Embodiment 1

[0037] Test location: silkworm seed resource base of team 7 of the Institute of Environment and Plant Protection, Chinese Academy of Tropical Agricultural Sciences, Danzhou City, Hainan Province.

[0038] Variety: Jialing No. 106.

[0039] In the present embodiment, the high-efficiency cultivation steps for removing the dormancy of fruit mulberry winter buds in the tropics are as follows:

[0040] Step 1, pruning: in the middle and late December, pruning fruit mulberry branches, subtracting 30% from the top of mulberry fruiting branches (without lignified parts), leaving about 1 meter (90-110cm length) fruiting branches;

[0041] Step 2, clearing the garden: After the pruning is completed, use 5 Baume degrees of lime sulfur to clear the garden;

[0042] Step 3. Watering and moisturizing: before the dormancy treatment, that is, before the germination of the branches, water the whole garden to ensure that the soil is moist;

[0043] Step 4, germination of branches: design thre...

Embodiment 2

[0054]Test location: silkworm seed resource base of team 7 of the Institute of Environment and Plant Protection, Chinese Academy of Tropical Agricultural Sciences, Danzhou City, Hainan Province.

[0055] Variety: White Pearl.

[0056] The cultivation method of this embodiment is different from Example 1 in that step 4, germination of branches: Three treatments are designed for germination, A: clear water+spreading agent control, B: sleep-breaker composition treatment, C: cyanamide+ Spreading agent treatment, in which:

[0057] A: The comparison method of water + spreader is: spray water + 6mL / L spreader;

[0058] B: the treatment method of the sleeping agent composition is: spray 50vol% cyanamide 40 times of liquid+cytokinin (2wt%6-BA) 500 times of liquid+1.8% multiple sodium nitrophenolate water agent 3000 times of liquid+6mL / Spreading agent of L;

[0059] C: Cyanamide + spreading agent The treatment method is: spray 50vol% cyanamide 40 times solution + 6mL / L spreading ag...

Abstract

The invention discloses an efficient cultivation method for breaking dormancy of winter buds of fruit mulberry trees in tropical regions. The method comprises the following steps of: 1, pruning: pruning fruit mulberry branches in mid-to-late December, cutting back the fruit mulberry branches, subtracting non-lignified parts at the tops, and reserving fruit branches with the length of 90-110cm; 2, garden cleaning: after pruning is completed, carrying out garden cleaning with lime sulfur; 3, irrigation and moisture preservation: before branch germination accelerating, watering the whole garden to guarantee soil moisture; 4, branch germination accelerating: spraying a dormancy breaking agent on ungerminated winter buds on the fruit mulberry branches for branch germination accelerating; and 5, after pollination and flowering of the mulberry trees, spraying a nutrient solution to increase the sugar-acid ratio of mulberry fruits. According to the cultivation method, the problems that winter buds of mulberry trees do not germinate or germinate irregularly and the fruit setting rate is low in tropical zones can be remarkably solved, and the yield and quality of mulberry fruits are remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural cultivation, and relates to a dormancy-breaking agent for fruit mulberry and winter buds in tropical areas and a high-efficiency cultivation method for relieving dormancy of fruit and mulberry winter buds in tropical areas. Background technique [0002] Mulberry (Morus alba L) is a perennial woody plant. The medicinal value of mulberry and the edible value of mulberry fruit have gradually attracted attention. Mulberry is listed as one of the third-generation fruits internationally, and the development and utilization of mulberry resources have very broad prospects. On the one hand, after many northern mulberry varieties are introduced to the tropics or subtropics, the germination is incomplete and irregular due to insufficient cold accumulation to break dormancy, some mulberry varieties do not germinate, and the yield is low, which has become a problem for the development of mulberry in tropi...
