Description
Technical Field
The invention belongs to the technical field of saline-alkali soil rice planting, and particularly relates to a seedling raising method for rice planted in saline-alkali soil.
Background
The area of the saline-alkali soil is wide in the world, and according to incomplete statistics of textbook organization and grain farming organization of the united nations, the area of the saline-alkali soil is 9.5 hundred million hectares all over the world, wherein China is close to 1 hundred million hectares, namely 15 hundred million acres. Wherein, 2.8 hundred million mu saline-alkali soil is in urgent need of transformation, and 1.4 hundred million mu of the 2.8 hundred million mu salinized land is within 18 hundred million mu of cultivated land red line, and the rest 1.4 hundred million mu is the unused land defined by the ministry of land resources. With the increase of urban area, the cultivated land area is continuously reduced, and the population is continuously increased, so that people face the serious challenge of food.
The saline-alkali soil has poor natural conditions and high salinity content, so that the saline-alkali soil can be suitable for few crops growing in the saline-alkali soil. Rice is the main food crop in China, and rice is staple food for people with nearly 2/3 nationwide population. The rice cultivation area accounts for 1/3 of the grain planting area, but the yield accounts for about 40 percent of the total grain yield. Therefore, the rice production has extremely important significance in the aspect of guaranteeing the safe supply of food in China. The research proves that the saline-alkali tolerant rice has certain saline-alkali tolerant capacity, can effectively reduce the saline-alkali degree of soil and achieves the effect of improving the saline-alkali soil. The saline-alkali soil is poor in soil fertility, low in organic matter content and poor in soil aggregate structure, and people can improve the soil fertility and increase the rice yield through blind fertilization.
The rice seedling raising is an important step in the rice planting process, and how to make the rice seedling raising work under the condition of saline-alkali soil becomes the key point for guaranteeing the rice planting in the saline-alkali soil. Therefore, the research on the rice seedling raising technology in the saline-alkali soil is particularly necessary.

(4) After applying the fertilizer, ploughing the soil to uniformly mix the fertilizer and the soil conditioner, wherein the ploughing depth is 0-25cm, and irrigating until the soil is saturated after ploughing, and the water depth is 3-5 cm;
(5) performing film enclosing along the rice seedling bed, selecting 120-plus-130 cm bamboo poles, inserting one bamboo pole every two meters, fixing the clinker film with the width of 1 meter on the bamboo poles along the circumference of the rice seedling bed, and fixing the clinker film with soil below to ensure that no gap exists;
(6) making seedling beds one day before sowing, wherein the width of each seedling bed is 1.2-1.5m, the moisture on the seedling beds is not too much, and a distance of 25-30cm is reserved between the seedling beds;
(7) the seeding density is not too high, the seeding amount per square meter is 180-200g, the seeds are pressed by a flat plate, the depth is not too deep, so that the seeds do not sprout, and the seeds are not exposed on the ground surface;
(8) irrigating the rice for the first time after the rice is subjected to needle setting until the rice completely submerges a seedling bed, and the rice should not be too deep;
(9) applying the fertilizer to two leaves and one heart, selecting 3-4kg of urea per mu, and ensuring the field water depth to be 2-3 cm;
(10) transplanting until the rice seedling has three leaves and one heart or four leaves and one heart.
