Talk about the characteristics and high-yielding cultivation techniques of "Yuyou 6"
Youyou No. 6 is a new combination of high quality rice with super high yield potential. First, the main features 1. The roots are well-developed, the stems are thick, the plant type is compact, the leaves are semi-volume and straight, and the ripening period is smooth. 2, large spikes and more, one branch stem developed. Single-season rice has an average grain number of 300 grains per panicle, up to 600 grains per panicle, and generally yields 650-700 kilograms per mu with a maximum yield of over 800 kilograms per mu. The average grain size of late rice is 180-200 grains per mu, and the average yield per mu is 550-600. Kilograms, up to 650 kg per mu. 3, with partial sensitivity. The mid-early rice in the full-heading period is from late August to early September and late rice is around September 20. 4, high resistance to fertility. In the production, pure nitrogen in acre reaches a maximum of 20.5 kilograms, and there is no leafage phenomenon. 5, strong resilience. Due to thick stems, thick leaf sheaths, well-developed root system, strong resistance to lodging, and strong cold resistance at the heading stage, normal earing in the case of low-temperature cocoa and no neck wrapping. 6. The ability to deliver is greatly influenced by the cultivation measures. The seedlings of long-seeded seedlings are heavy in leaf sheaths and hold a strong grip, which is detrimental to the budding of tillers. Second, the cultivation techniques 1. Childbirth (1) Sowing date: the post-after-season rice in the middle and middle June; the late rice from the end of June to the beginning of July. (2) The amount of acres used: 2 pounds. (3) Putian fertilization amount: Apply 40% Sanyuan Compound Fertilizer 10-12 pounds per mu of Mutian Field, and the entire seedling stage will be high-fertilizer and double-strength (promote long-term delivery), and spray 200mg/L paclobutrazol for two leaves and one heart. (4) Age control: 25 days of medium rice, 20 days of late rice 2. Daejeon Planting Scale After the smoke, rice is 67 inches 2. In the form of hoe planting, the working corridor between hoe and rake is 30cm; the late rice is 66 inches 2. Insert 2 grains of glutinous rice into each bundle. 3, field fertilization level During the whole growth period, pure nitrogen was 15-16 kg/mu, N:P:K=1:0.3:1, and 0.5-1 kg/mu was appropriately increased or decreased depending on paddy fertility. Basal fertilizer 16% ammonium bicarbonate 75-80 kg / mu, 12% calcium over 75-80 kg / mu; 7-10 days after tillage fertilizer application 46% urea 26-28 kg / acre, 60% potassium chloride 40 kg / Mu; panicle fertilizer was applied to 45% of compound fertilizer and 20 kg/mu in the 5th and breakage stages respectively. 4. Pest control Thin strip disease: The prevention and treatment will be conducted once and for all at the end of August and early September of the typhoon. Rice smut disease: Potassium fertilizer is applied to improve the smoothness of the ripening period, and the comprehensive control of rice smut disease has obvious effects. In the 7 days before the break, the break period, heading period, control with Jinggangmycin or Xinkejiasan once. 5, harvesting period: generally 50-55 days after full panicle, until the rice grains at the base of the ear are all yellowed and harvested.
