Low-activity old rice seed planting method

Abstract

The invention relates to the field of rice planting, in particular to a low-activity old rice seed planting method. The method includes the following specific steps: (1) sunning; (2) washing; (3) first seed selection; (4) soaking; 5) germination; (6) seedling field preparation; (7) seeding; (8) water spraying; (9) planting field preparation; (10) base fertilizer application; (11) transplanting; (12) pest control; (13) flowering; (14) harvesting. The enzymes in old seeds are activated to enhance the internal activity and increase the rate of emergence. Seedlings are first planted in a seedlingfield to ensure that the seedlings are germinated before planted in a planting field, to prevent the phenomenon that the old seeds are not germinated after seeding and reduce the loss of growers. Topapplication is conducted during the flowering to accelerate the growth of rice and increase the yield of the rice.

Description

technical field [0001] The invention relates to the field of rice planting, in particular to a method for planting old rice seeds with low vigor. Background technique [0002] Old species refer to seeds that have been stored for more than one year after harvest, while new species refer to seeds harvested in the previous season. Due to the length of storage time, there are certain differences in the nutrients consumed, seed vigor, germination rate, and germination potential during the storage period. The seed vitality, germination rate and germination potential of old species are worse than those of new species; new seeds have chlorophyll in rice husk or rice belt, so a small part of the seeds are green; 6 hours in water, peel off the rice husk, if more than 80% of the swelled is a new rice seed, if more than 50% of the embryo is sunken, it is an old rice seed. In addition, the new rice seed is shiny, green in color and has a clear fragrance The color of old rice seeds is da...

[0002] Old species refer to seeds that have been stored for more than one year after harvest, while new species refer to seeds harvested in the previous season. Due to the different lengths of storage time, there are certain differences in the nutrients consumed, seed vigor, germination rate, and germination potential during the storage period. The seed vigor, germination rate and germination potential of the old species are worse than those of the new species; the rice husk or rice belt of the new seeds has chlorophyll, so a small part of the seeds are green; After 6 hours in water, peel off the rice husk. If more than 80% of the swelled is a new rice seed, if more than 50% of the embryo is sunken, it is an old rice seed. In addition, the new rice seed is shiny, green in color, and has a clear fragrance. ;Old rice seeds are dark in color, yellow in color, and some have a musty smell, but most growers of old rice cannot use them, which seriously increases the cost of growers
