Problems solved by technology

Most macadamia nuts bloom in large quantities every year, but only 0-2% of the flowers finally grow into fruits, and more than 98% of the flowers fall off one after another after flowering (early stage) or young fruit development stage (late stage), and excessive flower and fruit drop , not only affect the yield and benefit, but also weaken the tree vigor of the fruit tree itself

Abstract

The invention discloses a flower-promoting and fruit-protecting comprehensive management method for macadamia nuts. The flower-promoting and fruit-protecting comprehensive management method mainly comprises the following steps that paclobutrazol and gibberellin are sprayed in the early stage of flower bud differentiation to control tips and promote flowers, compound sodium nitrophenolate, an amino acid foliar fertilizer, borax and monopotassium phosphate are sprayed in the early flowering stage, compound sodium nitrophenolate, brassin, borax, an amino acid foliar fertilizer and beeswax water are sprayed in the full-bloom stage, and compound fertilizer and amino acid foliar fertilizer are applied in the early fruit setting stage. According to the flower-promoting and fruit-protecting comprehensive management method for the macadamia nuts, bud tillering is promoted, plant cell growth is improved, and the flowering rate and plant resistance are improved by utilizing an exogenous agent in the flower bud differentiation stage of the macadamia nuts, agents capable of promoting the plant growth speed are sprayed in the early flowering stage and the full-bloom stage, flower bud dormancy is broken, and stigma pollination is improved; and meanwhile, beewax water is sprayed, the pollination rate is further improved, so that the pollination, fertilization and fruit setting rate of the macadamia nuts can be effectively improved, and the fruit yield is improved.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a comprehensive management method for promoting flowers and preserving fruits of macadamia nuts. Background technique [0002] Macadamia nuts, also known as macadamia nuts, are rich in nutrition, delicate in taste and excellent in flavor, and enjoy the reputation of "Queen of Dried Fruits". In recent years, with the continuous expansion of macadamia planting area and rapid growth of output value, macadamia planting has been listed as a key industry in the new stage of development and poverty alleviation. [0003] Macadamia nut flowers are racemes, hermaphrodite flowers, stamens ripen first, generally self-pollinating, but have a greater degree of self-sterility. In terms of production, poor pollination and fertilization is recognized as one of the important reasons for the low fruit setting rate and low yield of macadamia nuts, while pollen vigor and stigma recep...
