Annual simplified fertilizing method of wheat and peanut in hilly land

Abstract

The invention relates to an annual simplified fertilizing method of wheat and peanut in a hilly land. The method comprises the following steps that azophoska is uniformly spread on the earth's surface on 1 to 2 days before the wheat is sowed; meanwhile microelement is applied; the applied amount of nitrogen fertilizer accounts for 20 to 30 percent of a total nutrient of required nitrogen fertilizer per mu; the applied amount of phosphatic fertilizer accounts for 60 to 70 percent of the total nutrient of required phosphatic per mu; the applied amount of potash fertilizer accounts for 40 to 50 percent of the total nutrient of required potash fertilizer per mu; the second fertilization is performed in the elongation stage of the wheat, the remaining fertilizer of the required azophoska per mu is applied; according to the annual simplified fertilizing method provided by the invention, the nutrient supply of the wheat in later period is simultaneously considered, meanwhile the basal fertilizer is provided for the following peanut, root nodule nitrogen fixation of the peanut is fully considered, the fertilizer input is reduced, and negative impact on groundwater due to the fact of the excessive fertilizer of the fertilizer nutrient, especially nitrogen nutrient is avoided; compared with the traditional fertilizing method, the method has the advantages that the fertilizer input is reduced by 1 to 2 times, and the labor cost is saved.

Description

technical field [0001] The invention relates to a method for fertilizing winter wheat and summer peanuts, in particular to a method for simplifying the frequency of fertilization by twice-cropping winter wheat and summer peanuts in northern hilly areas, and belongs to the technical field of agricultural fertilization. Background technique [0002] Winter wheat is the main food crop in my country, and peanut is also an important oil crop. Both are the main crops grown in northern my country. Affected by annual caloric resource constraints and ecological regions, as well as traditional planting habits and government guidance, and to effectively alleviate the conflict between grain and oil, intercropping of winter wheat and summer peanuts is an important planting in some northern areas, especially in hilly areas. Way. Affected by the soil-forming parent material, the hilly land is generally sandy soil or loamy soil. The soil of this texture is very suitable for the growth, pod...

Problems solved by technology

The traditional fertilization operation has the following problems: first, the variety of fertilization is single or complicated, and fertilization is relatively random in wheat season and peanut season, and there is no corresponding fertilizer nutrient input according to the needs of crops for various nutrients; second, the time of fertilization Although it is relatively reasonable, the number of times is too high, which is in contradiction with the current situation of decreasing rural labor force. Moreover, some farmers miss the application of topdressing fertilizer because they cannot return to work outside the home, resulting in insufficient supply of nutrient inputs. The existing fertilizer types are basically The quick-acting type lacks slow-release fertilizers or long-acting fertilizers suitable for wheat and peanuts, and cannot meet the nutrient requirements of crops throughout the growth period through one-time use; the third is that when peanuts are topdressed in the later stage, they are already at the beginning of pod formation , Topdressing is not easy to operate, if the method of spreading fertilizer is used, it will lead to serious fertilizer loss and low nutrient utilization rate, and if the method of furrowing is used, it will cause damage to peanut roots and pods, thus affecting the yield

[0004] Chinese patent document CN1561662A (application number: 200410023889.1) discloses the heavy-duty fertilization method before double cropping of wheat and peanuts. This method mainly proposes the ratio of fertilization amount of peanuts after cropping based on the annual nutrient distribution ratio of wheat and peanut intercropping under different fertilization levels. It only accounts for 10%-35%, and such a nutrient amount can be satisfied by the second fertilization of the last stubble wheat, so it will lead to too many times of fertilization, which is inconsistent with the current development trend of light and simplified production. Fertilization methods do not limit the types of fertilizer nutrients. Common quick-acting fertilizers cannot meet the nutrient needs of crops in the longer growth period, and the amount of nitrogen topdressing in the later stages of the wheat season is relatively small, which cannot meet the nutrient needs of wheat in the later stages of growth. Wheat yield Can not guarantee
