Ecologically sustainable organic wheat planting method

One of the most important yield-increasing measures in agricultural production practice is the application of nitrogen f...

(1) select wheat to plant wheat field, and wheat field preferentially selects the place that has good water source nearby, and wheat field is carried out ridge arrangement and forms some connected field pieces. Plant nitrogen-fixing plants (such as broad beans) and nectar plants on the ridges between fields, such as fruit trees, Polygonaceae plants, rape, mustard, zucchini, clover, stone dragon and milk vetch, etc., to increase the biodiversity in the wheat field, Establishing the living environment of natural enemies of pests through various methods is conducive to the realization of efficient biological integrated control of wheat diseases and insect pests. Embankment slopes can be left on the edge of the field ridge, and different types of food crops, such as melons and rapeseed, can be mixed on the embankment slopes to increase the biodiversity in the wheat field.

(2) around each field piece, in the field piece interior excavation ditches, excavation ditch produces redundant soil and can be used for building the ridge and embankment between the field pieces, the ditches of adjacent field pieces are interconnected and The ditches connected to the fields form a drop in turn, and the lowest water level ditch and the highest water level ditch are pumped by pumping stations to form a circulating water system. On the one hand, the construction of ditches is conducive to storing rainwater in the rainy season, conveniently providing water sources for wheat planting, and reducing the exploitation of groundwater sources. Moreover, water recharge wells can be set at the lowest water level ditches to recharge ecological water. Raise the groundwater level to realize a real "underground water reservoir", so as to realize the sustainable development of the main wheat producing areas; on the other hand, it also helps to drain the wheat fields and ensure the dry conditions required for the specific period of wheat growth. At the same time, aquaculture can be carried out in the ditch, such as shrimp or fish farming, which will help increase output. At this time, the ditch needs to be properly deepened and widened. Generally, the width is about 4m and the depth is about 1.5m.

(5) the organic fertilizer is dissolved in the water body of the ditch, and the water replenishment and topdressing are carried out to each field block successively by the mode of circulating flood irrigation and receding water. A method that is more c...
