Embodiment 1

[0020] A cultivation method for maintaining the eating quality of Nanjing 46 rice, comprising the following steps:

[0021] 1) Fine soil preparation, thin water and shallow insertion

[0022] Plow and harrow the field in time after harvesting the front stubble of the field, and plow to a depth of 10-15cm. Before transplanting, apply sufficient base fertilizer, water the field and harrow the field, and remove field residues and weeds at the same time. The quality of the land preparation should be within 3cm. When planting, the field should be solid for 1-2 days to prevent the field from being too rotten, too mushy, and mud gushing to press the seedlings. After the field is leveled, thin water and shallow transplanting are carried out. The field water depth is controlled at 1-3cm, and the shallow transplanting technique of 2-3cm is implemented. The basal fertilizer uses the principle of combining organic fertilizer and inorganic fertilizer.

[0023] 2) Sowing at the right tim...

Embodiment 2

[0032] Adopt the method of embodiment 1, under 5 latitudes of Jiangsu Lianyungang (34.5 °), Huai'an (33.5 °), Yangzhou (32.4 °), Changshu (31.7 °) and Suzhou (31.4 °) respectively set cultivation area. Each pilot set 7 sowing periods: May 10, May 20, May 30, June 9, June 19, June 29 and July 9. The test results are as follows:

[0033] 1) Variance analysis of sowing time and region on the eating quality of Nanjing 46

[0034] There were significant or extremely significant differences in the effects of each eating quality trait between sowing periods and locations. In terms of the interaction effects between sowing dates and locations, except for protein content, the differences were extremely significant (Table 1 ).

Abstract

The invention discloses a culturing method maintaining eating quality of south round-grained nonglutinous No.46 paddy rice. A culturing area is selected at the northern latitude of 31.4 to 32.4 degrees; broadcasting time is May, 10th to May, 30th each year; broadcasting time is advanced with increase of latitude; and nitrogen application rate is 225.0kg / hm<2>. By the use of the culturing method, high yield of the paddy rice No.46 with excellent quality can be ensured and great rice eating quality can be guaranteed; economic benefits of planting excellent rice varieties with eating quality is increased for farmers and higher demands for rice varieties are met for consumers; large-scale plantation and industrialization exploitation can be facilitated; blind application of fertilizers during fertilizer optimization can be reduced; excessive energy waste and environment pollution can be avoided; and the culturing method has great practicality.

Description

technical field [0001] The invention relates to the technical field of rice cultivation, in particular to a cultivation method for maintaining the eating quality of Nanjing 46 rice. Background technique [0002] In recent years, with the improvement of people's living standards and economic conditions, consumers have higher and higher requirements for rice quality, and quality improvement has become one of the important goals of rice breeding. Many studies have shown that the eating quality of rice is not only related to the variety characteristics, but also greatly affected by environmental factors and cultivation conditions, which is the result of the interaction between a polygenic system and environmental factors. [0003] Different ecological rice varieties have different adaptability to different ecological environments, and their rice quality traits will change due to changes in planting regions. Jiangsu Province is one of the main producing areas of japonica rice in...
