Description

Preparation and application of special compound type growth regulator for beet Technical Field The application relates to the technical field of crop planting, in particular to preparation and application of a special compound growth regulator for beet. Background Beet is an important sugar crop in China, and the economic benefit depends on the yield of tuberous roots and the sugar content. However, in actual production, the yield and sugar accumulation can not reach ideal level due to the problems of reduced photosynthetic efficiency, low transfer efficiency of photosynthetic products to tuberous roots and the like in the late growth period, so that planting income is reduced. At present, although a single plant growth regulator (such as chlormequat chloride and compound sodium nitrophenolate) or a foliar fertilizer is used, the effect is limited or unstable, the traditional cultivation mode generally has the structural contradiction of the ' source ' -warehouse ' relationship, on one hand, improper application of a nitrogenous fertilizer is easy to cause overgrowth of foliar clusters, plants are too high, field is covered, photosynthetic products are wasted, disease risks are increased, namely ' control up ' is insufficient, on the other hand, the existing cultivation technology cannot systematically optimize the transfer and distribution of the photosynthetic products from leaves (sources) to tubers (warehouses), and the tuber expansion power is insufficient, the duration is short, and is expressed as ' promotion down '. In addition, the production increase and the sugar increase are difficult to synchronize, the sugar degree is reduced along with the increase of the yield, the sugar degree can be sacrificed by the measure of increasing the sugar degree, and a comprehensive agricultural scheme for cooperatively realizing the up-control, the down-promotion, the production increase and the sugar extraction is lacked. Therefore, a need exists in the current technology for a compound regulation means capable of systematically regulating the late-medium physiological metabolism of sugar beets, synergistically optimizing the formation, transport and storage of photosynthetic products, and promoting root tuber expansion and sugar accumulation while controlling ineffective growth. The development of a special growth regulator with functions of controlling up and down, increasing yield and extracting sugar has important practical significance for breaking through beet production bottleneck and improving planting benefit.
