以下請參照實例詳細說明，然而本發明不受限於這些具體實施例中。 Hereinafter, please refer to the detailed description of the examples, but the invention is not limited to these specific examples.
實例1：本發明提供一種防治雜草的組成物，供作防治雜草的生長，其包含(A)石膏及(B)沙，將該組成物覆蓋於木瓜的作物四周土壤，組成物厚度在10mm，並以灑水頭灑水，以加濕該組成物，並讓組成物自然乾燥後固化，經過1~30天，觀察雜草及作物的生長情形，其中，在覆蓋有組成物的地方，雜草及植物無法生長(參表1)，其中，NO表示雜草無法萌芽及生長，而無覆 蓋組成物的地方，木瓜及雜草生長正常，且澆水時，水分能自然地滲透組成物到土壤中，以供作物所需水分。 Example 1: The present invention provides a composition for controlling weeds for controlling the growth of weeds, which comprises (A) gypsum and (B) sand, and the composition is covered with soil around the crop of papaya, and the thickness of the composition is 10mm, sprinkle water with a sprinkler head to humidify the composition, and let the composition dry naturally and solidify. After 1 to 30 days, observe the growth of weeds and crops, where the composition is covered. Weeds and plants cannot grow (see Table 1), where NO indicates that weeds cannot germinate and grow without overlying Where the composition is covered, papaya and weeds grow normally, and when watering, water can naturally penetrate the composition into the soil to provide the water needed for the crop.
實施例中，(A)對(B)之混合比例為1：1.8~1：0.8，較佳則採用約1：1的比例，以體積比計。水分足夠加濕組成物即可，組成物吸水飽和後，過多的水分會往下滲透到土壤中，因此也無礙組成物中石膏的反應。 In the examples, the mixing ratio of (A) to (B) is 1:1.8 to 1:0.8, preferably in a ratio of about 1:1, in terms of volume ratio. The water is sufficient to humidify the composition. After the composition is saturated with water, too much water will penetrate into the soil, and thus the reaction of the gypsum in the composition is not impeded.
實施例中，該石膏係粉狀，採用無毒性的天然石膏。 In the examples, the gypsum is powdery and non-toxic natural gypsum is used.
實施例中，定義沙的顆粒大小在0.0625~2mm公釐，而顆粒大小在0.004~0.0625公釐的沙則屬於泥的範圍。 In the examples, the particle size of the sand is defined as 0.0625 to 2 mm mm, and the sand having a particle size of 0.004 to 0.0625 mm is in the range of the mud.
實施例中，沙的顆粒在0.0625~2mm公釐時組成物的透水性較佳，而顆粒在0.004~0.0625公釐的沙屬於泥，其顆粒較小，與石膏混合後組成物的透水性較差，而混合前述兩種不同顆粒的沙，則可以調整組成物的透水性，例如混合比例在1：0.1~1：1， 以體積比計，其中，顆粒大的比例多，則透水性佳。而不管用的沙的顆粒大小，對防治雜草的效果都有，差別在透水性的優良否。 In the embodiment, the sand particles have a water permeability of 0.0625 to 2 mm mm, and the particles of 0.004 to 0.0625 mm sand are mud, the particles are small, and the composition has poor water permeability after being mixed with the gypsum. By mixing the sand of the two different particles, the water permeability of the composition can be adjusted, for example, the mixing ratio is 1:0.1 to 1:1. In terms of volume ratio, in which the proportion of the particles is large, the water permeability is good. Regardless of the particle size of the sand used, the effect on weed control is different, and the difference is excellent in water permeability.
另外，實施例中，可以在雜草萌芽前施作，讓雜草無法萌芽，也可以在雜草萌芽後施作，較佳是雜草剛萌芽不久，雜草越長則所需覆蓋的組成物的厚度越大，實施例則是利用組成物將雜草封住，讓雜草死亡。但是，若雜草太高時，則所需的組成物越厚，量則越多，成本相對提高，因此建議在雜草未萌芽或萌芽不久時施作。以上施作都不需要使用到任何化學藥劑。 In addition, in the examples, the weeds can be applied before the germination, so that the weeds can not be germinated, or can be applied after the weeds are germinated, preferably the weeds are just sprouted, and the longer the weeds, the more the composition needs to be covered. The greater the thickness of the object, the example is to use the composition to seal the weeds and let the weeds die. However, if the weeds are too high, the thicker the composition is, the more the amount, and the higher the cost, so it is recommended to apply the weeds when they are not germinated or sprouted. No chemical is required for the above application.
