Description
Technical Field
The invention belongs to the technical field of rice cultivation, and particularly relates to an indica-japonica rice intercropping high-yield planting method.
Background
Rice is one of the important grain crops in China, and the increase of the yield of the rice is always the key point of research work. High-yield cultivation of rice is a complex comprehensive technical system, and relates to factors such as the environment of a planting area, variety selection, cultivation measures and the like. Different rice growing areas have different methods for increasing yield due to different environments. In recent years, in view of the advantages of short growing period, high yield, high quality, seed saving, water saving, labor saving, income increasing and the like of the regenerated rice, the time and the space can be intensively utilized, and the large-area popularization and planting can be carried out in areas with insufficient temperature and light resources and surplus season. The regenerated rice must be planted in the area with proper temperature and light conditions, so that stable and high yield can be ensured. However, in some areas, due to the limitation of temperature and light resources, such as the northern area of the rice growing area in the middle and lower reaches of Yangtze river, the cultivation of the regenerated rice cannot be promoted. Therefore, a new high-yield planting mode suitable for large-area popularization is explored, and the method has important significance for high and stable yield of rice.
Disclosure of Invention
The invention aims to provide a high-yield planting method for indica rice and japonica rice intercropping, which can effectively improve the yield of rice.
In order to achieve the purpose, the invention adopts the technical scheme that:
an indica-japonica rice intercropping high-yield planting method specifically comprises the following steps: indica rice and japonica rice are intercropped, the indica rice is transplanted, the japonica rice is planted in a direct seeding mode when the indica rice is transplanted, the indica rice reaches the full-ripe stage firstly, the indica rice is harvested, and then the japonica rice is harvested after the japonica rice reaches the full-ripe stage.
In the intercropping rice planting method, indica rice is planted in a transplanting mode, japonica rice is planted in a direct seeding mode, and the two types of rice are intercropped. Due to different planting modes, the plants of indica rice are higher than those of japonica rice in the growing process, and japonica rice continues to grow to the full-ripe stage after the indica rice is ripe and harvested. The rice planting method of the invention fully utilizes the temperature and light resources and maximizes the marginal effect, thereby improving the yield of rice. In the rice intercropping planting method, the indica type rice is matured after the japonica type rice is matured, and the japonica type rice intercropping planting method is suitable for areas with insufficient temperature and light resources due to cold resistance of the japonica type rice, and can be popularized and utilized in a large area. When the planting method is adopted to plant rice, the indica rice seedlings can be transplanted and the japonica rice seeds can be directly sown at the same time in an artificial mode.
Preferably, the seedling age of the seedlings is 25-40 days when the indica rice is transplanted.
When the planting method is adopted to plant rice, the planting time of indica rice and japonica rice is reasonably adjusted according to the planting area, and the two kinds of rice need to be completely mature. For Xinyang and the like in Chinese areas such as Henan province, it is preferable for climatic reasons that indica rice is transplanted in spring rice form.
When the planting method is adopted to plant rice, the planting varieties of indica rice and japonica rice can be selected from the existing varieties. Preferably, the indica rice variety is any one of the super-excellent thousand, the Y-excellent 1 and the Y-excellent 2. The japonica rice is any one of Yongyou No. 9, New Rice No. 6 and Xinjing 1787.
When the planting method is adopted for rice planting, the treatment of the seeds of japonica rice is carried out according to the treatment method of the seeds in the existing rice direct seeding technology.
When the planting method is adopted for rice planting, the intercropping mode of indica rice and japonica rice, such as row ratio, row spacing, planting distance and the like, can be adjusted according to actual conditions.
Preferably, the row ratio of indica rice to japonica rice in intercropping is (1-3): (1-3). Further preferably, the row ratio of indica rice to japonica rice is 2:2, i.e. 2 rows of japonica rice are intercropped in every 2 rows of indica rice.
Preferably, the row spacing during intercropping is 20-30 cm, namely the distance between the rows of indica rice, between the rows of japonica rice and between the rows of indica rice and between the rows of japonica rice is 20-30 cm. More preferably, the line spacing is 25 cm.
In the intercropping process, the distance between strains of indica rice and the distance between strains of japonica rice are equal. Preferably, the spacing between the indica rice plants is 10-20 cm. The plant spacing of japonica rice is 10-15 cm.
When the planting method is adopted for rice planting, field management is reasonably adjusted according to the soil condition and insect pest condition of a planting field.
Detailed Description
The present invention will be further described with reference to the following specific examples.
Example 1
The indica-japonica rice intercropping high-yield planting method comprises the following steps:
planting: when the seedlings of super-fine thousand-rice (indica rice) are transplanted, seeds of super-fine thousand-rice (japonica rice) are planted at the same time, the direct seeding and excellent rice 9 (japonica rice) is planted at the same time, the intercropping row ratio of the indica rice to the japonica rice is 2:2, and the row spacing is 25 cm. The planting distance of the indica rice seedlings is 13.3cm, the spacing of the japonica rice seeds is 10cm, and the indica rice and the japonica rice are respectively harvested in the full-ripe period;
field management: in the planting process, 20.0kg of pure nitrogen is applied to each mu in a total ratio of N to P2O5∶K2O (mass ratio) ═ 2: 1: 2. the mass of the applied nitrogen, phosphorus and potassium is pure nitrogen and P respectively2O5And K2Measuring O, wherein the mass ratio of the nitrogen fertilizer to the base fertilizer, the tillering fertilizer and the panicle fertilizer is 4: 2: 4, the base fertilizer is completely applied 1 day before the transplanting of the indica rice, and the tillering fertilizer is completely applied 7 days after the transplanting of the indica rice; applying 60% of spike fertilizer to four fallen leaves of indica rice and 40% of spike fertilizer to four fallen leaves of japonica rice; enough phosphate fertilizer is applied in the base fertilizer at one time; the potash fertilizer is applied to 50% of base fertilizer, 50% of inverted four-leaf fertilizer of indica rice, and other management is the same as that of common high-yield field.
