[0017] 2) During the full flowering period, at 9:00 in the morning in fine weather, spray the whole plant with the following mixture B once: 30 mg / L GA3 (gibberellin) + 1800 mg / L Yefu brand containing amino acid trace elements Water-soluble fertilizer, spray until the leaves, branches and inflorescences are all moist without dripping water;

[0018] 3) In the early stage of fruit expansion, at 9:00 am in fine weather, the whole plant was sprayed once with the following mixture C: 40 mg / L CPPU (N-2-chloro-4-pyridylbenzene-N'-phenyl urea) + 60 mg / L IAA (auxin) + 3200 mg / L urea, spray until the leaves, bra...

Embodiment 2

[0023] 1) Select a 15-year-old "Red Ivory" mango tree. At the early stage of inflorescence development, at 11:00 am in sunny weather, the whole plant is sprayed with the following mixture A: 60 mg / L 6-BA (6-benzylamino Purine) + 2000 mg / L of KH 2 PO 4 (potassium dihydrogen phosphate), spray until the leaves, branches and inflorescences are all moist without dripping;

[0024] 2) During the blooming period, at 11:00 am in fine weather, spray the whole plant with the following mixture B once: 20 mg / L GA3 (gibberellin) + 2400 mg / L Yefu brand containing amino acid trace elements Water-soluble fertilizer, spray until the leaves, branches and inflorescences are all moist without dripping water;

[0025] 3) In the early stage of fruit expansion, at 11:00 am in fine weather, the whole plant was sprayed once with the following mixture C: 30 mg / L CPPU (N-2-chloro-4-pyridylphenyl-N'-phenyl urea) + 80 mg / L IAA (auxin) + 3000 mg / L urea, spray until the leaves, branches and fruits are al...

Embodiment 3

[0030] 1) Select a 15-year-old "Jinhuang" mango tree, and at the early stage of inflorescence development, at 16:00 in the afternoon in fine weather, spray the following mixture A once on the whole plant: 100 mg / L 6-BA (6-benzylamino Purine) + 1600 mg / L of KH 2 PO 4 (potassium dihydrogen phosphate), spray until the leaves, branches and inflorescences are all moist without dripping;

[0031] 2) During the full flowering period, at 16:00 in the afternoon in fine weather, spray the whole plant with the following mixture B: 35 mg / L GA3 (gibberellin) + 1300 mg / L Yefu brand containing amino acid trace elements Water-soluble fertilizer, spray until the leaves, branches and inflorescences are all moist without dripping water;

[0032] 3) In the early stage of fruit expansion, at 16:00 in the afternoon in fine weather, the whole plant was sprayed once with the following mixture C: 50 mg / L CPPU (N-2-chloro-4-pyridylbenzene-N'-phenyl urea) + 70 mg / L IAA (auxin) + 4000 mg / L urea, spray...

Abstract

The invention discloses a method for obtaining big fruit type mango embryo-free fruits. The method comprises the following steps: 1, executing full-plant spraying at an early inflorescence developmentstage, wherein 60-120 mg / L of 6-BA and 1,000-2,000 mg / L of KH2PO4 are sprayed to surfaces of leaves, branches and inflorescences until they are all wet and no water drips; 2, executing full-plant spraying in a full blooming period, wherein 20-40 mg / L of GA3 and 1,200-2,400 mg / L of a water-soluble fertilizer containing amino acids and trace elements are sprayed to the surfaces of leaves, branchesand the inflorescences until they are all wet and no water drips; 3, executing full-plant spraying at an initial stage of fruit enlargement, wherein 30-60 mg / L of CPPU, 40-80 mg / L of IAA and 3,000-4,000 mg / L of urea are sprayed to the surfaces of leaves, the branches and fruits until they are all wet and no water drips; 4, in 10-15 days after spraying in the step 3, 40-80 mg / L of CPPU, 40-80 mg / Lof IAA and 1,200-2,400 mg / L of a water-soluble fertilizer containing amino acids and trace elements are sprayed to the fruits again until the fruit surfaces are completely wet and no water drips; 5,executing management routinely until the fruits ripe. The proportion of embryo-free fruits in ripe fruits reaches 60%-85%.

Description

technical field [0001] The invention relates to a method for obtaining a large-fruited mango without embryo, and belongs to the technical field of fruit tree cultivation. Background technique [0002] Mango originated in tropical and subtropical regions of Southeast Asia and has been cultivated for thousands of years. Restricted by climate and temperature, only more than 100 cities and counties in seven provinces including Guangxi, Yunnan, Hainan, Sichuan, Guangdong, Guizhou, and Fujian can plant mangoes in China. At present, the mango planting area in the country is nearly 4 million mu, and the total output value exceeds billions. With the improvement of cold chain logistics and the rise of e-commerce marketing models, the demand for mango consumption in my country is increasing, and the scope of consumption has expanded from traditional tropical areas to large and medium-sized cities across the country. Especially with the gradual improvement of people's living standards,...