實施例中，在土壤上也撒上豆芽菜的種子，以豆芽菜做為雜草或不要的植物的測試種類，藉助豆芽菜種子萌芽時強勁的穿透力，測試組成物是否能抵擋豆芽菜的萌芽。經過1~30天的觀察，在沒有組成物覆蓋的土壤上，雜草及豆芽菜的萌芽正常，而在有組成物覆蓋住豆芽菜種子的地方，雜草及豆芽菜無法萌芽及成長。 In the examples, the seeds of the bean sprouts are also sprinkled on the soil, and the test species of the bean sprouts as the weeds or the unwanted plants are used, and the strong penetrating power of the bean sprouts seeds is used to test whether the composition can withstand the bean sprouts. The budding. After 1 to 30 days of observation, the weeds and bean sprouts sprouted normally on the soil without the composition, and the weeds and bean sprouts could not germinate and grow in the place where the composition covered the bean sprouts seeds.
實施例中，可以先植栽或播種後再於作物四周舖上實施例中的組成物，也可以舖上各實施例中的組成物後，預留植栽孔位，再予植栽或播種。 In the embodiment, the composition in the embodiment may be planted or planted before planting, or the composition in each embodiment may be laid, and the planting hole position reserved, and then planted or planted. .
實例2：本發明提供一種防治雜草的組成物，供作防治雜草的生長，其包含將(A)石膏及(B)沙的組成物與水混合後覆蓋於木瓜的作物四周土壤，組成物厚度約10mm，並讓組成物自然乾燥後固化，經過1~30天，觀察雜草及作物的生長情形(參表2)， 其中，在覆蓋有組成物的地方，雜草及植物無法生長，而無覆蓋組成物的地方，木瓜及雜草生長正常，且澆水時，水分能自然地滲透組成物到土壤中，以供作物所需水分。 Example 2: The present invention provides a composition for controlling weeds for controlling the growth of weeds, which comprises mixing the composition of (A) gypsum and (B) sand with water and covering the soil around the crop of papaya. The thickness of the material is about 10mm, and the composition is naturally dried and solidified. After 1 to 30 days, we observe the growth of weeds and crops (see Table 2). Among them, where the composition is covered, weeds and plants cannot grow, and where there is no covering composition, papaya and weeds grow normally, and when watering, water can naturally penetrate the composition into the soil for supply. The water needed for the crop.
施作的方式可以採用噴塗機械來噴塗，適合在大面積的施作，也可以採用人工披覆，適合在小面積的施作。至於石膏對沙的比例約在1：1.8~1：0.8，以體積比計，較佳則採用約1：1的比例，而水佔的混合比例為20~45%，較佳為30~35%，以體積比計。如果採用人工披覆，則水的比例可以低一點，若採用機器噴塗方式，則水的比例要高一點。水的理想比例雖然在20~45%，超過該比例時，組成物吸水飽和後，過多的水分會往下滲透到土壤中，因此也不會影響到組成物中石膏的反應。因此，水的比例也可以高於前述的比例。 The method of application can be sprayed by spraying machine, suitable for large-area application or artificial coating, suitable for small area application. The proportion of gypsum to sand is about 1:1.8~1:0.8, and the volume ratio is preferably about 1:1, and the proportion of water is 20~45%, preferably 30~35%. , by volume ratio. If artificial drape is used, the proportion of water can be lower. If the machine is sprayed, the proportion of water is higher. The ideal ratio of water is 20 to 45%. When the ratio exceeds this ratio, the water will be saturated and the excess water will penetrate into the soil, so it will not affect the reaction of the gypsum in the composition. Therefore, the proportion of water can also be higher than the aforementioned ratio.
