落蔓栽培是将植物的茎蔓从吊蔓线或吊架上解开、下放,使生长点下落到要求的高度,并随着茎秆的不断伸长定期下落。控制茎秆高度的栽培方法,是蔓生作物延长生长期重要的高产高效栽培措施之一。日光温室落蔓栽培,可保持良好的通风透光性,提高植株上部果实的品质,便于整枝打叉、喷药和叶面追肥等田间操作,同时果实采收也方便。能够确保受光均匀,保持植株相对一致的生长势,促使植株直立生长,保持较大的生长空间,冬季还有利 Drop cultivation is the plant’s stems and stems hanging from the crane line or hanger on the unraveling, decentralization, so that the growth point down to the required height, and with the stem elongation of the regular decline. The method of controlling the height of stalks is one of the important high-yielding and efficient cultivation measures for the growth of vine crops. Sunflower greenhouse cultivation, can maintain good air and light permeability, improve the quality of the upper part of the plant fruit, pruning for pruning, spraying and foliar fertilizer and other field operations, while the fruit harvest is also convenient. To ensure uniform light, maintaining a relatively consistent plant growth potential, to promote plant upright growth and maintain a larger space for growth, winter is also beneficial
