Problems solved by technology

In November 2015, the Ministry of Agriculture issued the "Guiding Opinions on the Structural Adjustment of Feed Rapeseed in the "Sickle Bend" Area" pointing out that the current supply of feed rapeseed in my country exceeds the demand, and the planting efficiency is reduced. It is urgent to optimize the planting structure and regional layout.

Embodiment 1

[0028] 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.

[0029] The selected feed rapeseed variety is Huayouza 62, a new variety of rapeseed cultivated by Huazhong Agricultural University, a three-line hybrid of Brassica oleracea semiwinter cytoplasmic male sterile, with an erucic acid content of 0.10% and a mea...

Embodiment 2

[0038] 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.

[0039] In order to better compare the effects of various soil amendments on the yield of forage rapeseed, the experiments were carried out on basically homogeneous land, and each test field was separated from each other by a certain distance.

[0040] In this embodiment, the selection of forage rape variety, sowing and harvesting time are all the same as in Embodiment 1.

Embodiment 3

[0045] 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.

[0046] In order to better compare the effects of various soil amendments on the yield of forage rapeseed, the experiments were carried out on basically homogeneous land, and each test field was separated from each other by a certain distance.

[0047] In this embodiment, the selection of forage rape variety, sowing and harvesting time are all the same as in Embodiment 1.

Abstract

The invention discloses a soil replacement improvement method capable of increasing the yield of fodder oilseed rape in added farmland in the loess hilly region. The method includes the steps that 1, a target region of the gully control land reclamation added farmland parcel in the loess hilly region is selected as a land parcel to be improved, and the area S of the selected land parcel to be improved is determined; 2, a preset quantity of Epipleistocene Q3 Malan loess is taken as soil for replacement according to the area of the selected land parcel to be improved; 3, the certain quantity of soil for replacement in the step 2 is smashed until the particle size is smaller than 3 cm, the soil for replacement is uniformly spread on the land parcel to be improved, and sufficient mixing is conducted; 4, farmyard manure and / or compound fertilizer are / is applied as base fertilizer, and ploughing is conducted through a rotary cultivator; 5, fodder oilseed rape is planted on the ploughed improved land parcel. According to the method, materials are convenient to obtain, and the cost is low; the soil texture can be rapidly improved, the water permeability, air permeability and porosity are improved, the soil tilth is improved, and the quality and yield of fodder oilseed rape 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 output of cultivated land, fodder, and rapeseed 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 ear...
