Best Sowing Date for Wheat Summer Planting in Kunming
نویسندگان
چکیده
[Background] Wheat is the most important food crop, with largest planting area in world. However, production process, due to species degradation and occurrence of new diseases, antigens old varieties are lost, resulting reduced yield even no harvest. In order ensure stable increase wheat, need be updated time. By using different seasons places carry out additional generation breeding two or three generations can bred a year. Accelerate wheat process accelerate rate variety renewal. [Objective] Kunming an ideal place for summer China its special climate. The optimal sowing time Kunming was studied provide guidance double seasons. [Methods] Local spring were used as research materials, components investigated analyzed at four dates. [Results] Agronomic traits data sown lower than that winter whea except nonbearing tillering numbert. highest on June 5. reproductive coefficient, number effective tillers, plant height, spike length, grains per spike, 100 ear grain weight biomass decreased delay date. [Conclusion] Wheat should later 25 obtain more seeds.
