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 a method for increasing ears of pepper with exogenous gibberellin. The method comprises the following steps: spraying exogenous gibberellin on leaves of pepper during the main flowering stage of pepper, and the concentration of exogenous gibberellin is 20-100 mg / L. Test according to the method for increasing ears of gibberellin of the present invention, through the method of increasing ears of exogenous gibberellin of the present invention, it has been proved that different concentrations of exogenous gibberellins have certain effects on pepper growth and earing, and have certain effects on pepper growth and heading. Spraying gibberellin can promote pepper heading, application of 40‑60mg / L gibberellin has a better effect on increasing pepper leaf area and leaf thickness and other leaf morphological parameters, spraying gibberellin has a better effect on pepper heading Photosynthesis, sucrose, starch, and enzyme activities related to sucrose metabolism in source leaves were not significantly affected. The invention lays a scientific foundation for increasing the number of spikes in the main flowering stage, and is of great significance for adjusting flowering and increasing yield in optimizing pepper 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...
