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 the Test Center of Hubei Academy of Agricultural Sciences, brown rice rate is 81.26%, milled rice rate is 73.03%, head rice rate is 61.17%, rice grain is slender, the ratio of length to width is 3.15%, chalkiness rate is 74%, gelatinization temperature is 4.5 (medium), amylose content is 22.15% (medium), gel consistency is 41.63 mm (medium), protein content is 7.66%, and the comprehensive score is 52. If the ratooning rice is planted, the rice quality is better and the food quality is better.
Cultivation points: closely around the "sparse control weight" cultivation model.
1. Sowing date. Ma Xie 63 has a wide range of adaptation, growing medium rice in most areas of our province and ratooning rice in southeastern Hubei and Jianghan plain. From April 20 to May 10 and ratoon rice from March 25 to the end of March, dry raising seedlings with a seedling age of about 30 days can be used to send two stages of seedlings in the stubble area.
2. Fertilization should be 7.5kg of pure nitrogen per mu, increasing phosphorus and potassium fertilizer, and the proportion of bottom topdressing is 7:3, with special attention to trace fertilizers such as zinc, calcium, silicon and so on.
3. Basic seedling. Ensure about 100000 per mu when transplanting.
4. Reasonable irrigation, especially keeping dry and wet when the seeds are scattered in Goutou. Do not cut off the water too early to ensure that the yellow is ripe until old.
5. Strengthen biological control and enhance the awareness of pollution-free products.

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 the control japonica indica 89, and its 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 in Guangzhou, Shanwei, Zhaoqing and Yunfu showed that the yield per mu was 425kg-450kg in the middle and lower fertility areas, and about 500kg in the middle and upper fertility areas, with the highest yield.
