Abstract
The invention discloses a rice mechanical dry direct sowing culture method for yellow river delta saline-alkali soil. The method includes the steps of variety selection, land preparation, sowing, water management, fertilization, weed disaster prevention and treatment and pest control. A variety which is good in saline-alkali resistance, high in germination potential and resistant to lodging is selected; the sowing time is mid-to-late May, and the dry seed sowing amount ranges from 8 kg/mu to 9 kg/mu; watering is conducted in advance for salt leaching and alkali pressing according to the water management mode; in the step of weed disease prevention and treatment, phragmites australis is prevented before sowing; in the step of pest control, water earthworms need to be prevented. Based on an existing rice mechanical dry direct sowing culture method, all the aspects are improved, the corollary culture technology specially for rice mechanical dry direct sowing of the yellow river delta saline-alkali soil is formed, and therefore technical supports are provided for farmers in the region to plant rice. The method has the advantages of saving time, labor, water and cost, increasing the effect and the like, and has important significance in improving the saline-alkali soil, improving agricultural production efficiency and increasing the yield of grain crops.
Description
Technical field
The present invention relates to a kind of rice cultivating technique, be specifically related to a kind of paddy machinery direct-sowing dry cultivation method being suitable for Saline-alkaline Soils of Yellow River Delta, belong to agricultural technology field.
Background technology
Saline-alkaline Soils of Yellow River Delta area about 6,000,000 mu, near the new alluvial plain in direction, river mouth, after farming, very easily the accumulation of salt in the surface soil is degenerated, and is the main source of secondary salinization of land, about has 5% agricultural land to become heavy saline or saline-alkali wasteland because of the accumulation of salt in the surface soil every year.Agricultural production practice for many years proves, by rice cultivation, to wash salt pressure alkali, effectively can improve saline land, severe, moderate saline-alkali soil are improved as slight alkaline land, and crop yield improves year by year, and alkaline land improving is land with high stable yield the most at last.Therefore, paddy rice is the pioneer crop in improvement saline land.According to interrelated data display, current Saline-alkaline Soils of Yellow River Delta preferential species rice area reaches more than 100 ten thousand mu, and belongs to a last month of spring rice district, and therefore rice industry development potentiality is huge.
In recent years, the contradiction that the many people in ground, Delta Region of The Yellow River are few, rural laborer is seriously deficient, and rice transplantation by hand cost is high, and therefore paddy rice gently simplifies to produce becomes inevitable development trend.But still lack ripe corresponding cultivation techniques at present.
Direct sowing on dry paddy field culture technique refers to that field is in drought and water shortage situation, applies base manure through plow harrow, and dry kind is directly sown into land for growing field crops, then harrow mud and cover seed rice, utilize natural precipitation or irrigation to reach the moistening seed rice that makes in field to germinate, after emerging, by one of paddy rice Routine Management new culture technique.Cause early rice by the field of sowing in season, not take technique can sow by season in spring drought lack of water, once there be rainfall, after ground moistening, seed just can be emerged growth, both can catch up with season, can avoid again make morning and put famine.Direct sowing on dry paddy field culture technique has drought resisting, cold-resistant, water saving, saving of labor, laborsaving, volume increase, environmental protection, damage by disease and insect alleviates, ripening rate improves, advantage easy and simple to handle etc.
At present, direct sowing on dry paddy field culture technique is promoted the use of in non-saline and alkaline ground at present, but does not also use on saline land.The paddy machinery direct-sowing dry cultivation method in existing non-saline land comprises wholely, sowing, water management, fertilising, prevention and control of weeds, the extermination of disease and insect pest etc.The sowing time wherein sowed, the dry seeds amount of broadcasting was 11-12kg/ mu after June 17.Fertilization mode is: mu executes zinc fertilizer 1.5kg, nitrogen-phosphorus-potassium compound fertilizer 30-35kg as base fertilizer.Before and after 3 leaf phases, mu executes tillering fertilizer urea about 7.5kg, executes tillering fertilizer urea about 12.5kg again, panicle spike primordium differentiation stage, impose urea about 10kg after 10 days.Crop smothering management comprises Seal treatment and the common weeds in dry land water rice field are prevented and kill off in cauline leaf process.Disease control Major Diseases comprises prevents and treats banded sclerotial blight and rice blast.Pest control comprises control snout moth's larva, rice fulgorid etc.Aforesaid way is not suitable for the paddy machinery direct-sowing dry cultivation in saline land.
Summary of the invention
Lack the problem of paddy rice corresponding cultivation techniques for Saline-alkaline Soils of Yellow River Delta, the invention provides a kind of Saline-alkaline Soils of Yellow River Delta paddy machinery direct-sowing dry cultivation method.The method have save time, saving of labor, water saving, abridged edition, the plurality of advantages such as synergy, for improvement saline land, improve agricultural production efficiency, increase cereal crops output and be significant.
