Shape object, titratable acid and Vitamin C content are without significant difference.It is indicated above that the lemon of infection yellow vein disease is by effectively
The spring tip and the withered summer shoot that is delayed to of bud is promoted to yield positive results after processing, external and interior quality is close with proper tree, nothing
Notable difference.
Treated the fruit endoplasm variation of the strong orchard lemon yellow arteries and veins sick tree of 5 Li Jin of table
In addition, the lemon planting density in Anyue County of Sichuan Province strong orchard Li Jin is about 60 plants/acre, produced according to single plant in 2017
Amount and 5 yuan/kg of orchard lemon unit price, compare the economic benefit of processing group and control group, the results are shown in Table 6.With sick tree control group phase
Compared with BN1, BN2 and BN3 group lemon increase production 350kg, 782kg and 762kg respectively per acre；Remove handle needed for medicament and manually with
And outside annual daily management bagging cost, sick tree control group is low income, and BN1, BN2 and BN3 group are compareed than sick tree per acre
Group increases income 2247 yuan, 4368 yuan and 4127 yuan, respectively 42.3%, 82.3% and the 77.8% of Normal group income respectively.
Therefore, 3 processing groups can effectively reduce the adverse effect of lemon yellow vein disease, can not only effectively reduce yellow vein disease pair
The mortality of tree body injures, and also revolutionizes the status of the low income of yellow vein disease tree, the significant income for increasing farmer, especially
It is the economic benefit highest of BN2 group.
