Technical Field
The embodiment of the invention relates to the technical field of agriculture, in particular to a method for cultivating dry rice seeds.
Background
Upland rice, a cultivated rice suitable for dry land planting, also called dry rice, is a variant of rice, and is widely applicable to cultivated rice growing in boundless dry lands, sloping lands and arid ecological environments. The original cultivation of the dry rice can be traced back to 7000 years, the dry rice is usually planted in mountainous areas of tropical and subtropical zones, sloping fields of semi-mountainous areas, terrace fields or dry lands with less rain in temperate zones, the dry rice and the rice have a plurality of differences in form and physiology, but the dry rice and the rice are generally obvious under the condition of water shortage, the dry rice has more oxygen demand during germination, stronger water absorption and less water demand, the dry rice germinates faster than the rice at the temperature of 15 ℃, the coleoptiles are shorter, the medium stems are longer, the first and second complete leaves are larger, the toxicity resistance to potassium chloride is stronger, the proportion of the coarse roots of the dry rice is larger, the root system is developed and is distributed deeper, uniform fine roots are generated on the main roots, the root crowns are higher, and the drought resistance is strong. The difference of root systems of dry rice and rice planted in a paddy field is not obvious, the dry rice has large leaf area, slow leaf growth, thick middle ribs of leaves, large area of vascular bundles and conduits, thick epidermis, few pores and small thick-walled cells, the characteristics are related to strong drought resistance, and most dry rice varieties have light green leaves and long and drooping leaves.
The dry farming of the rice can fully utilize natural rainfall, so that the planting of the rice is not limited by artificial irrigation, the planting area of the rice can be greatly enlarged, and the yield of the rice is improved; secondly, the method is beneficial to the transformation of low-lying lands, water-sand lands, riversides and mountainous effluent lands, the paddy fields planted in the land blocks lack irrigation conditions, waterlogging is easy to occur in the planted dry land in summer, the perennial grain yield is extremely low, the yield of dry farming of rice can be increased by times, and the economic benefit can be greatly improved; the dry farming of the rice can save a large amount of agricultural water, reduce the production cost and improve the economic benefit because the natural rainfall is fully utilized.
