播期播量对强筋小麦济宁16产量及其构成因素的影响

摘要

不同播期和播种量对强筋小麦济宁16产量及其构成因素有不同的影响.播种量对小麦群体虽有一定调节作用, 但播期影响更大,因此在栽培中一定要做到适期播种.在鲁西南地区, 济宁16适宜播期为10月5～20日, 最佳播期为10月10～15日;适宜播期内播种量以666.7m2基本苗13万～18万为宜,依播期调播量.%Different sowing time and sowing amount had different influences on the yield of high gluten wheat variety Jining 16. Sowing amount had some influence on the yield, but sowing time had greater influence, so it was important for seed to be sown in optimal period. In southwest Shandong Province, the suitable sowing time for Jining 16 should be between October 5th and October 20th, while the best sowing time was between October 10th and October 15th. The optimal number of fundamental seedlings of Jining 16 should be (13 ～ 18 ) × 104 per 666. 7m2 in the suitable sowing period. The sowing amount should be adjusted according to the sowing time.
