1.茎叶处理法
1. stem and leaf treatment method
茎叶处理法是指将除草剂直接喷洒或抹到杂草茎叶上的方法。按施药时期又可分为播种前茎叶处理和苗后茎叶处理。
Stem and leaf treatment is a method of spraying or applying herbicides directly to weed stems and leaves. According to the time of pesticide application, it can be divided into stem and leaf treatment before seeding and stem and leaf treatment after seedling.
(I)播种前茎叶处理
(I) treatment of stem and leaf before sowing
这种方法是在苗圃尚未播种或苗木移植前,用药剂喷洒到已长出的杂草上。要求使用具有广诣性而选择性差、无残留的除草剂。常用的除草剂有百草枯、草甘脚、果尔等。这种施药方法仅能消灭已长出的杂草,对以后的杂草则难以控制。
This method is sprayed on the weeds that have been sprayed before the nursery has been seeded or seeded. It is required to use widely herbicidal, selective and non residue herbicides. Commonly used herbicides are paraquat, grass, foot and fruit. This method of spraying can only wipe out weeds that have grown out, and is difficult to control later weeds.
(2)苗后茎叶处理
(2) treatment of stem and leaf after seedling
苗后茎叶处理是指树木种子萌发出土后施用除草剂的方法。施用时若不采用保护措施,不论杂草和苗木都能接触到药浓。因此,出苗后采用茎叶处理时必须对苗木采取保护措施,如遮盖苗木且喷药后立即用水冲洗苗木等,以防止对苗木造成伤害。对于宽行条播的苗木可采用灭生性除草剂,抗性较强的杂草还可采用灭生性除草刑,用毛笔沾药徐抹单株,进行肪除。
The treatment of stem and leaf after seedling is the method of applying herbicides after germination of trees. No protective measures should be taken, regardless of weeds and seedlings. Therefore, the seedlings must be protected when they are treated with stem and leaf, such as covering the seedlings and rinsing the seedlings with water immediately after spraying, in order to prevent the damage to the seedlings. For the seedlings of wide line sowing, the inactivated herbicide can be used, and the weeds with strong resistance can also be used to eliminate the grass.
2.土缀处理法
2. soil fix treatment
土壤处理法是指采用喷雾、泼浇、撒毒土等方法将除草剂施人土壤t形成一定厚度的药层.接触杂草种子、幼芽,被杂草各部分(如芽鞘)吸收而起杀草作用。土壤处理法一嵌用于防除以种子萌发的杂草或某些多年生杂草,最好在树木种子播种后出苗前处理。此时土壤墒馆好,杂革大量萌发,有利于发挥药效。
The soil treatment method refers to the use of spray, splash, and sprinkled soil to apply the herbicide t to a certain thickness of the soil to form a certain thickness of the drug layer. The soil treatment method is used to control weeds or perennial weeds that germinate seeds. It is best to deal with the seeds before seeding. At this time, the soil moisture content is good, and the germination of mixed leather is beneficial to the efficacy.
(1)常规喷雾法
(1) conventional spray method
使用常规喷雾器将除草剂药液均匀地喷到土壤表面或表层,要求药剂直接接触土壤,药液量根据土壤合水量面定。药液喷洒后不要翻动表土,利用表层毒土杀死茵发的草芽,如施用除草醚、五氯酚钠、西玛津、敌克隆等,也可先均匀喷洒在土壤表层,然后再交叉耙一下表层土壤.使药浓在土层3—5cm处形成药土层,利用除草剂的挥发性杀死刚萌发的杂草。常用的有氯乐灵、杀草通o
Spray the herbicide solution evenly onto the surface or surface of the soil by conventional sprayers, and direct the pesticide to the soil. The amount of the liquid is determined according to the water content of the soil. After spraying the liquid, do not turn the topsoil and kill the grass buds with the surface poison soil, such as the application of herbicide, sodium pentachlorophenol, smatin, and the enemy clone. It can also be sprinkled evenly on the surface of the soil and then cross rake the surface soil. The drug is concentrated in the 3 - 5cm soil layer, and the volatiles are killed by the herbicide. A newly sprouting weed. The commonly used chloral and kills o
(2)泼浇法
(2) spilt casting
泼浇法是指将药剂配成较稀的镕液,装入水壶或水车中搅拌后喷洒在土壤表面,此法适合于粒度较租的可湿性粉剂,但用水量较大,一肢2.3—3.Dkdm2。因使用浓度很小,所以喷洒一定要均匀,否则难以发挥药效。
Spilt casting is a thinner liquid, which is stirred in a water pot or a water truck and sprayed on the surface of the soil. This method is suitable for the wettable powder with a more grain size, but the amount of water is larger, and the limb is 2.3 - 3.Dkdm2. Because the use concentration is very small, so spray must be uniform, otherwise it is difficult to play the efficacy.
