播期和密度对小果型彩色鲜食高油酸花生农艺性状和产量的影响
Effects of Sowing Date and Planting Density on Agronomic Traits and Yield of Small-Fruit Colored Fresh High-Oleic Peanut
摘要
Abstract
Using small-fruit colored fresh-edible high-oleic peanuts varieties Kainong 615 and Kainong 616 as materials,four different spring sowing dates and five different planting densities were set in Kaifeng,Henan Province.Through plot test in field,the effects of different sowing dates and planting densities on main agronomic traits and yield of them were investigated.The results of sowing date test showed that with the delay of sowing date,the emergence rate gradually increased,both the main stem height and lateral branch length exhibited rising trends,whereas the total number of branches decreased gradually.The number of fruiting branches,the total number of pods and the fresh weight of pods per plant all increased first and then de-creased.The kernel rate and full pod rate gradually increased with the postponement of sowing and harvesting dates.The 100-pod weight and 100-kernel weight varied between cultivars.The density experiments revealed that as the planting density decreased,The main stem height and lateral branch length of both cultivars de-creased;the total number of branches,fruiting branches,total pod number and fresh pod weight per plan all increased gradually;the full pod rate showed a trend of increasing first and then decreased.The yield analysis showed that,the later the sowing date of spring-sown peanuts was,the higher the pod yield was.Under differ-ent density treatments,both of the two varieties achieved the highest pod yield at the density of 103 700 holes per hectare.Considering both agronomic traits and yield performance comprehensively,the optimal sowing time for mulched cultivation of small-fruit colored fresh high-oleic peanuts in northern peanut-producing areas repre-sented by Kaifeng was from April 15th to April 22nd,and the best planting density was 103 700 holes/hm2,which resulted in the highest yield.This conclusion could provide data support and theoretical basis for the ef-ficient cultivation of small-fruit-type colored fresh high-oleic peanut.关键词
