Embodiment 1

[0020] The purification and rejuvenation method of purple black glutinous rice of the present embodiment comprises the following steps:

[0021] A. Select the seed field: select the field where the purple black glutinous rice was planted in the previous 5 years and no other rice varieties were planted around it as the seed field;

[0022] B. Seed selection: select excellent individual plants from the purple and black glutinous rice, hang them in the sun, thresh them, dry them in the sun for later use, and sow them.

[0023] C. Select seedlings: when the seedlings grow to 48 days, pour water until the water depth reaches the 2nd to 3rd functional leaves of the seedlings;

[0024] D, when the tillers of the seedlings reach 3, transplant to the field and insert a single copy;

[0025] E, reserve seeds: harvest after planting 150 days, select 30 to 40 purple and black glutinous rice seeds on the upper part of the main ear with variety characteristics, large ears and many grains, ...

Embodiment 2

[0027] The purification and rejuvenation method of purple black glutinous rice of the present embodiment comprises the following steps:

[0028] A. Select the seed field: choose the field where the purple black glutinous rice was planted in the previous 3 years and no other rice varieties were planted around it as the seed field;

[0029] B. Seed selection: select excellent individual plants from the purple and black glutinous rice, hang them in the sun, thresh them, dry them in the sun for later use, and sow them.

[0030] C. Select seedlings: when the seedlings grow to 53 days, pour water until the water depth reaches the 2nd to 3rd functional leaves of the seedlings;

[0031] D, when seedling tillering reaches 4, transplant to field, insert single;

[0032] E, reserve seeds: harvest after 145 days of planting, select 30-40 purple and black glutinous rice seeds on the upper part of the main ear with variety characteristics, large ears, many grains, and strong resistance, an...

Embodiment 3

[0034] The purification and rejuvenation method of purple black glutinous rice of the present embodiment comprises the following steps:

[0035] A, select the seed field: select the first 2 all planted purple black glutinous rice, the field that does not plant other rice varieties around as the seed field;

[0036] B. Seed selection: select excellent individual plants from the purple and black glutinous rice, hang them in the sun, thresh them, dry them in the sun for later use, and sow them.

[0037] C. Select seedlings: when the seedlings grow to 60 days, water until the water depth reaches the 2nd to 3rd functional leaves of the seedlings;

[0038] D. When the tillers of the seedlings reach 4, insert a single copy;

[0039] E, reserve seeds: harvest after planting 148 days, select 30-40 purple and black glutinous rice seeds on the upper part of the main ear with variety characteristics, large ears and many grains, and strong resistance, and reserve them as the next generati...

Abstract

The invention discloses a purple-black glutinous rice purification and rejuvenation method, and relates to the technical field of rice purification and rejuvenation. A field for planting purple-black glutinous rice in previous 2-5 years and without other varieties of rice planted around is selected as a seed field, variety degeneration caused by mixing of the other varieties of rice and the variety of the purple-black glutinous rice can be avoided, row spacing is controlled to range from 30*25 centimeters to 30*30 centimeters, watering is performed until water depth reaches a second to third functional leaf when rice seedlings grow to 48-60 days, tillers of the purple-black glutinous rice can be controlled within 6, excessive nutrition growth is inhibited, and reproductive growth of the purple-black glutinous rice is promoted. The purple-black glutinous rice is resistant to lodging, strong in disease resistance, not easy to shatter, large, full and uniform in grain and heavy in rice fragrance, and original production capacity, excellent quality and resistance level of the purple-black glutinous rice can be kept.

Description

technical field [0001] The invention relates to the technical field of purification and rejuvenation of rice, in particular to a method for purification and rejuvenation of purple-black glutinous rice. Background technique [0002] Zihei glutinous rice is a medium-maturing local traditional variety, with a full growth period of 145-150 days, a plant height of 183cm, a relatively compact plant type, wide and thick leaves straight up, the stems and leaves of the plant are dark purple, the kernels are black, and the stems are black. Stronger than lodging resistance, middle-to-high tillering ability, higher ear forming rate, ear length 18.2cm, total grain number per ear 125, average seed setting rate reaches 85.6%, 110-120 grains per ear, 1,000-grain weight 26-27 grams, yield 300-350 kg per mu. In recent years, through selective breeding, as long as the purple black glutinous rice is cultivated properly, the yield per mu can reach 400-450 kg, or even higher. Therefore, at pres...
