Fertilizer and method for regulating and controlling flowering phase of jackfruit

Abstract

The invention provides a fertilizer and a method for regulating and controlling the flowering phase of jackfruit. The fertilizer comprises a tree raising fertilizer, rhizosphere spraying liquid and leaf back spraying liquid, the tree raising fertilizer comprises an organic fertilizer and a calcium magnesium phosphate fertilizer in a mass ratio of 30: (0.95-1.05); the organic fertilizer is prepared from 450 to 500 g * kg <-1 > of organic matters, 15 to 16.0 g * kg <-1 > of N, 47.0 to 47.5 g * kg <-1 > of P2O5 and 12.6 to 13.2 g * kg <-1 > of K2O; the rhizosphere spraying liquid comprises a 10 (N)-20 (P2O5)-20 (K2O) high phosphorus and potassium water-soluble compound fertilizer solution; the leaf back spraying liquid is independently selected from a mixed solution of a monopotassium phosphate solution (0.2-0.4 wt%), a boric acid solution (0.1-0.3 wt%) and a chelated calcium solution (0.1-0.3 wt%), wherein the ratio of the monopotassium phosphate solution to the boric acid solution is (0.03-0.06): (0.01-0.03). According to the growth characteristics of the jackfruit, by combining pruning with a customized fertilizer and water management scheme, the flowering period is two months earlier than that of conventional management, and the fruiting period is earlier to June to June.

Description

technical field [0001] The invention belongs to the technical field of methods for regulating flowering of plants, and in particular relates to a fertilizer and a method for regulating the flowering of pineapple honey. Background technique [0002] Jackfruit pulp is rich in nutrition, and it is a characteristic fruit tree widely planted in tropical and subtropical regions of my country. Among them, the planting area in Hainan Province accounts for about 90% of the country. It is an important source of income for local farmers and has a broad market prospect. [0003] At present, there are mainly the following problems in the actual production of jackfruit: first, the supply period of fresh jackfruit is mainly concentrated from May to September, and this period coincides with the period when a large number of fruits are on the market, resulting in a low market price of jackfruit; second, the lack of production period adjustment technology, mainly Relying on empirical fertiliz...
