Introduction of Wheat Variety - Jinmai 70

1. Output In 1998, the average yield was 3007.5kg/hm2, which was 12.6% higher than that of the control Jinmai 53. In 1999, the average output was 2907.0kg/hm2, which was 15.2% higher than the control Jinmai 53. The average output for the two years was 2964.0kg/hm2, which was 13.6% higher than the control, ranking first. In 1999, he participated in the production test of the late-mature winter wheat region in the middle part of Shanxi Province. There were five points at six points to increase production, and the average yield was 2517.0 kg/hm2, which was 6.5% higher than the control Jinmai 53.

2. Characteristics Jinmai 70 has a total of 267 days in the whole growth period and is a strong winter mature variety. After emergence, the coleoptiles are green, the seedlings are robust, the pods are semi-paralyzed, the tillering power is strong, and the spike formation rate is high. After heading, the stems and leaves were covered with waxy wax and the plants were greyish green and half covered. The plants are long-looking, long-lasting, long-lasting leaves, good yellowing, fast filling, uniform ear layers, large panicles and large grains. The plant height is about 75cm, and the stem is tough and resistant. Spike was stick type, long awns, white shells, white granules, hard seeds. Thousand-grain weight 35 to 40g, the number of grains 26 to 30 grains, spikes in the 3.75 million spikes / hm2 or more. Drought-resistant, drought-tolerant, good heat resistance, wide adaptability, large production potential, strong flexibility of storage capacity, increased production in dry years, high yield in high season. Due to its thick stalks, elasticity and strong lodging resistance, it can be planted in general water and fertilizer fields, with a plant height of 85 to 90cm, and can produce higher yields when it is treated with 1 to 2 less water than other varieties. High-yield water-saving wheat new varieties. Heading and ripening was slightly later than Jinmai 53 for 2 to 3 days.

3. Disease resistance The plant protection institute of Shanxi Academy of Agricultural Sciences carried out anti-rust identification. Under the conditions of artificial inoculation, the variety had good resistance to mixed rust rust, and showed lightness on dominant races 30, 31 and leaf rust. In the two consecutive years of the Institute's anti-mite appraisal of Daejeon, the performance was outstanding. The resistance to warts was Grade 1 and it was a type of high resistance.

4. Quality characteristics The quality analysis results of the Grain Quality Supervision, Inspection and Test Center of the Ministry of Agriculture consisted of crude protein (dry basis) 15.15%, wet gluten 33.6%, sedimentation value 35.0 mL, and belonged to noodle and steamed bread special wheat varieties.

5. Ecological Adaptability Jinmai 70 can be planted in late-mature winter wheat areas in central part of Shanxi Province and in dry and medium-fertilized areas in northern winter wheat regions, and can also be planted in drought-fat areas of the east and west mountains of Linfen, Shanxi, Yan'an, Shaanxi, and Tianshui, Gansu. .

6. The sowing date of cultivation techniques is appropriate in late September. Suitable for sowing in dry land 187.5 ~ 225.0kg/hm2, water suitable for sowing 150.0 ~ 187.5kg/hm2, with triadimefon or seed dressing double for seed dressing. Water must be poured over winter water. In early March, wheat fields will be picked up and warmed. After the joints began in mid-to-late April, the spray was applied to dry grass. After the jointing of wheat, ammonium nitrate 225-300kg/hm2 or urea 225kg/hm2 was traced.

Demetdent announced the release of the our company`s wet/dry milling machine. It was added to the Demetdent family of Dental Milling devices in answer to our lab and dental users need for a wet-milling option to handle many of the new brands and materials. The wet/dry milling machine fills a gap in many dental restoration workflows, giving laboratories the added flexibility of milling glass ceramic, composite resin materials that are becoming increasingly popular in the industry due to their high translucency, increased flexural strength and hardness, and overall aesthetic value for inlay/onlays.
