Detailed Explanation of High-Quality and High-Yield Cultivation Techniques for Longan
Supplementary nutrients to prevent fruit drop: Longan is in the young fruit growth stage, and the main work is to prevent fruit drop, prevent root rot, and ensure normal fruit growth and development. ① The current rainfall is very favorable for the growth of longan young fruit. In normally managed orchards, the young fruit grows well. Due to the earlier drought, many fertilized...
1. Suitable regions: All longan production areas in Guangdong. The western Guangdong region of our province has the most favorable geographical and climatic conditions for longan cultivation. With higher annual accumulated temperature, especially the rapid warming in spring, and sufficient sunlight, the longan fruit cultivated there matures early, is large, and has good commercial quality.2. Key points of cultivation techniques:
(1) Shaping and pruning of young longan trees. Young trees adopt the pruning method of thinning branches without heading back.
(2) Retraction pruning of densely planted longan orchards. The earlier the retraction pruning is done and the thicker the heading-back and retraction branches, the more conducive it is to flower formation and fruiting the following year, and the branch-thinning retraction method is adopted.
(3) Autumn pruning. Gradually thin out skeletal branches or thicker branches year by year to cultivate timely and effective autumn shoots.
(4) Controlling winter shoots to promote flowering. Regulate the last shoot to mature by the end of November to early December.
(5) Promoting flower panicle formation. Adopt effective technical measures to ensure timely germination and growth of flower buds, so that flower panicles grow and develop normally.
(6) Techniques for strengthening flowers and protecting fruit. Spray "Longan Fruit Strengthening Formula" at the flower bud stage and thin flowers to effectively control flower quantity and improve fruit-setting rate.
