Effects Of Sowing With Husk On Yield,Agronomic Traits In Peanut

The main cultivation method of peanuts in China is that two grains per hole and one single grain are finely sown.Compared with single granules,two grains per hole are beneficial to further improve the quality of seedlings,and achieve the purpose of Neat seedlings and Complete seedlings,but both are two holes per hole.The method of granule or single-grain sizing must carry out the process of husk husking.The process of peanut husking is too laborious and laborious,which greatly reduces the production efficiency.The use of peanut shelling machine is common in the cracking of seed kernels after shelling.Open,the emergence rate is significantly reduced,which restricts the development of the peanut industry to a certain extent.In order to further improve the production efficiency of the field,optimize the production method,and explore the necessity of a new seeding method,it is very prominent.The experiment explored the technology of peanut shelling around peanut seeding in an economical,concise and easy-to-operate manner.The pearl bean type variety Nongda hua103 and the large fruit type 414 and the super large fruit type zp01 were used as experimental materials.The best treatment plan for peanut pods was found in the laboratory and orthogonal test and single factor test were used to find out The best embodiment,the best experimental scheme is: peanut pods(complete or incomplete,have been tested to be harmless to the kernels and do not affect normal growth and development)6% cellulase soaked at room temperature for 12 h,rinsed with water sowing.In the Maozhuang Science and Education Park,the shelling sowing test was carried out,and the traditional seed kernels were planted as ck and shelled sowing.The aboveground parts of the peanuts and the roots and soil samples were taken at the seedling stage,the flowering stage,the full fruit stage and the pod-forming stage.Collecting and systematically studying the effects of shell seeding on peanut emergence rate,agronomic traits,chlorophyll content,root growth and development,soil nutrient elements and yield and its influencing factors,and at the same time summarizing the key points of seeding sowing compared with shell seeding Precautions.The main conclusions are as follows:(1)Compared with the control,The yield and emergence rate of shelled sowing can also reach the same level as the control.Under the normal field management,the emergence rate of shelling of three varieties is increased or decreased compared with CK,but the difference is not Reach a significant level.(2)Compared with the control,The stem diameter was significantly greater than that of CK from the seedling stage.The gap persisted with the growth period;the main stem height,side branch length and branch number were almost the same in the seedling stage.From the harvested data,the shelling was better than CK and the plants were more robust.The chlorophyll content of three varieties of shells in the whole growth period was also the same as that of CK.The difference between shelled sowing and CK was not significant.(3)Compared with the control,the root vigor of the three varieties of shelled peanuts was higher than that of CK peanuts from the seedling stage,and then the gap gradually decreased with the growth of the growth period,in which the agricultural flower 103 was in the whole growth period.The root activity of the shelled sowing was higher than that of CK.The root activity of flower 414 and ZP01 in the flowering stage and the full fruiting stage was different but not significant.The total root length of the three varieties was Root diameter,root dry weight,root volume,root-shoot ratio and other indicators showed obvious advantages,compared with the promotion effect of flower 414 and ZP01 shelling.(4)Compared with the control,the nutrients in the three species of shell sown and CK soil decreased significantly during the pod-forming period.Under the condition of shell seeding,the contents of soil alkaline nitrogen,available phosphorus and available potassium were basically maintained in CK.At the same level,the water-soluble calcium content of Nongdahua 103 with shell seeding was significantly greater than that of CK soil from the beginning of flowering period.(5)Compared with the control,the yield of shelling of the three varieties basically reached the same level as that of CK,and the yield of the three varieties had a slight increase.The difference was not significant,and the factors affecting the yield of shelling were basically kept with CK.The same level.(6)Compared with the control,the shell with suitable shell is thin and the distance between the kernel and the shell is small;the shelling is not suitable for deep sowing,and the underground is 3-5cm;the shell is suitable for early maturing.If the seed is planted for two days before sowing,the effect is better.
