Embodiment 1

[0030] The cultivation of embodiment 1 Yue Nian regenerated rice seed

[0031] (1) Choose a large fertile field with a leeward sun and a water source guarantee, use wild rice with genes for cold resistance and developed root system as the male parent, grow seedlings with plastic film at a temperature above 15°C, and apply sufficient base fertilizer; transplant wild rice when the five leaves are one heart Form a large row with a width of 1.2 meters, one plant per nest, and the distance between rows (withdrawal from the nest) is 7 to 8 inches;

[0032] (2) One month after the wild rice described in step (1) is transplanted, the DS89-1 glutinous rice is used as the female parent, and the plastic film is removed when the seedlings are grown with conventional plastic film to two leaves and one heart;

[0033] (3) When the DS89-1 glutinous rice seedlings grow to five leaves and one heart, they are transplanted between the large rows described in step (1), wherein two small rows of D...

Embodiment 2 1

[0037] Seedling cultivation and planting of rice seed regenerated in one cropping rice area in embodiment 2

[0038] (1) Choose more than 60 mu in Maguan Town, Zhongxian County, Chongqing as the experimental site, and rice will be produced for one season. The regenerated paddy rice seeds cultivated in Example 1 are raised in the middle of March according to the conventional mulch film, and the mulch film is removed when the two leaves are one heart, and the five leaves are transplanted to the field in time, and planted into a wide row of 13 to 17 inches, and a narrow row of 6 to 5 inches. 7 inches, the distance between rows (withdrawing nests) is 6-7 inches, and before transplanting, apply enough base fertilizer to the field, mainly organic fertilizer, and do not apply top dressing;

[0039] (2) It is strictly forbidden to irrigate deep water during the whole growth period, and manage and fertilize according to the routine; rice is fully ripe at the end of August and early Sep...

Embodiment 3

[0045] Seedling cultivation and planting of regenerated paddy rice seeds in the two-cropping rice area of ​​embodiment 3

[0046] (1) More than 80 mu were selected in Chenzhou, Hunan Province as a test site, and rice was produced for two seasons. The regenerated paddy rice seeds cultivated in Example 1 are raised in conventional mulch in mid-February, and the mulch is peeled off when two leaves are in one heart, and they are transplanted to the field in time when the five leaves are planted. inches, the distance between rows (withdrawing nests) is 6-7 inches, and before transplanting, apply sufficient base fertilizer to the field, mainly organic fertilizer, and do not apply topdressing fertilizer;

[0047] (2) It is strictly forbidden to irrigate deep water during the whole growth period, and manage and fertilize according to the routine; at the end of July, the first season of rice is harvested when it is fully ripe, and the rice pile is kept at 18-25cm, and it is managed and...

Abstract

The invention provides a cultivating method of cross-year regrowing rice seeds. According to the cultivating method, wild rice containing cold-resisting and root-flourishing genes is adopted as a male parent, DS89-1 glutinous rice is adopted as a female parent, 3-5 times of recrossing is carried out, and then the cross-year regrowing rice seeds can be obtained. The invention further provides a seedling planting method of the cross-year regrowing rice seeds. Rice which is grown from the cross-year regrowing rice seeds obtained through the cultivating method and is planted according to the seedling planting method has the advantages of being high in yield and milled rice rate, good in rice quality, capable of regrowing in the next year and strong in cold resistance, drought resistance, lodging resistance and Magnaporthe oryzae resistance.

Description

technical field [0001] The invention relates to a method for cultivating and growing seedlings of regenerated rice seeds. Background technique [0002] Rice is one of the most important food crops in the world and is the staple food of more than half of the population in my country. With the continuous increase of the world population, the reduction of the global arable land year by year, the frequent occurrence of natural disasters, and the slowdown of food growth, food security has become a hot issue of general concern to the international community. The existing rice production in my country needs to plow the field every year, sow and plant seedlings every year, which has the disadvantages of high labor intensity, high production cost and low economic benefit. Some agricultural experts once proposed the use of no-tillage method to cultivate rice, but it failed to be fully realized in time. The development of ratooning rice is an inevitable choice for my country to incre...
