Green source occupies rice
Luyuanzhan is a new variety for both morning and evening, which was bred by Luzhen Zhan 8 and Sanyuan 92 used by the Rice Institute of Guangdong Academy of Agricultural Sciences. In the late provincial regional test (high quality grain group) in 1997, the yield per mu was 375.86 kg, which was 2.93% higher than that of japonica indica 89, and the ripening period was equal to that of japonica indica 89. Retry of provincial and regional examination in 1998. From 1996 to 1997, a small amount of trial planting was conducted in Guangzhou, Shanwei, Zhaoqing and Yunfu. The yield per mu was 425kg-450kg in the middle and lower fertility areas, and about 500kg in the upper and middle fertility areas, with the highest yield reaching 600kg.
The green source accounted for 88.1% of the resistance frequency of group B, 100% of group C and 75.4% of the whole population, which had good field resistance. The resistance to bacterial blight was grade 4. This species has good plant type, plant height 92.6cm, medium tillering ability, stout stem, moderate flag leaf, 20.2cm panicle length, large panicle, and good stress resistance and good ripening color of late rice varieties. This kind of rice has rich genetic basis, wide adaptability, first-class rice quality and good taste and taste.
Main points of cultivation: (1) sparse sowing and raising strong seedlings, the early seedling age is about 30, and the autumn seedling age is 18-20 days. (2) Specification 6X5 (square inch), 3 seedlings per family. (3) moderate re-application of mid-term fertilizer to give full play to the advantages of large panicle and multiple grains. (4) pay attention to the prevention and control of diseases and insect pests.

Ma Xie 63 (Rice)
Variety characters: Maxie 63 was selected by Wuhan University and approved by Hubei crop Variety examination and approval Committee in 1994. The combination is medium-maturing medium indica, the whole growth period is about 140 days, the plant height of medium rice is about 100 cm, the tillering ability is strong, the stem is sturdy, it is more resistant to fertilizer and lodging, good color transformation in the later stage, middle panicle type, and the panicle and seed setting rate are higher. The results of artificial inoculation showed that the number of bacteria and the frequency of toxicity formula were 3 and 28.6 respectively. The rice blast was not resistant to bacterial blight and the yield was about 600 kg. Rice quality: tested by Hubei Academy of Agricultural Sciences

Cultivation techniques of Green Rice
First, select improved varieties and highlight excellent characters. Highlight the characteristics of high-quality varieties, select good stress resistance, strong tillering ability, large spike, suitable for dry breeding in greenhouse, super-sparse planting mode of middle and late-maturing varieties, seed quality above grade II, germination rate more than 95%, purity more than 98%. Germination test was carried out before sowing, and seeds that could not reach the standard could not be made. Second, catch early before snatching and compete for accumulated temperature. Everything should highlight an early word, mainly early raising seedlings and early transplanting rice seedlings. Raise seedlings early in the greenhouse. Sowing and raising seedlings in the first and second accumulated temperate zones in early April, and April in the third and fourth accumulated temperate zones
