Early-maturing cultivation method for glutinous rice litchi

Abstract

The invention discloses an early-maturing cultivation method for glutinous rice litchi. The method comprises the following steps: 1) early maturing of last autumn shoots: ensuring that the last autumnshoots are matured in early and middle ten days of October, wherein the thickness reaches 0.5cm or above; spraying a foliar fertilizer prepared from nucleotide, high potassium and high phosphorus for2-3 times for each autumn shoot, and spraying low-concentration ethephon for 1-2 times during the development period of the last autumn shoots; 2) early control of winter shoots: performing spiral girdling to control the winter shoots in early and middle ten days of October; 3) early promotion of flower bud differentiation: performing branch thinning and pruning in middle and late ten days of December, diluting 1000 times of flower regulating elements prepared from cytokinin, Aiduo, auxin and nucleotide, and spraying water in dry weather; and 4) realization of early flowering, early fruitingand early maturing: performing mechanical flower thinning in a flower spike period; after the first batch of male flowers just bloom, performing flower control by uniconazole; spraying a fruit settingelement taking 2.4-D and auxin as main components in a fruit setting period; spraying a foliar fertilizer for protecting and strengthening fruits in middle and late fruit development periods. The mature period of the glutinous rice litchi is advanced to early and middle ten days of June by controlling spikes, thinning flowers, protecting and strengthening fruits, and the yield per mu is 500kg orabove.

Description

technical field [0001] The invention relates to the field of agricultural production, in particular to an early-maturing cultivation method for Nuomi Ci litchi. Background technique [0002] Nuomi Ci is the most high-quality main late-maturing variety in my country. It is mainly distributed in 15 counties and cities including the Pearl River Delta in Guangdong, Qinzhou and Yulin in Guangxi, and the maturity period is mainly concentrated in the middle and late June. According to the survey data of the national litchi and longan industry technology system, in the past three years (2017-2019), the cultivation area of ​​Nuomici lychees has been decreasing, respectively 228,900 mu, 224,900 mu, and 209,700 mu, and the output is very low. The results are obvious, with only 16,300 tons, 80,000 tons, and 14,600 tons respectively. The yield per mu in the big year of 2018 was 355.70 kg / mu, and the yield in the two small years of 2017 and 2019 was only about 70 kg / mu. [0003] How to a...

Problems solved by technology

In order to overcome these inherent shortcomings of Nuomi Ci lychee, a large number of scientific and technological workers have carried out a lot of research, and proposed a set of Nuomi Ci cultivation techniques, including postharvest cultivation of timely and robust mother branches, and the last autumn shoots are fully mature in mid-to-late December. Post-control shoots to promote flowering, comprehensive fruit protection and anti-cracking and other technologies, but after the application of these technologies, it can partly solve the serious problems of glutinous rice cakes that are difficult to flower and fruit drop and crack. , the yield per unit area is still very low, generally lower than 250 kg / mu

Therefore do not solve the problem of precocious and high-yield glutinous rice bran
