No. 3 is a hybrid of Waxy Maize from Anhui Province Academy of Agricultural Sciences, which was selected from the line of “Yanyan 10†as the female parent and “Yan 11†as the parent. In 2011, it passed the certification of crop varieties in Anhui Province. The committee approves. The average fresh ear yield of 皖糯3 is 690kg, which is 6.5% higher than the control. The variety has strong stress resistance, wide adaptability, yellow grains, good palatability, and good quality. This variety is suitable for planting in the corn area of ​​Anhui Province and has broad prospects for development and application.
No. 3 emerged and harvested for 70 days. The seedlings were green, and the leaf sheath was lavender. The tip of the first leaf was round to spoon-shaped. The leaves were purple. The plant type was semi-compact, the plant height was 235cm, the ear position was 98°, and the number of adult plants was 20. Slices, tassels branching around 13, purple anthers, colorless filaments, stems supporting roots green. Spike length 18.9 inches, ear thickness 4.1cm, bald tip 1.0cm, ear rows 12-14 lines, hundred position weight 35.2g, ear middle type, cob white, grain pale yellow, fresh fruit ear out of the seed rate of about 65%, The seed rate of dry ears is about 86%.
Cultivation Techniques:
1. Isolate planting: Waxy corn must be planted in isolation to prevent stringing.
2. Fine sowing, to ensure sowing quality: fine soil preparation, shallow enough sowing, fine soil cover species, covering evenly to prevent compaction. Deep sowing 3-5 cm, guaranteed to broadcast a full seedling.
3. Timely early sowing, robbed sowing: general ground temperature stable at 10 ~ 12 °C robbers sowing the most appropriate time. When sowing time, Anhui spring sowing should be at the end of March and early April. If the mulch film coverage can be 7 days to 10 days in advance.
4. Reasonable dense planting: 3 to 4 leaf period seedlings, 5 to 6 leaf stage Dingmiao, about 4000 strains per mu.
5. Chemical weeding: Before sowing, maize was sprayed with 40% atrazine + 50% acetochlor (75 + 75 ml) per mu and closed with 50 kg of water. At the seedling stage, weeds were found and weeding was carried out in combination with cultivators.
6. Scientific fertilization: Reapply base fertilizer, Mushi NPK fertilizer (15-15-15) 40 kg. Early recovery of Miao Fei, 5-6 leaf urea 15 kg urea; supplement Shi ear fertilizer, 10-12 leaf urea 15 kg of urea.
7. Timely drainage and irrigation.
8. Prompt control of pests: Use 2.5% of the enemy to kill 1500-fold liquids at seedling stage to prevent tigers in the ground; use 150-200 ml of Bt emulsion per mu (100 billion spores per gram) during the bell-mouthing period, mix cinders or fine sand. Three to six kilograms of granules are prepared. Each granule is applied to 1-2 grams of granules. The granules are thrown into corn horns to prevent corn mash. It is also possible to use 1.5% phoxim granules in a ratio of 1:10-15. Fine soil mix, about 2 grams per plant, sprinkled into the bell mouth to prevent corn borer.
9. Timely harvesting: The harvest period of waxy corn has great influence on its quality and commodity prices. Harvest time is between 20 days and 25 days after pollination.
Industrial 100Hz LiDAR Solutions
Industrial Laser Distance Sensor of the IT02S & IT03M series are designed for measurements of moving targets.
