Embodiment 1

[0026] A planting method of upland rice, comprising the following steps:

[0027] (1) Breeding of upland rice varieties: 1) The male sterile line of "Xiangsi Miao 2" was used as the female parent, and the drought-tolerant restorer line of upland rice was used as the male parent; 2) The male sterile line of "Xiangsi Miao 2" was used as the male parent. The breeding line and the drought-tolerant restorer line of upland rice varieties are hybridized. The planting density ratio of the "Xiangsi Miao 2" male sterile line and the drought-tolerant restorer line of upland rice varieties is 3:2.2, and the hybrid F1 generation is obtained by harvesting the seeds at maturity; 3) by The hybrid F1 generation is the female parent, and the restorer line "Wushan Simiao" is the male parent hybrid. Brassinolide is sprayed when the upland rice is heading and flowering, and the hybrid F2 generation is obtained by harvesting the seeds at the mature stage. The dosage of the brassinosteroid 25 g / mu; ...

Embodiment 2

[0035] A planting method of upland rice, comprising the following steps:

[0036] (1) Breeding of upland rice varieties: 1) The male sterile line of "Xiangsi Miao 2" was used as the female parent, and the drought-tolerant restorer line of upland rice was used as the male parent; 2) The male sterile line of "Xiangsi Miao 2" was used as the male parent. The breeding line and the drought-tolerant restorer line of upland rice varieties are hybridized. The planting density ratio of the "Xiangsi Miao 2" male sterile line and the drought-tolerant restorer line of upland rice varieties is 3:2.5, and the hybrid F1 generation is obtained by harvesting the seeds at maturity; 3) by The hybrid F1 generation is the female parent, and the restorer line "Wushan Simiao" is the male parent hybrid. Brassinolide is sprayed when the upland rice is heading and flowering, and the hybrid F2 generation is obtained by harvesting the seeds at the mature stage. The dosage of the brassinosteroid 30 g / mu; ...

Embodiment 3

[0044] A planting method of upland rice, comprising the following steps:

[0045] (1) Breeding of upland rice varieties: 1) The male sterile line of "Xiangsi Miao 2" was used as the female parent, and the drought-tolerant restorer line of upland rice was used as the male parent; 2) The male sterile line of "Xiangsi Miao 2" was used as the male parent. The breeding line and the drought-tolerant restorer line of upland rice varieties are hybridized. The planting density ratio of the "Xiangsi Miao 2" male sterile line and the drought-tolerant restorer line of upland rice varieties is 3:2.3, and the hybrid F1 generation is obtained by harvesting at maturity; 3) by The hybrid F1 generation is the female parent, and the restorer line "Wushan Simiao" is the male parent hybrid. Brassinolide is sprayed when the upland rice is heading and flowering, and the hybrid F2 generation is obtained by harvesting the seeds at the mature stage. The dosage of the brassinosteroid 28 g / mu; 4) Sow the...

Abstract

The invention relates to a planting method of upland rice. The planting method comprises the following steps: (1) breeding upland rice seeds; (2) preparing block masses; (3) treating the upland rice seeds; (4) hole sowing; (5) performing water management; and (6) managing the fertilizer. According to the planting method of the upland rice, brassinolide is sprayed during the heading and flowering of the upland rice, so that the outcrossing setting percentage can be increased; and the upland rice seeds are scientifically bred, so that the yield of the upland rice is greater than 400 kilograms per Mu, the sprouting rate of the rice seeds is greater than 98 percent, the head rice rate reaches 60 to 65 percent, and the head rice rate is increased by about 10 percent.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a method for planting upland rice. Background technique [0002] Upland rice is also called upland rice. It is an ecological crop formed by the long-term domestication and evolution of rice under dry land conditions without water layer. It is suitable for cultivation in dry land, and can also be planted in paddy fields or depressions. It is mainly distributed in dry lands and hillsides with stable summer rainfall but lack of irrigation conditions, or low-lying areas where spring droughts are prone to waterlogging in summer and autumn. There is a small amount of cultivation in the north and south rice regions of my country. The stems and leaves of upland rice are thick and luxuriant, the leaves are wide, light in color, the root system is developed, the root hairs are many, the osmotic pressure of the roots and the cell juice concentration of the leaves are high, i...
