Embodiment Construction

[0041] The content of the invention will be further elaborated below in conjunction with the examples.

[0042] In 2009, a test of ladder cultivation of early rice (Lu Liangyou 996) was carried out in Wulong Community, Beisheng Town, Liuyang City 1.0km 2 , in the early rice season production season, that is, in mid-April 2009, urea 161.0kg / hm 2 , potash fertilizer 95.0kg / hm 2 , Phosphate fertilizer 164.0kg / hm 2 , silicon fertilizer 450kg / hm 2 , zinc sulfate 75kg / hm 2 Sprinkle it in the field as a base fertilizer, use a ridging machine to create a ridge, the two sides of the ridge are slopes relative to the horizontal plane, and the angles β and θ between the slope and the horizontal plane are preferably 45° o3 rows of rice seedlings are planted on each side of the ridge, and the direction of the rows is consistent with the extension direction e of the ridge; the shape of the ridge is preferably an isosceles triangle in the A-A section perpendicular to the extension directi...

Abstract

The invention discloses a paddy ladder type cultivation method, belonging to the field of paddy cultivation. The method comprises the following steps: ridging in paddy field sufficiently fertilized with base fertilizer, wherein the opposite horizontal planes at two sides of each ridge are both inclined planes, each inclined plane has an included angle of 30-60 degrees with the horizontal plane, 2-4 rows of paddy seedling are planted at each side of the ridges, and the direction of the row is in accordance with the extending direction e of the ridges; and subsequently cultivating the seedling planted on the ridges until the seedling is ripe and harvested. In the invention, the land utilization area is increased, the total light acceptance area of filed is enlarged; natural water storage is utilized to perform semi-arid irrigation by infiltration, thereby strengthening the permeability of soil, enhancing the temperature of soil, realizing vigorous activity of beneficial microorganisms, increasing available nutrients and coordination water, fertilizer, gas and heat in soil body; the relative humidity of field can be effectively reduced, thereby reducing the occurrence of plant diseases and insect pests; and fertilizers are centralized in ridges, thereby being in favor of the adsorption of root systems and improving the use ratio of fertilizers.

Description

technical field [0001] The invention relates to the field of rice cultivation, in particular to a rice ladder cultivation method. Background technique [0002] At present, more than 95% of the planting area of ​​rice fields in the south adopts flat farming, which is characterized by shallow base fertilizer application, flood irrigation, high field humidity, serious disease and insect pests, long-term soil hypoxia, and easy accumulation of reducing toxic substances. The waste of water resources, the difficulty of pest control, and the soil condition affect the growth of rice and other adverse consequences. With global climate change, precipitation in southern China has undergone significant changes. The total annual rainfall has decreased and the seasonal distribution has been uneven, which has caused great difficulties for rice production. The pursuit of high yield per unit area is still the theme. Although in recent years, breeders have bred many high-yield and high-quali...
