A method for judging whether the secondary shoots of the four-season honey awns are in off-season cultivation before the leaf-expanding stage

Abstract

The invention discloses a method for judging whether the secondary shoots of four-season honey awns cultivated against the seasons before the leaf-expanding stage are flowered. The judging time is the early stage of the growth of the secondary shoots after pruning, including the following steps: (1) the color of the leaves; (2) ) the number of leaves; (3) the length change of the leafless branch of the branch; (5) the size of the leaf; (6) the length of the branch; among the above-mentioned 6 indicators, if it reaches the standard ≥ 4, it is considered that the flowering rate of the secondary shoot is high and meets the requirements. Production requirements; if <4, it is considered that the flowering rate of secondary shoots is too low and does not meet the production requirements. The method of the present invention judges whether it is a branch that has completed the differentiation of flower buds, thereby taking remedial measures to promote flowering to win time for flower buds not forming, and can effectively avoid the destructive impact of delaying flowering due to the failure of secondary shoots to flower, thereby avoiding The phenomenon that the fruit is not yet ripe before the arrival of low temperature and rain (December) ensures the flavor and appearance quality of the fruit and improves economic benefits.

Description

Technical field [0001] The present invention relates to a field of fruit tree cultivation technology, particularly to a method of determining whether the secondary shoots of the four seasons of honey cultivation in the opposite seasons are flowers before the leaf spreading period. Background [0002] The anti-seasonal cultivation mode of the four seasons of honey mango is "pruning around April to promote the cultivation of the fruit of the mother branch→ the growth of the fruiting mother branch in May to July→ the flowering and fruit setting → harvesting in October to November" from July to August", and its flowering period is from the end of July to August. The key to the success of the anti-seasonal cultivation of the four seasons of honey is whether it can bloom on time in July and August. After pruning and promoting the shoots in April and the control and flowering promotion measures in June, due to the influence of rain, light, temperature, tree potential and many other fact...

Problems solved by technology

Because if the second shoot fails to flower, it can only promote the third shoot to flower, which may take an extra month or more, resulting in the fruit not being able to mature and go on the market before November, which greatly affects the quality of the fruit ( Because there are many low-temperature and rainy days after December, the leaves cannot perform normal photosynthesis, and the metabolism inside the fruit will also be inhibited), and the commodity price of the fruit will be greatly reduced. The pre-judgment method of whether the shoots are flowering is aimed at ensuring that the second shoots are flowering so as to ensure that the flowering period is in July-August, and gain enough heat and light for the fruit growth after flowering, so that the fruit can be harvested before the low temperature and rain come, and improve the quality of mangoes.
