Effects Of Different Fertilizer And Water Management Measures On The Growth And Fructification Of '10-7' Facility Grapes

This text regarded ‘10-7' Grape as the researching material,and designed two kinds of irrigation methods including sprinkling irrigation and flooding irrigation to research their effects on soil bulk density and soil water content.It also designed four kinds of fertilizer and water management to research their influence on ‘10-7' Grape's growth characteristics and fructification characteristics.The results were as follows:1.After one year's tillage management,the bulk density of two irrigation methods didn't have significant difference,but the bulk density of sprinkling irrigation was lower than that of flooding irrigation.2.Given the same irrigation quota,the soil moisture content of sprinkling irrigation was dramatically higher than flooding irrigation from 0~20 cm's layer.However,in the early stage,below the 40 cm's soil layer,the soil moisture content of two methods didn't have marked difference.As time goes,sprinkling irrigation was a little higher than flooding irrigation.As the sprinkling irrigation quota was the half of the flooding irrigation,the moisture content of sprinkling was significantly higher than flooding irrigation in 20 cm's layer,but the result was contrary in 40cm's layer.The soil moisture content can reach 15 % and more all the time,so sprinkling irrigation can save water compared with flooding irrigation.3: Sprinkling irrigation was better than flooding irrigation in grape's growth and fructification,so sprinkling irrigation can replace flooding irrigation.4: Influenced by temperature in different months and grape's growth state,during June to October,water loss rate of soil would be the highest in July,but it would be the lowest after mid October.During these three months,soil moisture quota can maintain at a level that more than 76 % after the next day's irrigation,didn't need watering.5: Before spring germination,compared to applying basic fertilizer in turn,all put on grapes would have a better influence on grape's growth and fructification.In this way,it can satisfy the whole year's need for grape's growth and fructification,andcan save labor cost.
