Embodiment approach 1

[0019] Dangmentian in a certain place, with an area of ​​1.4 mu, is the first season rice variety Zhongfeng No. 2. On April 28, 2013, the first season of rice was planted. On July 30, it was observed that the grains of the rice spikes were 70% yellow, and 15 kg of urea was applied evenly per acre. In order to prevent the sky from drying out, the water depth of the paddy field was 7-8 inches. Use 4 packs of dimehypo per mu to kill stem borer.

[0020] On August 10, 2013, it was observed that the ear grains of the first season rice were broken. Peel off the stem shells of the rice in the first season, and observe the development and growth of the regenerated buds of the rice in the first season. The regenerated buds are growing well, and there is no need to topdress seedling fertilizer. At this time, due to the large amount of evaporation from the sun in the early stage, the water level in the paddy field dropped to 1 inch. On August 18th, the height of the ratooned rice seed...

Embodiment approach 2

[0022] Dangmentian in a certain place, with an area of ​​1.4 mu, is the first season rice variety Zhongfeng No. 2. On April 25, 2012, the first season of rice was planted. On July 29, it was observed that the grains of the rice ears were 70% yellow, and 11 kg of urea was applied evenly per mu as a seedling fertilizer for rattan rice.

[0023] On August 10, 2012, observed that the ear grains of the first-season rice were broken, peeled off the stalks and shells of the first-season rice, and observed the development and growth of the regenerated buds of the first-season rice. The growth of the regenerated buds was insufficient, and the topdressing fertilizer urea was applied per mu Fat 6 kg. At this time, the water level in the paddy field was 6 inches because the sun was not strong in the early stage and there was not much evaporation. On August 11, the height of the regenerated rice seedlings was observed to be 28-50 cm. Above the field was a piece of golden yellow first-sea...

Abstract

Ten days after the ear grains of the first crop rice are broken, it is the seedling raising period of ratooning rice. On the fourth day after the grains of the first-season rice spikes are broken, the ratooned rice grows into shallow seedlings, and the first-season rice can be harvested. Season rice is harvested two days late, ratooned rice is better than second-tier rice, first-season rice is harvested three days later, ratooned rice is better than third-tier rice, first-season rice is harvested six, seven, eight, nine, ten days late, and ratooned rice is better to the apex. From 1984, when the technology of raising seedlings of ratooning rice was invented, to 1997 when it was successful, the ratooning rice was very good after many years of experimentation. Like the first season rice before 1966, it never failed.

Description

technical field [0001] The invention relates to a rice seedling raising cultivation technique, in particular to a simple cultivation technique of ratooned rice. Background technique [0002] 1. Transplanting ratooning rice is to use the rice pile after harvesting the first season rice, and manage it with water and fertilizer, so that the dormant buds will germinate, grow into rice plants, and the rice heads will mature. The ratooning rice does not need sowing, raising and transplanting rice seedlings, and does not need to plow and harrow the fields. It saves planting, labor, fertilizer, water, and medicine, with less investment and a short growth period. At present, it has been promoted in Sichuan, Fujian, Hubei and other places in my country. Patent No. 200710009602.3 discloses the cultivation technology of ratooned rice with perennial roots, but the technology requires scientific management of water and timely drying of the field; there is also a public technology of tran...
