In order to give full play to the advantages of the “crystal ball†litchi varieties, appropriate cultivation measures should be taken at the time of cultivation.
First, planting pollination tree "crystal ball" Litchi flowering during fruit setting, if the female flower is not fully pollinated, prone to stunting and no commercial value of small fruit. Therefore, when opening a garden, it is necessary to plant 2-3 varieties with similar flowering duration, such as glutinous rice bran, cinnamon, or Huaizhi, to pollinate the trees, and the proportion should be more than 10%, evenly distributed in the garden.
Second, cultivating the timely and robust results Mother branch "crystal ball" Litchi grows strong, branches less stout shoots, generally after picking the fruit should be mildly retracted pruning, cut to the top of the fruiting branches when the fruit is damaged, or Short, thick and long vegetative shoots promoted the emergence of new shoots and stout shoots. Excellent results Mother tree should reach a new shoot thickness of 0.5 cm or more, with large, thick and shiny leaves.
The last shot of the "crystal ball" litchi (result mother branch) should be taken out before mid-to-late October, and it should be matured in early December to facilitate the formation of flower buds and robust spikes.
Third, do a good job of controlling the tip and promoting flowers and fruit protection actively cultivate late autumn shoots is to prevent the "crystal ball" litchi shoot the best winter tips. By means of various measures such as water control, fertilizer control and pruning, the resulting mother twigs were extracted before and after October 15-25, before the flower buds differentiated, they turned green and mature, and they successfully performed flower bud differentiation, which could solve the problem of manpower caused by the control of the shoots. The waste of resources and the weakening of tree power affect the problems of flower quality and fruit set.
The author believes that generally in the late autumn from late November to mid-December, after the end of the old mature shoot spiral circumcision control tip, can prevent the occurrence of winter shoots, promote the results of the mother branch into flowers. For some early-to-late shoots that were drawn too late, artificial short-cuts can be taken and foliar fertilizers can be applied to promote the young leaves to mature as soon as possible. If individual plants extract winter shoots, shoots can be used to kill shoots.
"Crystal ball" litchi flower head size is relatively moderate, fruit set rate is high, but in the flowering fruit setting period is sensitive to the weather, bad weather will form a small fruit with dysplasia and no commercial value, commonly known as "red jujube fruit."
"Crystal ball" Litchi fruit set is relatively stable, fruit protection during the fruiting period is mainly to prevent pests and disease prevention work. The focus of pest control is Litchi pedis and Litchi chinensis, anthracnose.
At present, the "crystal ball" litchi planting area and yield is very small, and fruit color, fruit shape are very beautiful, and has a certain historical origin and cultural connotation, in product packaging and marketing should be good at "foreign" and "build momentum" , To highlight the personality, characteristics and taste of the "crystal ball" lychees, to use the fruit quality control and "cultural packaging" to establish the high quality and rare fruit value image of the "crystal ball" litchi.
Cultivation Technique of Crystal Ball Litchi
