Embodiment 1

[0029] Firstly, the test field is selected, the area of ​​the test field is measured, and the amount of foreign soil is calculated according to the area of ​​the test field and the thickness of the prepared covering soil. In this embodiment, take Malan loess 5cm (X5), red clay (L5), and undisturbed soil (YZT) respectively, and plant 3 unit areas of each type of covering soil and thickness (that is, the standard test field size, which can be selected according to needs, such as Can be selected as 100 square meters or 1 mu), the first unit area is applied with farmyard manure, the second unit area is applied with compound fertilizer, and the third unit area is applied with a mixture of farmyard manure and compound fertilizer.

[0030] The selected corn variety is Demeiya No. 3, an annual gramineous herb with early maturity, high quality, disease resistance, compact plant type, well-developed root system, and strong lodging resistance. The plant height is about 260cm, the ear heig...

Embodiment 2

[0039] In the present embodiment, take Malan loess 10cm (X10) respectively; Red clay 10cm (L10); Every kind of covering soil type and thickness plant 3 unit areas (that is, the size of the standard test field, which can be selected according to needs, for example, can be selected as 100 square meters or 1 mu), the first unit area is applied with farmyard manure, the second unit area is applied with compound fertilizer, and the third unit area is applied with a mixture of farmyard manure and compound fertilizer.

[0040] In order to better compare the effects of various soil amendments on maize yield, the experiments were carried out on basically homogeneous land, and the experimental fields were separated from each other by a certain distance.

[0041] In the present embodiment, the selection of corn variety, sowing and harvesting time are all the same as in Embodiment 1.

Embodiment 3

[0047] In the present embodiment, take Malan loess 15cm (X15) respectively; Red clay 15cm (L15); Every kind of covering soil type and thickness plant 3 unit areas (that is, the standard test field size, which can be selected according to needs, for example, can be selected as 100 square meters or 1 mu), the first unit area is applied with farmyard manure, the second unit area is applied with compound fertilizer, and the third unit area is applied with a mixture of farmyard manure and compound fertilizer.

[0048] In order to better compare the effects of various soil amendments on maize yield, the experiments were carried out on basically homogeneous land, and the experimental fields were separated from each other by a certain distance.

Abstract

The invention discloses a foreign soil improvement method for improving the yield of corn in a cultivation land newly added in a loess hilly region. The method includes the following steps that 1, a target region of the cultivation land and field newly added in a loess hilly region is selected as an improved land parcel, and the area S of the selected improved land parcel is determined; 2, according to the area of the selected improved land parcel, a predetermined amount of epipleistocene Q3 Malan loess serves as foreign soil; 3, the predetermined amount of foreign soil in the step 2 is crushed until the particle size is smaller than 3 cm, the foreign soil is uniformly laid on a to-be-improved field parcel, and mixing is fully conducted; 4, farmyard manure and / or a compound fertilizer are / is applied to serve as a base fertilizer, and a rotary cultivator is used for ploughing; 5, after ploughing, core is planted in the improved land parcel. According to the method, materials are easy to obtain, the cost is low, the soil texture can be rapidly improved, the water and air permeability and the porosity are improved, the ploughing capacity of soil is improved, and the quality of the yield of the core are improved.

Description

technical field [0001] The invention belongs to the field of agriculture and land engineering, and in particular relates to a soil improvement method for increasing the yield of corn in newly-added cultivated land in loess hilly areas. Background technique [0002] The hilly and gully area of ​​the Loess Plateau is criss-crossed with cross-beams and ravines, and is the most serious area of ​​soil erosion in my country. In recent years, the central government has supported major engineering projects of gully land reclamation and land consolidation in Yan'an, Shaanxi, providing new opportunities for optimizing the agricultural structure of the Loess Plateau and improving land use efficiency and ecological effects. The construction of new cultivated land and its rapid maturation are important foundations for gully land consolidation and sustainable land use. [0003] The researches on the rapid maturation and quality improvement of cultivated land at home and abroad are earlie...
