example 1

[0022] Example 1, the precise and simple cultivation method of wide-adapted super rice:

[0023] Case 1:

[0024] Wide-fit super rice uses 12 kg of N elements, 5 kg of P elements, 12 kg of K elements, and 18 kg of medium and micronutrient elements per mu.

[0025]Spread 10 kg of bensulfuron-methyl and butachlor fertilizer mixture granules with an active ingredient of 0.64% 5 days after seedling throwing or transplanting of the widely suitable super rice to control annual weeds in paddy fields; 6 kg of granules of mixed medicine and fertilizer of thiamethoxam to prevent and control stem borer, rice leaf roller and rice planthopper; 4 kg of mixed medicine and fertilizer granules of difenoconazole and hexaconazole with 10% active ingredients Control rice blast, rice smut, and sheath blight.

[0026] One fertilization and one pesticide application can basically meet the fertilizer requirements of the wide-adapted super rice in the whole growth period and solve the prevention and...

Embodiment 2

[0035] Embodiment 2, the precise, light and simple cultivation method of multi-spike super rice:

[0036] Case 1:

[0037] For multi-spike super rice, 13 kg of N, 5 kg of P, 10 kg of K, and 18 kg of medium and micronutrients are applied per mu.

[0038] Multi-spike super rice 5 days after transplanting or throwing seedlings, sprinkle 10 kg of mefenamide and bensulfuron-methyl fertilizer mixture granules with an active ingredient of 0.2% to control annual weeds in paddy fields; the active ingredient is 4% 6 kg of chlorantraniliprole and thiamethoxam medicine-fertilizer mixture granules to prevent and control the rice borer, rice leaf roller, and rice planthopper; the active ingredients are 2% hexaconazole and carbendazim medicine-fertilizer mixture granules 4 kg can control rice blast, rice smut, and sheath blight.

[0039] One fertilization and one pesticide application can basically meet the fertilizer requirements of the multi-spike super rice in the whole growth period an...

Embodiment 3

[0048] Embodiment 3, the accurate, light and simple cultivation method of big panicle type super rice:

[0049] Case 1:

[0050] The big panicle super rice uses 10 kg of N elements, 5 kg of P elements, 14 kg of K elements, and 18 kg of medium and micronutrient elements per mu.

[0051] Sprinkle 10 kg of quinclorac and bensulfuron-methyl fertilizer mixture granules with an active ingredient of 0.3% 5 days after transplanting or throwing seedlings of the super rice with large spikes to control annual weeds in paddy fields; the active ingredient is 2% 6 kg of chlorpyrifos and pymetrozine mixed drug-fertilizer granules to prevent and control rice borer, rice leaf roller, and rice planthopper; 4 kg of 2% prochloraz and carbendazim drug-fertilizer mixed granules to control rice blast , Rice smut, sheath blight.

[0052] One fertilization and one pesticide application can basically meet the fertilizer requirements of the large spike super rice in the whole growth period and solve t...

Abstract

The invention discloses a method for cultivating super rice accurately, lightly and simply. The method for cultivating the super rice accurately, lightly and simply is characterized by comprising the following steps: step 1, variety characteristics of the super rice are determined and specified as one of wide application type super rice, multi-spike type super rice and large-spike type super rice; step 2, a fertilization technology is determined according to the variety characteristics, determined in the step 1, of the super rice, the demands of different super rice varieties on different nutrient elements and the nutrient fertility condition of local soil; and step 3, a pesticide application technology is determined according to the variety characteristics, determined in the step 1, of the super rice and the incidence rates of the different super rice varieties to pests, weeds and diseases. According to the method for cultivating the super rice accurately, lightly and simply, only one-time fertilization and one-time pesticide application are needed in the whole growing process of the super rice according to the variety characteristics of the different hybrid super rice, the demands of the super rice on fertilizers and the key points of pest and disease prevention, the fertilization requirements of the super rice in the whole growing process can be met basically, the pest and disease prevention problem in the whole growing process can be solved, and therefore labor is saved, the yield is increased, and the method for cultivating the super rice accurately, lightly and simply is safe and environmental friendly.

Description

technical field [0001] The invention relates to the cultivation technology of super rice, in particular to a precise, light and simple cultivation method of super rice. Background technique [0002] Food is the most important thing for the people, and the food issue is always the top priority related to the national economy and the people's livelihood. With the continuous increase of population and the decrease of arable land, increasing food production has become a very urgent issue. [0003] my country's "China Super Rice Breeding Program" began in 1996. On September 18, 2011, the Chinese super rice research team led by Academician Yuan Longping successfully achieved a world record of 926.6 kg per unit area of ​​large-scale planting. Experts said that the current yield of super rice exceeding 900 kg is the result of the combination of improved varieties, good methods, good fields and climate. Good methods include multiple fertilization, precise fertilization, multiple appl...
