Embodiment 1

[0028] A kind of japonica rice planting method, comprises the following steps:

[0029] (1) plowing and fertilizing the fields;

[0030] (2) planting seedlings to the field at the suitable sowing time;

[0031] (3) Carrying out the field after 4 days of planting;

[0032] (4) Apply urea after 7 days of planting, and perform intermittent irrigation to keep the water depth of the field not less than 1 cm, and the intermittent irrigation lasts for 20 days.

[0033] The present invention has the advantages of fertilizing after plowing and planting respectively, and intermittent irrigation is adopted to increase the rate of panicle formation; the planting specification is smaller, and the mutual influence between seedlings is small, and the yield per mu is higher.

[0034] Specifically, the fertilization in the step (1) is divided into:

[0035] If described seedling is a season of japonica, use ternary compound fertilizer and organic fertilizer, application rate is respectively...

Embodiment 2

[0049] A kind of japonica rice planting method, comprises the following steps:

[0050] (1) plowing and fertilizing the fields;

[0051] (2) planting seedlings to the field at the suitable sowing time;

[0052] (3) Carrying out the field after 4 days of planting;

[0053] (4) Apply urea after 7 days of planting, and perform intermittent irrigation to keep the water depth of the field not less than 1 cm, and the intermittent irrigation lasts for 20 days.

[0054] Specifically, the fertilization in the step (1) is divided into:

[0055] If described seedling is a season of medium japonica, use ternary compound fertilizer and organic fertilizer, application rate is respectively 45kg / mu and 10kg / mu;

[0056] If the seedlings are double-season late japonica, use ternary compound fertilizer, urea and organic fertilizer, and the application rates are 40kg / mu, 5kg / mu and 3kg / mu respectively.

[0057] Specifically, the proportion of nitrogen, phosphorus and potassium in the terna...

Embodiment 3

[0068] A kind of japonica rice planting method, comprises the following steps:

[0069] (1) plowing and fertilizing the fields;

[0070] (2) planting seedlings to the field at the suitable sowing time;

[0071] (3) Carrying out the field after 4 days of planting;

[0072] (4) Apply urea after 7 days of planting, and perform intermittent irrigation to keep the water depth of the field not less than 1 cm, and the intermittent irrigation lasts for 20 days.

[0073] Specifically, the fertilization in the step (1) is divided into:

[0074] If described seedling is a season of medium japonica, use ternary compound fertilizer and organic fertilizer, application rate is respectively 45kg / mu and 10kg / mu;

[0075] If the seedlings are double-season late japonica, use ternary compound fertilizer, urea and organic fertilizer, and the application rates are 40kg / mu, 5kg / mu and 3kg / mu respectively.

[0076] Further, the proportion of nitrogen, phosphorus and potassium in the ternary co...

Abstract

The present invention relates to the technical field of rice cultivation, and particularly relates to a japonica rice planting method. The method comprises the following steps of (1) ploughing a fieldparcel, and performing fertilization; (2) planting rice seedlings to the field parcel in a suitable sowing period, wherein the planting specification is (7-9)*(3-6) inches and the water depth of thefield parcel is 0.5-3 cm; (3) executing field drying after planting of 4 days; and (4) applying urea after planting of 7 days, and executing intermittent irrigation for 15-20 days, wherein the water depth of the field parcel is kept not lower than 1 cm. Fertilizer is applied after ploughing and planting, and intermittent irrigation is adopted, so that the ear bearing tiller rate is increased; andthe planting specification is larger, the influence between the rice seedlings is small, and the yield per mu is higher.

Description

technical field [0001] The invention relates to the technical field of rice cultivation, in particular to a japonica rice cultivation method. Background technique [0002] Japonica rice is a subspecies of rice. It needs short sunshine time, but has a long growth period. It is relatively cold-resistant, has strong stickiness, short and round grains, high protein content and good taste. [0003] Japonica rice is resistant to fertilizer and lodging, and has high water management requirements. It should be planted in plain areas with deep soil, good soil foundation, and convenient drainage and irrigation. At present, in the cultivation of japonica rice, the base fertilizer is only applied once before transplanting, and a certain amount of topdressing fertilizer will be applied according to the actual situation after transplanting. [0004] The existing japonica rice planting methods have poor benefits, and the yield of japonica rice is low, which cannot meet the growing market ...
