiency, the nutrient release of slow and controlled-release fertilizers that one-time fertilization relies on is affected by soil moisture, temperature, etc. Influenced by various factors, the effects of climate and soil conditions in different regions are unstable, coupled with price and cost, there is still some controversy in one-time fertilization

Embodiment 1

[0034] (1) Wheat planting in wide and narrow rows: Wheat is sown in wide and narrow rows, with the row spacing of the wide rows being 30 cm and the row spacing of the narrow rows being 16 cm.

[0035] (2) Combination of mixed application of basal fertilizer to plow layer and concentrated deep application: basal fertilizer was applied in narrow rows before wheat sowing, accounting for 60% of the total nitrogen application amount by weight.

[0036] Wherein 60% of the base fertilizer by weight is evenly spread on the narrow row, and the soil is mixed with the base fertilizer by mechanical rotary tillage. The depth of the rotary tillage is 10 cm. Apply the basal fertilizer of remaining 40% weight, 3 centimeters of ditch widths, 9 centimeters of ditch depths, backfill ditch soil and bury fertilizer after basal fertilizer is used;

[0037] (3) Sow wheat on both sides of the narrow row, the sowing depth is 2 cm, and suppress only in the narrow row after sowing.

Abstract

The invention provides a one-base and one-topdressing deep fertilization method for wheat. The method comprises the following steps: (1) alternately dividing a land to be sown with wheat into wide rows and narrow rows in the front-back direction, and arranging the wide rows and the narrow rows in the left-right direction; (2) applying a base fertilizer in the narrow rows before wheat sowing; (3) sowing wheat on two sides of the narrow rows; and (4) after wheat turns green and before jointing, digging fertilizing furrows in the middles of the wide rows for topdressing, and backfilling and compacting furrow soil. Preferably, the step (2) specifically comprises the following steps: uniformly spreading a part of the base fertilizer on the narrow rows, performing rotary tillage on the narrow rows, furrowing in the middles of the narrow rows, intensively applying the residual base fertilizer, and backfilling the furrow soil and burying the fertilizer. According to the method, the fertilization frequency can be reduced, labor and effort are saved, the nutrient requirement of the wheat in the whole growth period is met, resource waste and environmental risks caused by fertilizer spreading are effectively eliminated, high yield and efficiency improvement of the wheat are guaranteed, design is ingenious, operation is easy and convenient, cost is low, and the method is suitable for large-scale application and popularization.

Description

technical field [0001] The invention relates to the technical field of crop planting, in particular to the technical field of wheat fertilization, and specifically refers to a "one base, one topping" deep layer fertilization method for wheat. Background technique [0002] Wheat is the second largest food crop in the world, and fertilization can significantly increase wheat production. However, excessive fertilization will not only cause a decline in economic benefits, but also affect resources and the environment. Focusing on reducing nitrogen and improving efficiency and improving fertilizer use efficiency, current research is mostly focused on green fertilizer products, rational fertilizer operation and precise application technology research to meet the needs of wheat growth. [0003] However, at present, domestic wheat fertilization is still dominated by artificial or mechanical surface application. Nitrogen fertilizer is wasted due to ammonia volatilization or runoff l...
