Problems solved by technology

This kind of cultivation method is easy to control shoots, not easy to draw winter shoots, flowers come late, flower volume is moderate, fruit setting rate is high, and yield is high. The temperature before and after "Lichun" is low, and the flowering rate is generally not high, which directly affects the yield in the second year, and the risk is relatively high

Embodiment 1

[0017] Embodiment 1 On September 6, 2012, this method was used to cultivate the fruiting mother branches in Dalingshan Feizixiao Litchi Orchard, Qingshanjiao Village, Qingping Town, Lianjiang City, Guangdong Province. At this time, the second shoot length of Feizixiao was about 10 cm, 20ml lychee short flower yield-enhancing element (prepared by the Institute of Plant Protection, Guangdong Academy of Agricultural Sciences) and 20kg water are mixed to make a shoot-killing drug, and the shoot-killing drug is sprayed on new shoots through a spraying machine until the tender leaves are about to Until the water drips, kill the second new shoots, and the third new shoots will be drawn out in late September, strengthen fertilizer and water management and pest control, and cultivate strong and timely fruiting mother branches. The results show that: the fruiting mother branches cultivated by this method are fully mature in mid-November, the crown of the tree has a thick green leaf layer...

Embodiment 2

[0018] Example 2 On August 30, 2012, this method was adopted in the litchi orchard of South Subtropical Crops Research Institute, Zhanjiang City, Guangdong Province to cultivate fruiting mother branches. At this time, the second shoot of Feizixiao was about 5 cm long. Short flower and high yield element (prepared by Plant Protection Research Institute of Guangdong Academy of Agricultural Sciences) is mixed with 25kg of water to make a shoot-killing drug. Spray the shoot-killing drug on new shoots through a spraying machine until the tender leaves are about to drip, and kill the second one. The second new shoot, the third new shoot will be sprouted in mid-September, strengthen fertilizer and water management and pest control, and cultivate strong and timely mother branches. The results show that: the fruiting mother branches cultivated by this method are fully mature in mid-November, the crown of the tree has a thick green leaf layer, and the number of fruiting mother branches i...

Embodiment 3

[0019] Embodiment 3 On August 28, 2013, this method was used to cultivate the fruiting mother branches in Dalingshan Feizixiao Litchi Orchard, Qingshanjiao Village, Qingping Town, Lianjiang City, Guangdong Province. At this time, the second shoot length of Feizixiao was about 5 cm, 20ml lychee short flower yield-enhancing element (prepared by the Institute of Plant Protection, Guangdong Academy of Agricultural Sciences) and 20kg of water are mixed to make a shoot-killing drug, and the shoot-killing drug is sprayed on new shoots through a spraying machine until the tender leaves are about to Kill the second new shoot until the water drips, and the third new shoot will sprout in mid-September, strengthen fertilizer and water management and pest control, and cultivate strong and timely mother branches. The results show that: the fruiting mother branches cultivated by this method are fully mature in mid-November, the crown of the tree has a thick green leaf layer, and the number of...

Abstract

The invention relates to a Feizixiao litchi fruiting cane cultivating method and belongs to the field of application of the litchi production technology. According to the method, retraction pruning is not conducted on Feizixiao litchi with fruits picked, nutrient and water management, insect prevention and sprout protection are well conducted on first grown young sprouts so that the young sprouts can be promoted to grow healthily and mature in time, pesticide spraying and sprout protection are not conducted after young sprouts are grown for the second time, sprout killing chemical is sprayed to kill the sprouts after the sprouts grow to be 5-10 cm long, young sprouts are grown for the third time after about 15 days, and nutrient and water management, insect prevention and sprout protection are well conducted so that the young sprouts can be promoted to grow healthily and mature in time. The Feizixiao litchi fruiting canes cultivated with the method usually fully mature in the middle of November, the leaf layer of a crown is thick, the number of the Feizixiao litchi fruiting canes is large, and a good foundation is laid for high and stable yield of the next year. By the adoption of the method, labor is saved, consumption of fertilizer and pesticide is low, the workload for sprout control is reduced, and the cultivated fruiting canes are high in flowering rate and fruit setting rate.

Description

technical field [0001] The invention relates to a method for cultivating fruiting mother branches, in particular to a method for cultivating fruiting mother branches of feizixiao litchi, which belongs to the field of production and application technology research of litchis. Background technique [0002] my country is the country of origin of lychee and the largest producer in the world. It is mainly distributed in Guangdong, Guangxi, Fujian, Hainan and Taiwan, and its area and output account for 81% and 70% of the world's total respectively. Litchi belongs to one of the pillar industries in the rural industrial structure of various provinces and regions in South China, and it is also one of the most competitive and exportable South Subtropical fruits in China. Feizixiao litchi is an ancient and famous litchi variety in my country, and it is also the main variety in Hainan, Guangdong and other provinces. Feizixiao has excellent quality and flavor, oval fruit, large and smal...
