Problems solved by technology

[0003] The technical problem to be solved and the technical task proposed by the present invention are to overcome the defect that the existing paddy rice may cause inconsistent final maturation due to the inconsistent growth of seedling tiller buds, and provide a tiller control method that promotes consistent growth of rice tiller buds, and at the same time Changing the growing season of hybrid rice to increase planting frequency

example 1

[0028] Example 1: In Xinchang, Zhejiang Province on October 17, 2009, the pregerminated seeds (Yongyou No. 9) were sown on the seedbed in the transparent greenhouse and cultivated until they became young seedlings on November 25, 2009, and then transplanted to the same transparent greenhouse The seedlings in the greenhouse are grown into seedlings, and the transparent greenhouse and the transparent shed are ventilated for 1 hour every day at noon. The temperature in the transparent greenhouse is controlled at 4-8°C. The seedlings are transplanted in the rice field on March 28, 2010, until May In the second half of the year, 47 sins were separated. Then store water in the paddy field, submerge about half of the tiller buds below the water surface, spray chlormequat to the tiller buds above the water surface from 10:00 to 10:30 am according to the conventional method, and store water in the field at 14:00. The shorter tiller buds are exposed to grow together with the higher till...

[0029] Example 2: On October 17, 2009, in Xinchang, Zhejiang, the pregerminated seeds (Yongyou No. 9) were sown on the seedbed in the transparent greenhouse (the seedbed used a paddy field hotbed) and cultivated until it became a seedling on November 25, 2009. The seedlings are transplanted to another seedling field in another transparent greenhouse (the seedling field adopts a paddy field hotbed) to become seedlings. During the period, the transparent greenhouse and the transparent greenhouse are ventilated for 1 hour at noon every day, and the temperature in the transparent greenhouse is controlled at 7-10°C. On March 28, 2010, the seedlings were transplanted in the paddy field, and 53 sins were separated by the end of May. Then store water in the paddy field, submerge about 40% of the tiller buds below the water surface, spray chlormequat to the tiller buds above the water surface from 9:00 to 9:30 in the morning according to the conventional method, and spray chlormequat to...

Abstract

The invention discloses a tiller control method for promoting consistent growth of rice tillers, belonging to a planting method of grain crops. At present, inconsistency growth of rice tillers may cause the inconsistent ripening of rice. The invention provides the tiller control method for promoting the consistent growth of rice tillers, which is characterized by comprising the followings steps of: transplanting rice seedlings in rice fields; storing water in the rice fields in the middle or post period of tillering to sink lower tillers in water and expose higher tillers above the water level; then spraying chlormequat for the tillers above the water level; and draining water in the rice fields in 3-12 hours after spraying the chlormequat to expose the lower tillers and enable the lower tillers to grow and ripen with the higher tillers. With the method, the growth of the higher tillers above the water level is restrained through spraying the chlormequat, and the consistent growth andripening of the tillers are promoted as the lower tillers under water level can normally grow due to being not sprayed with chlormequat.

Description

technical field [0001] The invention belongs to a planting method of grain crops, in particular to a method for promoting uniform maturation of rice by controlling tillering of seedlings. Background technique [0002] After the seedlings are transplanted to the paddy field, there is a tillering process, whether it is a conventional seedling that can produce 10-15 tiller buds or a special seedling raising method (such as the applicant’s invention patent application No. 201010204311.1) so that the number of tillers reaches the conventional For 3-5 times the seedlings, the tiller buds that branch out earlier have a higher growth potential, and the tiller buds that branch out later have a shorter growth potential. The inconsistent growth of the tiller buds may lead to inconsistent final maturation of rice, especially the The inconsistency in final maturation of rice was more serious when there were more tiller buds. Contents of the invention [0003] The technical problem to ...
