Pesticide and fertilizer application method for carya illinoensis through root irrigation, leaf spraying and stem smearing

Abstract

The invention discloses a pesticide and fertilizer application method for carya illinoensis through root irrigation, leaf spraying and stem smearing. The method is characterized by comprising the steps of root irrigation, leaf spraying and stem smearing. The carya illinoensis is subjected to root irrigation operation by using an aqueous solution of paclobutrazol, and a microbial fertilizer is mixed with water and then is irrigated to roots of the carya illinoensis; the carya illinoensis is subjected to leaf spraying by using a growth regulator, potassium dihydrogen phosphate and a nitrogen, phosphorus and potassium compounded fertilizer are sprayed, domestic animal manure is applied as a basal fertilizer, and a controlled-release fertilizer is sprayed to leaves of the carya illinoensis monthly; stems of the carya illinoensis are smeared with a kinetin solution once monthly so as to promote the coarse growth of nursery-grown plants; a fruit tree special fertilizer is applied in a fruit swelling stage, urea is sprayed at a primary stage and later stage of growth, and fertilizer application is carried out on fruiting trees 2 to 3 times every year; and overwintering water and germination water are sufficiently irrigated in winter, timely drainage and waterlogging control are required in a raining period, more water is saved by adopting a bottom infiltrating irrigation technology compared with upside sprinkling irrigation, and the utilization efficiency of moisture is increased.

Description

technical field [0001] The invention relates to the field of planting, in particular to a method for applying medicine and fertilizing to pecan trees with root irrigation, leaf surface spraying and stem smearing. Background technique [0002] Thin-shelled hickory is a plant of the genus Hickory in the family Juglandaceae. It is an ecological and economical tree species integrating high-grade thousand fruits, high-grade woody oil, high-quality hard broadwood and landscaping, and has certain economic, social and ecological benefits. Benefits, broad prospects for development, has developed rapidly in recent years. The propagation of pecan seedlings includes rootstock cultivation and grafting. Pecan has deep roots and is not prone to lateral roots. The traditional field seedling cultivation method has fewer lateral roots and a low survival rate for transplanting. The fertilization and pesticide application of the thin shell hickory tree will also affect the number of fruiting b...

Problems solved by technology

The propagation of pecan seedlings includes rootstock cultivation and grafting. Pecan has deep roots and is not prone to lateral roots. The traditional field seedling cultivation method has fewer lateral roots and a low survival rate for transplanting.

And the fertilization and application of pesticides to the thin-shell hickory tree will also affect the number of fruiting branches and the yield of hickory nuts.
