Abstract
The invention provides a planting method in square transplanting mode of paddy rice. Through a technology of carrying out sparse transplanting in a dry nursery and seeding less fine seedlings, older strong seedlings with tillers can be cultivated, the quality and the disease and pest resistance of rice seedlings can be increased, the regreening time can be shortened, and the progress of the farming season can be quickened. By adopting the square transplanting mode to plant, the structure of a rice community is optimized, the living environment of ventilation, illumination, temperature distribution, humidity distribution and the like can be improvement, efficient utilization on light-temperature resources of the paddy rice is realized, high yield, stable yield and sustainable development of the paddy rice are promoted, the social benefit and the economic benefit are increased, the rice planting benefit of farmers is increased, and a good promotion value is obtained.
Description
Technical field
The invention provides the implantation methods of a kind of paddy rice square Planting Patterns, the improvement of existing paddy rice planting method of waiting, comprehensively produces for paddy rice, belongs to agricultural crops production planting technology.
Background technology
At present, traditional dry rice seedling rice seedling is not all with or seldom with tillering, seedling quality is more weak, and speed of turning green after transplanting is slow, and growing process obviously postpones, and easily falls ill, and maturing stage number of productive ear is few.Tradition rice transplanting adopts the Planting Patterns such as rectangle or large-ridge double-row to carry out, due to the difference on Rice Population stereoeffect, affect Rice Population ventilation, printing opacity, temperature and humidity distribution, cause light temperature resource utilization lower, can not develop in harmony between yield component, rice pest is serious, the shortcomings such as output is lower.
Summary of the invention
The object of the invention is open a kind of paddy rice square and plant implantation methods, overcome that traditional seedling quality is poor, resistant to diseases and insects is weak, number of productive ear is few and Rice Population to shortcomings such as the resource utilizations such as light temperature are not high.
Paddy rice square disclosed by the invention plants plant development method, and its technical solution is that dry-raising and sparse-planting essence amount broadcasts the seedling of cultivation above the average age for marriage band tiller less; Concrete operation step comprises:
1. every square metre of plough upper seeding quantity 140-160g, length of time rice seedlings grow 38-42 days, each rice shoot is tillered with 2-3.
2. the arable land described in is the square Planting Patterns that spacing in the rows is equal with line-spacing, and seeding row spacing is 19.9cm-22.3cm, and Planting Densities is every square metre of 20-21 cave, and 4 seedlings are inserted in every cave;
3. cover water seedling-protection in slotting latter 24 hours to promote to turn green;
4. after transplanting, adopt conventional modern scientific management technical method to carry out rice field management.
good effect of the present invention is:significantly improve Seedling Quality in Rice, shorten the rice striking root time, improve rice shoot resistant to diseases and insects, reduce damage by disease and insect to occur, rice shoot band tiller significantly improves the number of productive ear of paddy rice unit are, optimize Rice Population structure, improve the conditions such as Rice Population interior ventilation, printing opacity, temperature and humidity distribution, add the availability of Rice Population to light temperature resource, facilitate rice growth and matter transportation and distribution, coordinate the contradiction between rice yield constituent element, facilitate increasing production of rice.
embodiment:
The present invention is further described by following implementation step, and do not limit the present invention in any way, under the prerequisite not deviating from technical solution of the present invention, any change that those of ordinary skill in the art made for the present invention easily realize or change all will fall within right of the present invention.
embodiment 1
Application rice varieties leads to standing grain 833, tests in academy of agricultural sciences paddy rice institute's Meihekou base, Tonghua, Jilin Province city.Traditional dry rice seedling is changed into " dry-raising and sparse-planting essence amount is broadcast less and cultivated the seedling of above the average age for marriage band tiller " method, namely every square metre of seeding quantity is reduced to 160 g, and the length of time rice seedlings grow is increased to 38 days, and each rice shoot is tillered with 2; By the Planting Patterns of traditional rectangle or large-ridge double-row, change the square Planting Patterns that spacing in the rows is all equal with line-spacing into, seeding row spacing is 22.3cm × 22.3cm, and Planting Densities is every square metre of 20 caves, and 4 seedlings are inserted in every cave; The slotting water seedling-protection that covers immediately for latter 24 hours promotes to turn green; Using the present invention as invention group.If control group 1 is traditional dry rice seedling seeding quantity is 300g/m
2, be not with and tiller, rectangle Planting Patterns, Planting Densities is every square metre of 20 caves, and 4 seedlings are inserted in every cave; Control group 2 is traditional dry rice seedling seeding quantity is 300g/m
2, be not with and tiller, large-ridge double-row Planting Patterns, Planting Densities is every square metre of 20 caves, and 4 seedlings are inserted in every cave.Cave, every community 50 unit of account area number of productive ear is investigated in the annual maturing stage, 5 caves are got, examination grain number per spike, ripening rate, thousand kernel weight Isoquant constituent element, the square Planting Patterns planting effect of examination invention group by average spike number sampling method, experimental period is 3 years, namely repeats for three times.
Under equal conditions, adopt Seedling Quality in Rice of the present invention to significantly improve, damage by disease and insect obviously alleviates, and every hundred strain rice shoot acrial parts and under ground portion dry matter weight increase by 10.1% and 5.9% respectively, and root system number increases by 1.1, and tiller number increases by 0.9; Output per hectare is than traditional Planting Patterns plantation volume increase 7.50%; In yield component, spike number adds 7.55% respectively than conventional Planting Patterns plantation, and ripening rate increases by 6.75%.

embodiment 2
Application rice varieties leads to standing grain 838, tests in academy of agricultural sciences paddy rice institute's Meihekou base, Tonghua, Jilin Province city.Traditional dry rice seedling is changed into " dry-raising and sparse-planting essence amount is broadcast less and cultivated the seedling of above the average age for marriage band tiller " method, namely every square metre of seeding quantity is reduced to 140 g, and the length of time rice seedlings grow is increased to 42 days, and each rice shoot is tillered with 3; By the Planting Patterns of traditional rectangle or large-ridge double-row, change the square Planting Patterns that spacing in the rows is all equal with line-spacing into, seeding row spacing is 19.9cm × 19.9cm, and Planting Densities is every square metre of 21 caves, and 4 seedlings are inserted in every cave; The slotting water seedling-protection that covers immediately for latter 24 hours promotes to turn green; Using the present invention as invention group.If control group 1 is traditional dry rice seedling seeding quantity is 300g/m
