The Research On The Production Performance Of Buckwheat In Dry Land Under Different Sowing Methods

Buckwheat in our country has a long history of planting,is a typical food and medicine homologous crops,deeply loved among people.In Shanxi Province,along the Great Wall,the "trilateral" area of the border,jingbian and dingbian,buckwheat is the region's main crop and dominant crop.In Dingbian area,buckwheat seeding is the traditional sowing method,low yield and poor economic benefit,the production potential of buckwheat can not be embodied,which seriously affects the development of buckwheat in the locality.This paper is through large ridge two rows,Drilling(B1: line 30+15 cm);uniform precision bar.Drill seeding(B2: line 25 cm);Uniform precision Drilling(B3:50 cm),B4: Double ditch seeding,Film cover;artificial ditch.Sowing(B5: line 50 cm);Hole sowing(B6: the line is 40×40 cm),B7: artificial Sowing.seven different ways of sowing.Planting design,studying the water content,dry matter accumulation and agronomic characters of buckwheat soil under different sowing ways.The relationship between yield traits and measured output,and then select the optimum sowing method,provides technical support for high yield cultivation of buckwheat in dryland along the Great Wall.The following results were obtained:The difference in soil moisture content is mainly within the range of 0 to 40 cm underground.In that range,the average moisture content of B2 was 8.7%,followed by B1 for 8.5%.The amount of water in the gutter is 9.7%,followed by B2,which is 9.2%.The difference in moisture content between the furrow was 32.2%.The average moisture content of the B1,B2,B3 and B4 sowing methods was 38.2% higher than the sowing method of B5,B6,and B7.All the way to sow root dry matter accumulation of B4 is significantly higher than the rest of the seeding method;The highest dry matter accumulation of stem B4,B1,B2,B3 and B4 is significantly higher than B1,B2,B3 and B4;Leaf dry matter accumulation of B4 is significantly higher than the rest of the seeding method,B1,B2,B3 and B7 is significantly higher than B5 and B6;Grain dry matter accumulation of B5 and B7 is significantly higher than the rest of the seeding method;The total plant dry matter accumulation in B4 highest 61.974 g,B1,B2 and B3 is higher and more than 50.439 g,B5,B6 and B7 is low and no more than 46.577 g,B6 minimum 36.922 g,B1,B2,B3 and B4 seeding method phase were significantly higher than that of B5 and B6 and B7 seeding method total dry matter accumulation.All sowing methods were high with B2 of 98.7 cm,B2,B1 and B4 significantly higher than the rest.The main stem section has a maximum of 16.6,with B1,B2,B3 and B4 seeding methods significantly higher than B5,B6,and B7 sowing methods.The branches of B4,B1,B2,B3,and B4 were sowed in a significantly higher way than B5,B6 and B7.Plant flowers from B1 of up to 128.9,significantly higher than that of the rest of the seeding method,B4 flowers number per second to B1 is 118.9,significantly higher than that of B2,B3,B5,B6 and B7 seeding method.The agronomic traits of B1,B2,B3 and B4 are all higher than B5,B6,and B7.All sowing methods have a maximum of 3,52.8 grains,B2 and B4 are significantly higher than the rest,B2 and B3 are significantly higher than B5,B6,and B7.Single seed grain weight was 12.3 g with B4,and B1,B2 and B4 seeds were sown significantly higher than the others.The 1000-grain weight is 38.7 g with B5,and B5 and B7 are significantly higher than the rest.The effects of different sowing methods on the yield of buckwheat are larger,the B1 of large ridge and double row(155.3 kg)is the highest,uniform line high precision sowing(B2)is 154.0 kg,and the lowest production of artificial broadcasting sowing is 133.8 kg.Compared with the artificial seeding,the yield of large ridge and the uniform line were more than 16.1%,16%.Groove ridge film covering technology although rainwater harvesting in soil water storage,accumulation of dry matter of buckwheat,buckwheat agronomic traits on performance has a certain advantage,but the film groove ridge covered for buckwheat growth promoting effect only in the early growth,and the way to manual dibbling and thus application still has some difficulty in production;Mechanization of the ditch technology(B1,B2,B3)in dry matter accumulation of rainwater harvesting of soil water,buckwheat,buckwheat agronomic traits and yield and yield traits showed significant advantages.Double the especially big ridge line and 25 cm and precise seeding is worth promoting the application.
