Description

Renewable rice one-supplement yield-increasing and efficiency-increasing method based on efficient utilization of light energy
Technical Field
The invention belongs to the technical field of crop planting, and particularly relates to a method for increasing yield and efficiency of ratoon rice based on efficient utilization of light energy.
Background
Rice is one of the most important grain crops in China and even all over the world, the yield per unit of rice is continuously and greatly improved by means of technological progress, and the rice is a necessary choice (Yuanyongping, 2015) for solving the global grain safety problem. Since the last 80 s, super rice breeding plans are implemented successively by countries and institutions such as Japan and International Rice institute, but the super rice breeding plans are difficult to popularize in a large area due to the problems of high difficulty and poor technical route, and the bred varieties are difficult to popularize in a large area due to the problems of rice quality, stress resistance, fructification rate and the like, and are not successful so far. The 1996 Ministry of agriculture officially sets up a China super rice breeding program to meet the target service of increasing food demand in China. Wherein, the rice in one season sets a four-stage yield target: 10.5t/hm2,12t/hm2,13.5t/hm2And 15.0t/hm2. In 1997, Yuanlong proposed a technical route of super-high-yield breeding of rice, which combines morphological improvement and heterosis utilization. On the basis, a four-good matching technical system matched with four factors of 'fine variety, fine method, fine field and fine state' is further provided for large-area ultra-high-yield demonstration planting of the super hybrid rice. Under these technical guidelines, the goal of super hybrid rice breeding at each stage has been achieved successively. Breakthrough 667m in 20002700 kilograms of products are produced; 667m 20042Produce 800 kilograms; 2011 667m2Producing 900 kilograms; realize 667m in 201421026.7 kg is produced, and the average 667m of large area demonstration is broken through for the first time2Producing 1000 kg of target; in 2018, 667m is realized21152.3 kg is produced, the highest yield is 667m2The yield was 1209.5 kg. The large-area balanced yield increase of the hybrid rice makes unique important contribution to the food safety of China. However, the potential for further increasing the yield per unit area has been limited, and further increase in rice yield should be achieved by innovating and improving existing cultivation techniques.
The regenerated rice is a rice cropping system which utilizes axillary buds on rice stakes after first season rice is harvested to germinate into seedlings, and the seedlings are subjected to scion and fructification through scientific management to harvest one season. The method has the advantages of short growth period, high daily yield, seed saving, labor saving, water saving, labor adjustment, low production cost, high benefit and the like, and is one of measures for improving the multiple cropping index and increasing the rice yield and the economic income of a rice field in a rice area in south China where the heat of one-season rice is excessive and the heat of double-season rice is insufficient and a rice field with only one-season middle rice in the double-season rice area. However, with the development of the ratooning rice technology in China, particularly with the demonstration and popularization of mechanical transplanting and mechanical harvesting on ratooning rice in recent years, some problems are also generated, wherein partial rice piles are directly damaged after a mechanical harvester for first season rice, the germination and growth of ratooning buds are seriously influenced, and the ratooning rice technology is a key factor for restricting the further improvement of the yield of ratooning rice in recent years. Meanwhile, the regenerated rice plants are short, and cannot be completely sealed after the group reaches the maximum leaf area, so that part of solar rays directly irradiate the soil surface, part of light energy is wasted, and light energy is not fully utilized. Therefore, how to reduce the mechanical rolling loss and the light energy waste in the production process of the regenerated rice is an effective way for further and greatly improving the unit yield and the total yield.
