Problems solved by technology

The first flower exists in the form of young fruit from the cold December to the next February. It is most susceptible to freezing, most of them freeze to death, and only a few survive. Usually, the fruit is large and of good quality; the growth period of the second flower is shorter than that of the first flower. Medium-sized, high-quality, moderately frozen, these flowers are the main force of white-fleshed loquat commercial fruits; three-flowered flowers have less chance of being frozen, but the fruit development period is short, the fruit is small and poor in quality, and has no commercial value

Embodiment 1

[0017] The white-fleshed loquat variety 'Ruantiaobaisha' has an early flowering period and severe frost damage. In order to delay the flowering period, improve yield and quality, topping should be carried out in mid-March when the spring shoots are 3 to 5 cm long, and fixed buds should be carried out at the end of April and early May, leaving 1 to 2 strong spring shoots for each branch, and spraying Apply 70% thiophanate-methyl 700 times of liquid+0.3% urea+0.3% (weight ratio) potassium dihydrogen phosphate to promote the growth of new shoots; in the first ten days of June, apply fruit fertilizer, and the fertilizer is compound fertilizer (potassium sulfate type compound fertilizer, nitrogen : The weight ratio of phosphorus pentoxide: potassium oxide is 15:15:15) 0.7kg / plant + urea 0.2kg / plant. In July, the summer shoots issued after the spring shoots are topped are thinned, and the main branches and 1 to 2 side branches are kept. To prevent yellow caterpillars and leaf spot ...

Embodiment 2

[0020] The white-fleshed loquat variety 'Ninghaibai' has many head flowers and severe frost damage. In order to delay the flowering period, improve the yield and quality, topping is carried out in late March when the spring shoots are 3 cm long, and the fixed buds are carried out at the end of April and early May, leaving 1 to 2 strong spring shoots on each branch, and spraying 70 % thiophanate-methyl 800 times solution + 0.3% urea + 0.3% potassium dihydrogen phosphate to prevent disease and promote new shoot growth; in early June, apply fruit fertilizer, and the fertilizer is compound fertilizer (potassium sulfate type compound fertilizer, nitrogen: pentoxide The weight ratio of diphosphorus: potassium oxide is 15:15:15) 0.6kg / plant + urea 0.1kg / plant. In July, the summer shoots issued after the spring shoots are topped are thinned, and the main branches and 1 to 2 side branches are kept. To prevent yellow caterpillars and leaf spot from July to September, 80% mancozeb 1000 ...

Abstract

The invention relates to a method for delaying the first flowering time of white-fleshed loquats and improving the yield and quality of loquats. The method mainly includes the steps of topping in spring shoots, management after topping, management in summer shoots, flowering management and the like. The beneficial effects of the present invention are mainly reflected in that: by adopting the method of the present invention, the first flowering time of the white-fleshed loquat can be postponed for more than one month, thereby reducing the amount of first flowers, greatly increasing the amount of second flowers, and greatly improving the yield and quality of the white-fleshed loquat .

Description

(1) Technical field [0001] The invention relates to a method for delaying the first flowering time of white-fleshed loquat and improving the yield and quality of loquat. (2) Background technology [0002] Loquat, also known as Luju, is called loquat because its leaves are very similar to pipa. Loquat is evergreen in all seasons, and the fruit tree has certain ornamental value. Loquat fruit is not only delicious and nutritious, but also has the effects of nourishing the lungs, clearing heat and invigorating the stomach, diuretic and nourishing and strengthening the body. It has a good auxiliary effect on promoting digestion, relieving heat, moistening the lungs and relieving cough, and preventing colds; Rich in iron, magnesium, potassium and other trace elements are essential elements for the human body, and the carotene contained in it ranks third among all fruits, and is deeply loved by consumers. Loquats are divided into white-meat loquats and red-meat loquats according ...
