Method for judging whether secondary shoots of perennial honey-mango tree cultivated in out-of-season manner bloom before leaf-unfolding stage

A technology of four-season honey awn and leaf-expanding period, which is applied in cultivation, application, agriculture, etc., can solve the problems of lower fruit commodity prices, one month or more time spent, and affect fruit quality, so as to ensure the flavor and quality of the fruit. The effect of improving the appearance quality and improving economic benefits

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 even more time, 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 inside of the fruit will also produce metabolic inhibition), and then 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.

Embodiment 1

[0020] In August 2016, we used the method of the present invention to judge the flowering of secondary shoots cultivated in the off-season in the 100 mu of Four Seasons Honey mango orchard planted in the Agricultural Science Institute of Nanning Overseas Chinese Investment Zone. The orchard was planted on March 15, 2010. The distance between plants is 4.0m×2.5m, and there are 66 plants per mu.

[0021] Specifically, the method of judging whether the secondary shoots of four-season honey awns cultivated against the season before the leaf spreading period is the early stage of the growth of the secondary shoots after pruning, that is, when the branches are in the middle of elongation and the leaves are at the end of stretching. as follows:

[0022] (1) The color of the leaves: if the secondary shoots of Sijimimang are not differentiated into flower buds, they will be purple or red during the period from the leaves to the leaves when they are drawn; if they are flowering branches...

Embodiment 2

[0032] In August 2019, we used the method of the present invention on the 30-acre Four Seasons Honey mango orchard planted in Nanyang Town, Qingxiu District, Nanning City, in the "Huayu Lake Agricultural Eco-tourism Zone" to judge the flowering of secondary shoots cultivated in off-season. On April 15, 2014, the distance between rows and plants was 4.0m×3.0m, and 55 plants were planted per mu.

[0033] Specifically, the method of judging whether the secondary shoots of four-season honey awns cultivated against the season before the leaf spreading period is the early stage of the growth of the secondary shoots after pruning, that is, when the branches are in the middle of elongation and the leaves are at the end of stretching. as follows:

[0034] (1) The color of the leaves: if the secondary shoots of Sijimimang are not differentiated into flower buds, they will be purple or red during the period from the leaves to the leaves when they are drawn; if they are flowering branches...

Embodiment 3

[0044] In August 2019, we used the method of the present invention to judge the flowering of secondary shoots in the off-season cultivation of a 100-acre Sijimi mango orchard planted in Wanjia Village, Xiangxian Town, Shanglin County, Nanning City. The orchard was planted on March 13, 2014. Every day, the distance between rows and plants is 4.0m×3.0m, and 55 plants are planted per mu.

[0045] Specifically, it is a method of judging whether the secondary shoots of four-season honey awns cultivated against the seasons before the leaf-expanding period are flowering. The judging time is the early stage of the secondary shoot growth after pruning, that is, when the branches start from the elongation period to the end of the leaf extension period. as follows:

[0046] (1) The color of the leaves: if the secondary shoots of Sijimimang are not differentiated into flower buds, they will be purple or red during the period from the leaves to the leaves when they are drawn; if they are f...

Abstract

The invention discloses a method for judging whether secondary shoots of a perennial honey-mango tree cultivated in out-of-season manner bloom before a leaf-unfolding stage. The judging time is an earlier stage of growth of trimmed secondary shoots. The method comprises the following operation steps: (1) detecting colors of leaves; (2) detecting the number of the leaves; (3) detecting the length change of non-leaf sections of twigs; (4) detecting gestures of the leaves; (5) detecting the sizes of the leaves; (6) detecting the lengths of the twigs; judging that the blooming rate of the secondary shoots is high and meets production requirements when the number of indexes reaching the standard in the six indexes is more than or equal to 4; and judging that the blooming rate of the secondary shoots is too low and does not meet the production requirements when the number of indexes reaching the standard in the six indexes is less than 4. The method disclosed by the invention can be used forjudging whether the secondary shoots are twigs finishing flower bud differentiation, and the time for promoting blooming by utilizing remediation measures when the secondary shoots do not bloom is gained, so that the frustrating influence caused due to delaying of a flowering stage because the secondary shoots do not bloom can be effectively avoided, the phenomenon that fruits do not mature before low-temperature overcast and rainy weathers (December) come is avoided, the flavor and appearance quality of fruits are guaranteed, and the economic benefit is increased.

Description

technical field [0001] The invention relates to the technical field of fruit tree cultivation, in particular to a method for judging whether the secondary shoots cultivated in four seasons and out of seasons are flowering before the leaf spreading stage. Background technique [0002] The off-season cultivation mode of Four Seasons Mimang is "Pruning around April to promote shoots and cultivate the fruiting mother branch→May-July fruiting mother branch growth→July-August flowering and fruit setting→October-November harvesting", the flowering period is at the end of July -August. The key to the success of off-season cultivation of four-season honey awn is whether it can bloom on time in July-August. After pruning in April to promote shoots and June to control shoots and promote flowering measures, in some years, due to the influence of many factors such as rain, light, temperature, tree vigor, etc., the secondary shoots may not be able to complete flower bud differentiation o...
