培养品种仙人球,一般都用三棱箭作砧木。但三棱箭极不耐寒,到了严寒的冬天,如果没有加温设备,三棱箭往往容易被冻坏。在没有加温条件的家庭如何使三棱箭嫁接的仙人球安全过冬?根据笔者几年的实践,可采取如下措施:要让三棱箭嫁接的仙人球能在室内安全越冬,应在深秋时让三棱箭多晒太阳,在不灼伤三棱箭肉质体的情况下,越晒颜色越深绿,自身体内贮存营养愈丰富;同时适当地施肥,特别注意增施磷、钾肥,使三棱箭机体充实,可增强抗寒能力。进入初冬,对三棱箭要节制浇水,掌握不干透不浇的原则,浇水时不要水过大,浇至土壤微潮即可。避免晚期徒长,三棱箭长出的鲜嫩部分,减弱了冬季的抗寒能力,不利越冬。当气温降至5℃以下时,尽量不要早入室,白天尽量让植株在室外接受阳光照射,晚上承受低温,锻炼其耐寒能力。当气温降低到0℃以下时,放在自制的保温箱内,这种保温箱是根据嫁接盆数的多少,用薄木板或硬纸板制成,上口用铁丝扎成圆拱型,箱内充填棉籽壳或旧棉絮,填至盆沿即止,用塑料膜口袋把整个箱套上,袋口在上,用绳子扎紧,袋内温度过
Prickly pear cultivars, usually with triangular arrow as stock. However, the triangular arrow is extremely hardy, to the cold winter, if there is no heating equipment, triangular arrows are often easily frozen. In the absence of heating conditions, the family how to make three Prism arrow grafted cactus safe winter? According to a few years of practice, the following measures can be taken: to make three Prism arrow grafted immortal ball over the winter in the safe home, Prismatic arrows and more sun, without burns Prismatic arrow flesh mass body case, the more the darker the color darker green, their own body more abundant nutrition; at the same time appropriate fertilization, with particular attention to the application of phosphorus and potash, so that the triangular arrow body Full, can enhance the ability of cold. Into the beginning of winter, the triangular arrow to control the watering, mastery not dry the principle of not watering when watering too large, poured into the soil can be tide. Avoid the late leggy, triangular arrows grow fresh parts, weakened the ability of winter cold, unfavorable wintering. When the temperature dropped below 5 ℃, try not to get into the room as early as possible during the day so that plants receive sunlight, cold at night, exercise their ability to cold. When the temperature dropped to below 0 ℃, on the home-made incubator, this incubator is based on the number of grafting pots, made of thin wood or cardboard, the upper mouth with a wire tie into a round arch, the box Fill the cottonseed shell or old cotton batter, fill it up to the pan, cover the whole case with a plastic film pocket, fasten it with a rope, fasten the bag with temperature
