Embodiment 1

[0029] The experiment was carried out in the pepper test demonstration base (18°1'N, 110°13'E) of the Institute of Spices and Beverages, Chinese Academy of Tropical Agricultural Sciences. The present invention takes clear water as the control (T1), adopts four kinds of exogenous gibberellin concentrations of 20, 40, 60, and 100mg / L (T2-T5) to spray the pepper in the main flowering stage, and spray gibberellin in the main flowering stage in 2019 Each treatment selects 3 plants with basically the same growth (the pepper spikes are all removed before spraying gibberellin), and each plant is used as a repetition. When spraying gibberellin, it is necessary to spray the leaves of pepper in all directions. until the leaves began to drip, and the other management measures were the same for each treatment. When spraying, care should be taken not to contaminate other pepper plants. After one month of treatment, count the number of spikes whose length is fresh, 2cm, 5cm, and 8cm. Measur...

Abstract

The invention relates to the technical field of agricultural cultivation, in particular to an exogenous gibberellin spica increase method of piper nigrum. The method comprises the steps as follows: atthe main flowering stage of the piper nigrum, exogenous gibberellin with the concentration of 20-100 mg / L is sprayed to leaves of the piper nigrum. Tests are conducted according to the gibberellin spica increase method, the exogenous gibberellin spica increase method proves that treatment by exogenous gibberellin with different concentrations has certain influence on growth and heading of the piper nigrum and has great influence on newly headed spica, spraying of the gibberellin can promote heading of the piper nigrum, spraying of gibberellin with concentration of 40-60 mg / L has better effects of increasing leaf morphology parameters such as leaf area and leaf thickness of the piper nigrum, and spraying of gibberellin has unremarkable influence on piper nigrum source leaf photosynthesis,sucrose, starch and sucrose metabolism related enzyme activity. The method lays a scientific foundation for increasing the number of spicas at the main flowering stage and has important significance in optimization of flower regulation and yield increase in piper nigrum production.

Description

technical field [0001] The invention relates to the technical field of agricultural cultivation, in particular to a method for increasing ears of pepper with exogenous gibberellin. Background technique [0002] Pepper (Piper nigrum L.) is a perennial woody vine of the genus Piper in the family Piperaceae. It is known as the "king of spices". play an important role in industrial value. At present, Hainan has become the main base of pepper production in my country, and methods to increase the yield of pepper are constantly being explored, and the number of spikes is a key factor affecting yield. Pepper flower buds are mixed buds, vegetative growth and reproductive growth are carried out at the same time, and can bloom multiple times a year. The main flowering period is from September to November every year. It was found in the research on the regulation of pepper flowering period and the influence of pepper fruit traits on yield that The number of spikes of pepper has the gr...
