specific Embodiment approach 1

[0149] Embodiment 1: This implementation is that the "rice ridge type plant and hole positioning cultivation method" is carried out according to the following steps:

[0150] 1. Technical regulations for rice ridge-type plant-hole positioning cultivation methods

[0151] The scope of its technical regulations includes: (1) technical regulations for ridge-type plant-hole positioning cultivation methods for early-maturing rice varieties, (2) technical regulations for ridge-type plant-hole positioning cultivation methods for mid-maturing rice varieties, (3) ridge-type plant and hole positioning for late-maturing rice varieties Technical regulations for cultivation methods;

[0152] 2. Rice vegetative body dry-cultivation single-plant hole positioning seedling breeding method

[0153] (1) Take the rice seedling soil for rice seedling soil: protect the ecological environment and do not dig the soil randomly. Every year, take the rice Honda soil before the paddy field is soaked in ...

specific Embodiment approach 2

[0185] Embodiment 2, the difference between this embodiment and Embodiment 1 is: described in step 1, "Riddy ridge type plant and hole positioning cultivation method technical regulations";

[0186] (1) Technical regulations for ridge-type plant-hole positioning cultivation methods for early-maturing rice varieties: in Northeast China, at 45°-46° north latitude, complete the standardized growth period operations of the technical regulations for ridge-type plant-hole positioning cultivation methods for early-maturing rice varieties within the specified time. The following steps are performed;

[0187] Rice vegetative body dry-cultivation single-plant hole positioning seedling method: the seedling period of early-maturing rice varieties is 69 days in total. Variety, soaking, germination, sowing, seedling area 10m 2 ~10.25m 2 41 trays of seedlings are required, "the seedling stage of the rice seedling stage" is from March 30 to April 18, 20d, the rice standing needles emerge to...

specific Embodiment approach 3

[0198] Specific embodiment 3: The difference between this embodiment and one of specific embodiments 1 to 2 is: in (5) described in step 2, "rice seedling vegetative structure": the best embodiment of this invention is : 1. Rice seedling vegetative body of early maturing varieties: the diameter of the upper flat circle of the conical shape is 4.7cm~4.8cm, the height of the conical vegetative body is 6cm~8cm, the diameter of the bottom circle of the conical vegetative body is 2cm~2.6cm, 1m 3 The soil can grow seedlings of 2.8 to 3.5 mu. ② The vegetative body of medium-ripening rice varieties: the diameter of the upper flat circle of the conical shape is 5.8 cm to 6 cm, the height of the conical vegetative body is 6 cm to 8 cm, and the diameter of the bottom circle of the conical vegetative body is 2 cm to 2.6 cm. 1m 3 The soil can grow seedlings of 3 to 3.5 mu. ③ The vegetative body of late-maturing rice varieties: the diameter of the upper flat circle of the conical shape is 6...

Abstract

The invention discloses a rice ridge-type plant hole locating cultivation method, and relates to rice cultivation methods. The rice ridge-type plant hole locating cultivation method solves the technical problem that existing rice cultivation is low in acre yield. The rice ridge-type plant hole locating cultivation method is the achievement of photosynthetic physical study and photosynthetic chemical application study of rice growing photosynthetic efficiency, and the luminous energy photosynthetic efficiency per square hectometer of rice reaches 0.7%-1.5% when calculated according to economic yield. A rice vegetative body draught seedling single plant hole locating seedling method is adopted in seedling, the rice early-maturing variety and the rice medium-maturing variety realize secondary tillering, and the rice late-maturing variety realizes tertiary tillering. The rice ridge-type plant hole locating cultivation method is adopted in a parent rice field, rice reaches 100% tillering rate of 100% tillering capacity, the early-maturing variety realizes quaternary tillering, the medium-maturing variety realizes quinary tillering and the late-maturing variety reaches senary tillering. Tillering plant numbers are controlled, and the vegetative period transforms to the early stage of the reproductive period, so that young ears differentiate to breed large ears. The increase yield range per mu of the rice of early-maturing variety is 700kg-1300kg, the increase yield range per mu of the rice of medium-maturing variety is 800kg-1400kg and the increase yield range per mu of the rice of late-maturing variety is 900kg-1500kg.

Description

Technical field [0001] The present invention relates to a method of rice cultivation. Background technique [0002] Currently known existing rice transplanting cultivation methods [0003] At present, it is known that the existing rice transplanting cultivation method: refers to the use of plastic greenhouses to raise rice seedlings for 30d to 40d in early April in spring. The cultivation technique of transplanting seedlings in the greenhouse to the rice Honda. It is called, "Currently known methods of rice transplanting and cultivation". [0004] The rice area in Heilongjiang Province in the northeast is the northernmost rice area in China, with a latitude of 45°-46° north. The growth period of rice Honda is 115~130d, and the annual accumulated temperature is 2600℃~2800℃. During the growing period of rice Honda, "only early-maturing varieties can be cultivated". Northeast cold current chilling injury, low temperature and early frost have always been one of the yield fa...
