Behind the bud
In the Sassafras sandy loam, plant the bud ensuing crop is arranged.Corn and soybean are long respectively in the container of 25Cm diameter.Jowar and seven kinds of ruderal specieses have 4 kinds in each container in the container of two diameter 18cm.Seven kinds of broadleaved herbs are also planted in the container of two diameter 18cm, and one has 4 kinds, and second has 3 kinds.Other additional corn kind in the container of a diameter 18cm.The soil surface of this corn additive vessel is used absorption agent before spraying is handled, perlite is topped, to such an extent as to test medicine can only enter into plant by leaf.Plant has grown 10-21 days, sprays after with the medicament bud that is dissolved in the non-plant toxicity solvent according to its kind.
Before the bud
Plant before kind has bud in executing overplumped Tama silt loam.Those are identical behind these plants and the bud of telling about previously.Except the maize plant with the topped soil surface of perlite, spraying is dissolved in the medicament in the non-toxic solvents when making these plant growings or before planting.
Estimate
Crop and contrast that chemicals treatment is crossed remain on 2-4 week in the greenhouse.Contrast is included, in 0～100 centigrade system scope, visual assessment is reacted in the crop dispenser.Wherein 0 represent not damaged, 100 represent death.Among the table C is the evaluation of crop reaction.
