Multiple cropping mode for improving benefits of lychee orchard in South China and ecologically restoring soil

Abstract

The invention discloses a multiple cropping mode for improving benefits of a lychee orchard in the south China and ecologically restoring soil. The crop intercropping mode of Feizixiao lychee and leguminous crops comprise the following steps: carrying out farrowing in a middle passage, filling fallen leaves, spraying cold-proof and anti-freezing agricultural input products, applying liquid fertilizer, spraying a biological decomposition agent and planting leguminous crops. The crop intercropping mode of the Feizixiao lychee and the leguminous crops mainly comprises the steps of carrying out furrowing in the lychee passage, filling fallen leaves, spraying the decomposition agent and planting the leguminous crops. According to the multiple cropping mode of the Feizixiao lychee and the leguminous crops, the utilization rate is increased by applying the liquid fertilizer; the biological decomposition agent is sprayed to accelerate decomposition of fallen leaves; and the cold-proof and anti-freezing agricultural input products are sprayed to improve the low-temperature resistance and the flower and fruit setting rate of the litchis, land-nourishing crops, leguminous crops, litchis fallen leaves and straw returning are planted to jointly supplement a biological carbon source and a nitrogen source for soil so as to restore the soil fertility, and synchronous improvement of the yield and the quality of the lychee and sustainable utilization of cultivated land in the lychee orchard are achieved.

Description

technical field [0001] The invention relates to the technical field of fruit tree cultivation, in particular to a multiple cropping mode for improving the benefit of litchi orchards in South China and restoring soil ecology. Background technique [0002] The poem "eat three hundred lychees a day, and never give up to be a Lingnan native" is not unfamiliar to us. From the verses, we can know that lychees also had a very important position in the hearts of the ancients. Seriously affected the growth and development of litchi and the formation of yield and quality. Litchi tree likes high temperature and high humidity, and likes to be sunny. Litchi in my country is mainly planted in Guangdong, Fujian, and Guangxi. Litchi is known as one of the "four major fruits in southern China". Litchi tastes sweet and sour, warm in nature, and enters the heart, spleen and liver meridian; it is a good food therapy product for those with intractable hiccups and diarrhea at dawn. more attenti...