實施例中，該石膏係粉狀，採用無毒性的天然石膏。 In the examples, the gypsum is powdery and non-toxic natural gypsum is used.
實施例中，定義沙的顆粒大小在0.0625~2mm公釐，而顆粒大小在0.004~0.0625公釐的沙則屬於泥的範圍。 In the examples, the particle size of the sand is defined as 0.0625 to 2 mm mm, and the sand having a particle size of 0.004 to 0.0625 mm is in the range of the mud.
實施例中，沙的顆粒在0.0625~2mm公釐時組成物的透水性較佳，而顆粒在0.004~0.0625公釐的沙屬於泥，其顆粒較小，與石膏混合後組成物的透水性較差，而混合前述兩種不同顆粒的沙，則可以調整組成物的透水性，例如混合比例在1：0.1~1：1，以體積比計，其中，顆粒大的比例多，則透水性佳。而不管用的沙的顆粒大小，對防治雜草的效果都有，差別在透水性的優良否。 In the embodiment, the sand particles have a water permeability of 0.0625 to 2 mm mm, and the particles of 0.004 to 0.0625 mm sand are mud, the particles are small, and the composition has poor water permeability after being mixed with the gypsum. When the sand of the two different particles is mixed, the water permeability of the composition can be adjusted, for example, the mixing ratio is 1:0.1 to 1:1, and the volume ratio is large, wherein the large amount of the particles is large, and the water permeability is good. Regardless of the particle size of the sand used, the effect on weed control is different, and the difference is excellent in water permeability.
另外，實施例中，可以在雜草萌芽前施作，讓雜草無法萌芽，也可以在雜草萌芽後施作，較佳是雜草剛萌芽不久，雜草越長則所需覆蓋的組成物的厚度越大，實施例則是利用組成物將雜草封住，讓雜草死亡。但是，若雜草太高時，則所需的組成物越厚，量則越多，成本相對提高，因此建議在雜草未萌芽或萌芽不久時施作。以上施作都不需要使用到任何化學藥劑。 In addition, in the examples, the weeds can be applied before the germination, so that the weeds can not be germinated, or can be applied after the weeds are germinated, preferably the weeds are just sprouted, and the longer the weeds, the more the composition needs to be covered. The greater the thickness of the object, the example is to use the composition to seal the weeds and let the weeds die. However, if the weeds are too high, the thicker the composition is, the more the amount, and the higher the cost, so it is recommended to apply the weeds when they are not germinated or sprouted. No chemical is required for the above application.
實施例中，在土壤上也撒上豆芽菜的種子，以豆芽菜做為雜草或不要的植物的測試種類，藉助豆芽菜種子萌芽時強勁的穿透力，測試組成物是否能抵擋豆芽菜的萌芽。經過1~30天的觀察，在沒有組成物覆蓋的土壤上，雜草及豆芽菜的萌芽正常，而在有組成物覆蓋住豆芽菜種子的地方，雜草及豆芽菜無法萌芽及成長。 In the examples, the seeds of the bean sprouts are also sprinkled on the soil, and the test species of the bean sprouts as the weeds or the unwanted plants are used, and the strong penetrating power of the bean sprouts seeds is used to test whether the composition can withstand the bean sprouts. The budding. After 1 to 30 days of observation, the weeds and bean sprouts sprouted normally on the soil without the composition, and the weeds and bean sprouts could not germinate and grow in the place where the composition covered the bean sprouts seeds.
實施例中，可以先植栽或播種後再於作物四周舖上實 施例中的組成物，也可以舖上各實施例中的組成物後，預留植栽孔位，再予植栽或播種。 In the embodiment, it can be planted or planted before being planted around the crop. For the composition in the embodiment, the composition in each of the examples may be laid, and the planting hole position is reserved, and then planted or planted.
以上所述，僅為本發明較佳實施例而已，當不能以此限定本發明實施之範圍，即大凡依本發明申請專利範圍及發明說明內容所作之簡單的等效變化與修飾，皆應仍屬本發明專利涵蓋之範圍內。 The above is only the preferred embodiment of the present invention, and the scope of the invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention should still be It is within the scope of the patent of the present invention.
