锦橙是四川柑桔的主要推广良种。近年来四川新栽的几十万亩锦橙幼树已陆续试花结果,但普遍存在开花多而着果少的问题。如何提高着果率,是夺取锦橙幼树早结丰产的关键问题之一。关于柑桔保果技术,国内外曾进行过许多试验,提出了不少提高柑桔着果率的农业技术措施。如加强肥水管理,培养健壮的树势;培养健壮的结果母枝和优质的花朵,花期摇花;花期喷硼;花期利用蜜蜂传粉或人工授粉;花后喷生长素2,4-D或赤霉素,花后环割主枝;控夏梢;叶面喷布磷酸二氢钾等等。但过去的保果技术试验多系单项技术的比较试验。由于影响柑桔落花落果的
Jincheng orange is the main promotion of Sichuan citrus varieties. In recent years, the newly planted hundreds of thousands of acres of young trees in Sichuan have been tested flower results, but the prevalence of flowering and fruit less problems. How to improve the fruit rate is one of the key issues to seize the early yield of Jinchu saplings. On the citrus fruit preservation technology, many experiments have been conducted at home and abroad, put forward a lot of agricultural technology measures to improve the fruit rate of citrus. Such as strengthening the management of fertilizer and water, cultivating robust tree vigor; cultivating robust parent and high-quality flowers, flowering flowers; spraying boron during flowering; using bee pollination or artificial pollination during flowering; spraying auxin 2,4-D or red Mycin, after flowering cut the main branch; control summer shoots; foliar spray potassium dihydrogen phosphate and so on. However, in the past, many test techniques were compared with individual techniques. Due to the impact of the fall and fall of citrus fruit
