Under Different Interplanting Combination Of Maize And Chili Light Distribution Characteristics And The Impact On Production

This test in the corn chili strip interplanting mode,not peer number ratio as the research object,setting up three planting patterns,corn chili proportion for I1(2:3),I2(2:6),I3(2:9).Corn use grace like 298,chili with gardening,5 tickets are the north main varieties in the region.Through research groups under different planting patterns between light environment and canopy characteristics and production distribution and the related changes,and the utilization rate of light transmittance,light,light interception rate,leaf area index,chlorophyll content,plant height,leaf Angle,to yield and land equivalent ratio of comprehensive evaluation index,it is concluded that in what kind of mode,chili corn belt compound interplanting system to maximize yield and efficiency of land use,and tickets for north region provide certain theoretical technology based on actual production.The results showed that:1.The interplanting mode chili photosynthetic active radiation with the increase of interplanting rows than on the rise trend,corn is similar.This is because with the reduction of corn planting proportion of crops for high to low degree of shade,interplanting groups of photosynthetic active radiation has increased.But for light energy utilization,corn and chili in I2 mode to show the advantages,higher than other planting patterns.2.The corn canopy characteristics between the model's overall performance for I3 mode to effectively promote the growth of the corn,the main reason is that planting density affected,I3 model vane stretch space is enough,plant crops growth restriction factor is less than the other patterns,plant growth is the most exuberant.Chili group on I2 interplanting mode,group the increased amount of light interception is mainly due to the leaf area index,leaf Angle,and the result of plant height with each other.Under the mode of I2 chili largest population leaf area index,leaf Angle and maximum,with appropriate plant height,which makes the light group canopy top more projected onto the chili within groups,therefore I2 mode of chili canopy structure to a more reasonable distribution of received light evenly to each leaf layer within the group,is helpful for chili group to capture of light energy,limited to a certain extent,to satisfy the needs of leaf photosynthesis.At the same time the research shows that the appropriate shade can extend the chili growth period,the hot chili at later growth stage,three kinds of interplanting mode of chilis chlorophyll content were higher than monoculture model,slow down the aging process chili,lengthen the fruit harvest,which laid a foundation for high yield and plant.Overall,I2 mode in canopy characteristics plays a positive role on chili corn yield.3.With the increase of corn chili lines than,the quality of dry matter in has a bigger difference between the groups,the highest corn for monoculture model,chili highest for I2 mode,minimum for I1 mode.This may be because with the increase of corn density,competitive strengthen growth,dry matter accumulation rate was accelerated.From the point of production,corn along with the increase of the planting rows than planting density reduced rapidly,yield per unit of land area is reduced,so the output of each mode respectively the monoculture>I1>I2>I3.The highest yield of chili production for the same,but the processing production of I2>I1,>I3,this is because under the mode of I2,shading sex of chili corn more reasonable,in avoiding chili under strong light point-blank at the same time,again through plenty of photosynthetic active radiation for photosynthesis.So in three kinds of interplanting mode,I1 corn yields the highest under processing,I2 processing of chili production under the highest.Interplanting system output performance for I2>I3>S>I1,and three kinds of interplanting mode of land equivalent ratio of greater than 1,respectively I2(1.35)>I1(1.32)>I3(1.22).This shows that the proper proportion of interplanting configuration,corn-chili strip compound planting system is better than monoculture production advantages.I2 mode makes the corn chili strip interplanting yield advantage to play to the largest,the biggest increase the land utilization,suitable for tickets in north areas of corn chili 2:6 planting patterns.
