1. The experimental method for the delayed cultivation of overwintering red pepper was Chichuan No. 1 (selected for vegetable research of Gansu Academy of Agricultural Sciences), planted on September 6, 2000, and planted on October 30, with a distance of 40cm and a row spacing of 60cm. , Double plant per hole, the plot area is 25.2 square meters, on May 15, 2001, it was postponed after pruning, and it was pulled on September 15, 2001. Another set of normal field management as a control, the area of ​​25.2 square meters.
1.1 Pruning. Cut off all the branches above the four-door bucket, and use paraffin wax to seal the cut-outs. At the same time, clean the dead leaves and rotten leaves of the clean film surface and open ditch.
1.2 post-processing. After pruning, the axillary buds germinate and start to grow. After spraying gibberellic acid for 30 mg?kg (upper right-1) once, during the growth period, 2 to 3 viral treatments are applied to prevent viral diseases, and at the same time, the aphid and white powder are controlled. Oh, to prevent the spread of viral diseases. After mid-June, the front of the plastic film in the greenhouse was rolled up to form a pergola to facilitate the growth of the pepper.
1.3 Clipping management. As a result of pruning stimulation caused by excessive sprouting of axillary buds, excess axillary buds should be promptly removed. When the shoots grow to about 15cm, 4 to 5 new shoots per plant are removed and the rest are cut off. When the new shoot grows to 30cm, it is hauled and hauled. The traction angle depends on the growth of the new shoot. When it grows vigorously, it can relax and bend the growing point of the main branch outwards. As a result, the growing and weak branches can be rewound. To help grow the situation. After mid-July, the formidable shoots of more than 6 cm in the middle and lower parts of the plant were promptly cut.
2.1 Differences in plant traits. There was no significant difference in plant height and plant width between the pruning regeneration treatment and the control at the later stage. The average length of shoots in the treated area was 18.2 cm higher than that of the control, and the ratios of the length of the treated area to the control area were 9:1 and 7 respectively: 1, The drop rate was 10% and 34% respectively. This shows that post-cutting treatment can significantly improve plant growth structure and regulate vegetative growth and reproductive growth balance.
2.2 Investigation of fruit traits. The results showed that there was basically no stiff red fruit in the treatment area. The period of fruit enlargement (days from flowering to commercial fruit formation) was 28 days (days), while the control's rate of stagnant red fruits and fruit enlargement were 12.6% and 33 days (days). The average fruit length and fruit weight of the regenerated plants were 18.7 cm and 29.2 g, respectively, and those of the control were 15.3 cm and 21.7 g. It can be seen that the comprehensive characters of the regenerated plants were better than the control.
2.3 Production and output value calculations. The output (output value) before May 15th, 2001 was taken as the previous output (output value), and the output (output value) from May 15, 2001 to September 15, 2001 was used as the later output (output value). The statistical results showed that Both the previous and control yields were 3539.4 kg/(667 square meters) (upper right-1), and the later yields were 1607.0 and 561.7 kg/(667 square meters) (upper right-1), respectively, and the total processed yield was 25 more than the control. For the treatment and control, the previous production value was 10618.2 yuan (667 square meters) (upper right-1), and the later production value was 5142.4 yuan and 1685.1 yuan (667 square meters) (upper right-1). The total output value of the treatment was higher than that of the control. 28.10% increase, an increase of 3457.3 yuan per 667 square meters.
2.4 Field Incidence Survey. Field disease and virus disease were investigated in the middle of June, July and August in 2001. The field incidences of the treatment and control epidemics were 5% and 26%, respectively, and the field incidence of viral diseases was 18% and 56%, respectively, indicating regeneration. Delayed treatment can significantly improve the plant's permeability and increase the plant's resistance to disease.
Through late-stage pruning of overwintering peppers, the growing period of overwintering peppers was extended from 250 days (days) to 370 days (days). The total output value per 667 square meters reached 1,5760.6 yuan, an increase of 3457.3 yuan over the control, and the economic benefits were significant. Promote it.
