Method of raising seedlings by small rice material

Abstract

The invention relates to a method of raising seedlings by small rice material. The method includes: 1, selecting sprout trays, and nailing small wooden sticks into small wooden grids in order to divide each sprout tray into a plurality of small cells; 2, sequentially arranging the small material before seeding, and tying ten pieces of the small material for seeding; 3, seeding in a paddy field, namely making beds after the paddy field is leveled, laying the sprout trays on the beds, laying a thin layer of paddy field mud on the sprout trays, placing the small wooden grids, and sequentially sowing and placing the small material into the small cells with field mud; 4, well managing water and fertilizer in the paddy field phase, and controlling disease and insect damage; 5, sequentially placing a number plate in each tray three days before transplanting; 6, staking seedlings the day before transplanting, clearing the mud adhering to the bottom of each tray, and sequentially placing the trays into a small wooden boat; and 7, carrying the small wooden boat with the seedlings to a large field, and sequentially putting the small material into the large field for convenience of planting. The method has the advantages that pulling the seedlings is avoided, placing the number plates and picking up the seedlings are quick, and error rate is lowered.

Description

technical field [0001] The invention relates to a method for raising seedlings of rice, in particular to a method for raising seedlings of small rice materials. Background technique [0002] Paddy rice is one of the world's three major food crops and one of the most important food crops in my country. Its sown area accounts for about 30% of the country's grain sown area, and its output accounts for more than 40%. Moreover, more than half of the population in China directly feeds on rice. staple food. Rice breeding improvement is an important means to greatly increase rice yield. Rice dwarf breeding in the mid-to-late 1950s and hybrid rice breeding in the 1970s brought about two major leaps in rice yield. From 1961 to 2007, the rice yield in China increased from 2079kg / hm2 to 6341kg / hm2. However, in the process of rice breeding and improvement, it is necessary to plant a large number of parents and hybrid offspring materials. When raising seedlings, it is necessary to go thr...

Problems solved by technology

However, in the process of rice breeding and improvement, it is necessary to plant a large number of parents and hybrid offspring materials. When raising seedlings, it is necessary to go through procedures such as seeding, sowing, placing cards, pulling seedlings, picking seedlings, and rowing seedlings. The steps are complicated, time-consuming, laborious and costly high, easily confused
