Description
Technical field
The invention belongs to rice cultivating technique field, particularly a kind of cultivation method of lodging resistance in rice.
Background technology
Paddy rice is the first cereal crops of Jurong City, and long-term cultivated area is at 3.11 ten thousand hm
2left and right, due to applying of new varieties and new technology, its output and benefit are enhanced.But due to frequent natural calamity in recent years, every average annual lodging that certain area occurs, have impact on the raising of annual city rice yield and benefit integral level, paddy rice thousand kernel weight is only 19.95g, ripening rate 75.8%, than normal field low 6.45g, 17.7% respectively, part field bottom spike of rice head sprouting.Because of lodging harvesting time receipts more Zao than normal field 7 ~ 10d, increase loss degree further, affect rice quality.
Rice lodging is the result of the comprehensive functions such as breediness, colony, fertilising, cultivation and meteorological condition.It is the immediate cause lodged that cloudy weather for several days running and typhoon pass by, and tree characteristics, agronomic measures, plant capacity for the resistance to lodging and rice lodging have substantial connection.Its reason: one is that basal internode length is partially long.Basal internode is longer, stem wall circularity is poor, and plant lodging resistance is weak.Investigate according to field, lodging field base portion 1,2 internode is obviously longer than normal field, is respectively 3.92cm and 8.77cm, respectively 1.02cm and 2.01cm longer than the field that do not lodge.Basal internode elongates and adds lodging risk.Field is investigated and is also shown the people, and the lodging field overwhelming majority is bending between Section 2, for typical stem falls.Two is that number of productive ear is too much.Investigate according to field, transplanting lodging field average effective fringe is 3,240,000 fringes/h ㎡, 12 ten thousand fringes/h ㎡ higher than normal field.The live field that lodges effective fringe 397.5 fringes/h ㎡, 21 ten thousand fringes/h ㎡ higher than normal live field.Three is that rich water quality management is improper, partially executes early nitrogen fertilizer application.Investigation in 2010 gathers, and lodging field base fetilizer for tillering uses purity nitrogen to account for more than 70% more than the field of 270kg/h ㎡, and due to the prosperous length of the too much paddy rice of nitrogen application during early growth stage, strongly fragrantly to cover, colony is comparatively large, adds the danger of later stage lodging.Long Deep irrigation can make the excessive growth of Culm of Rice internode, simultaneously because of for hypoxgia causes root growth to be obstructed, growing way is undeveloped, it is not dark to take root, very easily lodges once run into wind and rain.Four is the harm of disease worm.Rice sheath blight disease lays particular stress on, rice fulgorid internal injury causes base portion elasticity poor, and stem tissue is destroyed, and stem stalk fracture resistence force declines, and causes lodging.In addition, because of Jurong City September, comparatively violent typhoon occurrence probability is higher than October, and when heading kind typhoon early arrives, grouting time is longer, top-heavy, more easily lodges.Jurong City's late October lodging field 80% occurs in hills, southeast heading comparatively early field.
The impact of lodging on paddy rice: one is plant early ageing, output reduces.After rice lodging, plant is overlapped, and light-receiving area reduces; Simultaneously because ventilative printing opacity is poor, field humidity is comparatively large in addition, and lower blade is withered and yellow rots, and functional leaf area declines.In addition, due to mechanical damage, plant nutrition mass exchange is obstructed, and further enhances the early ageing of root system and blade, affects photosynthesis, and photosensitizing substance reduces, and cause grouting not full, thousand kernel weight declines, and not plump paddy increases, and ripening rate reduces.Two is that meter matter declines.Due to deficiency of being in the milk, the white large percentage of rice trusted subordinate, broken rice rate increases.Spike of rice is in high humidity environment for a long time, and the part grain of rice goes mouldy, germinates, and the glossiness of rice is poor, and quality is produced and heavily declined.Investigation in 2010 gathers, nearly 8 kinds of Jurong City's plantation, with force fortune No. 7, round-grained rice lodging 666.67h ㎡, military fortune round-grained rice No. 15 533.33h ㎡, and military fortune No. 20, round-grained rice lodging 333.33h ㎡.
