Problems solved by technology

[0003] The current engineering treatment methods for transforming paddy fields on dry and sandy land often result in low productivity of the soil configuration after transformation, especially when abandoning wasteland and rotating crops, the function of water and fertilizer conservation is low, and the utilization rate of water sources is low, which is very prone to plowing. Bottom water leakage and nutrient loss lead to poor long-term water and fertilizer retention after soil improvement

Embodiment 1

[0040] Embodiment 1-a kind of dry, sandy land is transformed into the water conservation and fertilizer conservation treatment method of paddy field, comprises the following steps:

[0041] Step 1: Peel off the plowing layer: peel off the topsoil plowing layer and soil rock layer in dry and sandy land, and the average height of the peeling is 33cm;

[0042] Step 2: Rolling for the first time: After leveling the stripped ground, use an 18-ton road roller to carry out the first two mechanical compaction treatments, with a compaction degree of 85%, forming an average 11cm plow bottom layer, and using a market Add water to the water-retaining material, dilute and mix it with a material-to-liquid ratio of 1:20kg / l, spray it on the surface of the plow bottom layer by spraying, and let it stand to dry;

[0043] Step 3: Covering with water-retaining material: dry-spread water-retaining material on the surface of the plow bottom layer to make it evenly cover the surface of the plow bot...

Embodiment 2

[0048] Embodiment 2-a kind of dry land is transformed into paddy field water conservation and fertilizer conservation and fertilizer conservation treatment method, comprises the following steps:

[0049] In Fuchang Village, Haikou City, Hainan, 4 adjacent dry land plots that had not been planted with crops and had poor water retention were randomly selected as experimental plots 1 to 4, with an area of ​​215 square meters;

[0050] Experimental field block 1 carries out the following treatment methods for transforming paddy fields,

[0051] Step 1: Peel off the plowing layer: peel off the topsoil plowing layer and the soil-rock layer of the dry land plot, with an average height of 35 cm; follow the principle of first deep and then shallow, from top to bottom, layered and segmented, and base the substrate according to the drawings After the elevation is measured, after stripping to the design bottom elevation, the edge of the field is trimmed and the bottom is leveled, and the ...

Embodiment 3

[0065] Embodiment 3-a kind of treatment method for water conservation, water conservation and fertilizer conservation and fertilizer conservation by transforming sandy land into paddy fields, comprising the following steps:

[0066] Randomly select adjacent unplanted crops and poor water retention sandy land plots in Danzhou, Hainan, as the experimental plot 3, with an area of ​​268 square meters; the following treatment methods for transforming paddy fields were carried out:

[0067] Step 1: Peel off the plowing layer: peel off the topsoil plowing layer and the soil-rock layer of the sandy field, with an average peeling height of 33 cm; follow the principle of first deep and then shallow, from top to bottom, layered and segmented, and follow the drawings to The base elevation is measured. After stripping to the design bottom elevation, the edge of the field is trimmed and the bottom is leveled. The stripped soil is stored in a designated place for subsequent backfilling;

Abstract

The invention provides a treatment method for water conservation, water conservation and fertilizer conservation and fertilizer conservation for transforming dry and sandy land into paddy fields, comprising: 1) peeling off the cultivated layer, and the peeling height is ≥ 30 cm; 2) first rolling: the first time 2 to 3 The first round of compaction treatment, the compaction degree is ≥85%, forming the plow bottom layer, and the water-retaining material is diluted and sprayed; 3) Water-retaining material covering: dry-laying water-retaining material; 4) The second backfill: backfill with 10-20% of the original soil, cover Soil improvement additives; backfill with 15-25% of the original soil; 5) second rolling: second 2-3 times of compaction; 6) second backfill: backfill with 55-75% of the original soil; 7 ) Rotary tillage: add organic fertilizer, trace element raw materials and water-retaining materials, perform dry rotation and 2 times of water rotation to form a plowing soil layer; the method for transforming dry and sandy land into paddy fields in the present invention can effectively maintain the long-term water retention of the transformed paddy fields Fertilizer function, saving irrigation water and planting fertilizer costs, and promoting plant root growth, increasing crop production.

Description

technical field [0001] The invention relates to the technical field of land management, in particular to a water-saving and fertilizer-saving treatment method for transforming dry and sandy land into paddy fields. Background technique [0002] With the increasingly prominent contradiction between human and land needs, especially the demand for cultivated land resources, in order to implement the requirements of "occupying the superior and supplementing the superior, occupying paddy fields and replenishing paddy fields", the transformation of cultivated land projects has been gradually carried out to realize the improvement of cultivated land resources. balance of compensation. The transformation of paddy fields in water-deficient areas with little rainfall and hillside areas with severe desertification is the main difficulty in the transformation of cultivated land. After the paddy fields are transformed, whether the soil fertility level is improved depends on whether the s...
