Embodiment 1

[0021] (1) Sowing: Select early-maturing potato seed potatoes and sow them between March 15 and March 20 every year. After the soil is rotary tilled and leveled, place the seed potatoes on the soil surface with a row spacing of 70 cm and a plant spacing of 30 cm. The sowing time is 10-15 days later than the conventional sowing time, which is conducive to the reproductive growth of early-maturing potatoes.

[0022] (2) Fertilization: After sowing, apply 2000 kg of decomposed organic fertilizer, 15 kg of urea, 25 kg of potassium fertilizer and 5 kg of phosphate fertilizer per mu.

[0023] (3) Straw mulching cultivation: After fertilization, cover the seeds with fine soil, cover the fertilizer, and then evenly cover the straw with a thickness of 10-15cm, and spread it evenly on the straw with other soil to avoid light leakage and wind blowing away the straw.

[0024] (4) Inserting rods: After the potatoes emerge, use a bamboo pole with a diameter of 5cm and a height of 1.5m to in...

Embodiment 2

[0029] (1) Sowing: Select early-maturing potato seed potatoes and sow them between March 15 and March 20 every year. After the soil is rotary tilled and leveled, place the seed potatoes on the soil surface with a row spacing of 60 cm and a plant spacing of 35 cm. The sowing time is 10-15 days later than the conventional sowing time, which is conducive to the reproductive growth of early-maturing potatoes.

[0030] (2) Fertilization: After sowing, apply 2000 kg of decomposed organic fertilizer, 15 kg of urea, 25 kg of potassium fertilizer and 5 kg of phosphate fertilizer per mu.

[0031] (3) Straw mulching cultivation: After fertilization, cover the seeds with fine soil, cover the fertilizer, and then evenly cover the straw with a thickness of 10-15cm, and spread it evenly on the straw with other soil to avoid light leakage and wind blowing away the straw.

[0032] (4) Inserting rods: After the potatoes emerge, use a bamboo pole with a diameter of 5cm and a height of 1.5m to in...

Embodiment 3

[0037] (1) Sowing: Select early-maturing potato seed potatoes and sow them between March 15 and March 20 each year. After the soil is rotary tilled and leveled, place the seed potatoes on the soil surface with a row spacing of 80 cm and a plant spacing of 25 cm. The sowing time is 10-15 days later than the conventional sowing time, which is conducive to the reproductive growth of early-maturing potatoes.

[0038] (2) Fertilization: After sowing, apply 2000 kg of decomposed organic fertilizer, 15 kg of urea, 25 kg of potassium fertilizer and 5 kg of phosphate fertilizer per mu.

[0039] (3) Straw mulching cultivation: After fertilization, cover the seeds with fine soil, cover the fertilizer, and then evenly cover the straw with a thickness of 10-15cm, and spread it evenly on the straw with other soil to avoid light leakage and wind blowing away the straw.

Abstract

The invention discloses an induction method for the blooming and fructification of early-maturing potatoes in a short-day area, which comprises the following steps of: sowing potato seeds from 15th to 20th in March, fertilizing, covering soil, covering straw, and inserting rods after potatoes germinate; with the growth of the potatoes, binding potato seedlings on the rods, so that the potato seedlings are irradiated for 16 to 20 hours every day after the potatoes germinate; after the early-maturing potatoes bud, spraying 80 to 100 grams of nutrient solution per mu for two to three times, and spraying once at intervals of 4 to 6 days; and after the tuberization of the potatoes, turning the straw over at intervals of 2 to 4 days to remove potato blocks, covering the straw again, and harvesting after the potatoes bloom and fructify. Compared with the prior art, by the method, the blooming rate of the early-maturing potatoes in the short-day area is 60 percent, the fructification rate is 30 percent, the preparation of the hybridized combination of early-maturing varieties is more convenient, and the breeding of new varieties of the early-maturing potatoes is promoted.

Description

technical field [0001] The invention relates to a method for breeding early-maturing potatoes, in particular to a method for inducing flowering and fruiting of early-maturing potatoes in short-day areas. Background technique [0002] Early-maturing potatoes have become the first-choice varieties in most potato-growing areas because of their short growth period, which is conducive to making full use of light and heat conditions and soil resources, going to the market early, and seizing the fresh potato market. Breeding of early-maturing potato varieties Usually, early-maturing potato varieties can only be obtained by crossing early-maturing and medium-early-maturing parent varieties. Due to the short growth period of early-maturing varieties, many early-maturing parents cannot complete the process of flowering and fruiting. In addition, potatoes have always been dominated by asexual reproduction, and their sexual reproduction is extremely degraded. Therefore, it is difficult ...
