Description
Technical Field
The invention relates to a method for improving the nutrient utilization efficiency of mango in a flowering phase, and belongs to the technical field of crop cultivation management.
Background
The mango is a plant of genus mango of family Anacardiaceae, has beautiful fruit appearance, sweet pulp and aromatic flavor, is deeply loved by consumers, is a large tropical fruit and has the reputation of "tropical fruit king". With the development of socioeconomic and improvement of logistics systems in China, mango consumption groups are expanded to the national range from traditional tropical and subtropical regions, and consumption requirements are increased year by year. Like other fruits, nutrient and water-fertilizer management during planting is an important factor in determining mango yield, quality and orchard planting benefit. Mango is a plant of the same male and female plants, and has male flowers and amphoteric flowers on the same inflorescence, but only the amphoteric flowers which can be pollinated normally and bear fruits. The method is influenced by genetic characteristics, the mango trees have large flower quantity and large inflorescence, so that the nutrient consumption of trees can be increased in the development process of inflorescences, and the nutrients of trees are insufficient to a certain extent, so that serious physiological fruit drop is caused. For most mango varieties, the upper half part of the inflorescence is mostly male flowers, the amphoteric flowers are mostly distributed at the base of the inflorescence, and if the upper half part of the inflorescence cannot bear fruits according to a conventional management mode, the nutrient consumption of trees is increased. In the mango primary production area of China, although fruit growers pay more attention to the nutrient supply in the mango flowering phase, nutrients are consumed too much in the mango flowering phase, so that nutrition is deficient and a large amount of physiological fruit drop is generated.
Disclosure of Invention
In order to improve the effective utilization rate of nutrients in an orchard, effectively reduce physiological fruit drop caused by excessive nutrient consumption in a flowering phase and guarantee the planting benefit of the orchard, the invention provides the method for improving the nutrient utilization rate of the mango in the flowering phase under the condition of not influencing the yield, so that the consumption of nutrients in a tree body in the inflorescence development process is reduced, the nutrient utilization rate is improved, the physiological fruit drop is obviously reduced, and the final yield is not obviously changed.
The invention is realized by the following technical scheme: a method for improving the utilization efficiency of nutrients in the flowering phase of mangoes comprises the following steps:
1) 15-20 days before inflorescence germination, spraying the mixed solution A with the following mass concentration once on the whole plant: 0.20-0.25% of urea, 0.15-0.20% of monopotassium phosphate, 0.10-0.15% of magnesium sulfate, 0.02-0.03% of ethylene diamine tetraacetic acid zinc sodium salt and 0.03-0.04% of ethylene diamine tetraacetic acid calcium sodium salt;
2) when the total length of the inflorescences is 5-10cm, cutting off the top ends of the inflorescences one by one, only reserving 1/4-1/3 parts of the bases of the inflorescences, and spraying the mixed liquor B with the following mass concentration once on the whole plant within 2 days after cutting off: 500 times of 600 times of Bibianbang universal amino acid-containing water soluble fertilizer, 0.20-0.25 percent of monopotassium phosphate, 0.10-0.12 percent of sodium ferric ethylene diamine tetraacetate and 0.01-0.02 percent of manganese sodium ethylene diamine tetraacetate;
3) after the full-bloom stage, spraying the mixed liquor C with the following mass concentration to the inflorescence for one time: 500-fold 600-time Bibushan brand universal amino acid-containing water-soluble fertilizer, 0.16-0.20% of honey and 0.008-0.01% of gibberellin, and the fertilizer is prevented from being sprayed to leaves when being sprayed;
4) and (5) managing according to a conventional method until the fruits are ripe.
The whole plant spraying in the step 1) refers to spraying to the leaf surfaces and the branches and the trunks to be totally wet.
The whole plant spraying of the step 2) refers to spraying to the leaf surfaces and the branches and the trunks to be totally wet.
The spraying of the step 3) to the inflorescence only means that the spraying is carried out until the inflorescence is totally wet.
The spraying time in the steps 1), 2) and 3) is 9:00-11:00 in the morning or 16:00-18:00 in the afternoon in clear weather.
The invention has the beneficial effects that: compared with the prior art, the method has the following advantages:
1) the mango flower volume is large, the inflorescence volume is large, the nutrition is consumed in the development process, and after the method is adopted, the inflorescence volume is only 1/4-1/3, so that the tree nutrient is saved, and the nutrient utilization efficiency is improved;
2) although the total amount of mango flowers is reduced after the upper half of the inflorescence is cut off, as the number of amphoteric flowers at the base of the mango inflorescence is higher than that at the top of the mango inflorescence, and nutrients are supplemented respectively before the inflorescence is germinated, in the inflorescence development period and in the full bloom period, the fruit setting rate of the mango is obviously improved, the physiological fruit drop is obviously reduced, and the final yield is not obviously changed;
3) after the method is continuously used for two years, the tree grows vigorously, and under the same management and fertilization conditions, the tree growing vigor of the tree using the method is obviously superior to that of the tree without the method.
