Cultivation method of peas

Abstract

The invention relates to a cultivation method of peas. The cultivation method is characterized in that ordinary pea flowers are selected as female bodies, and wild pea flowers are selected as male bodies; calyces and pedals of the ordinary pea flowers used as the female bodies and stamina of the wild pea flowers used as the male bodies are removed together during the initial bloom stage; the calyces and the pedals of the wild pea flowers are removed during the full-bloom stage, the stamina of the wild pea flowers are used for performing pollination on pistil stigmas of the ordinary pea flowers twice, and carefully selecting pea fruits bred by the method as the first generation of hybrid pea seeds; then further selecting the ordinary pea flower as the female bodies, using the first generation of the hybrid pea seeds as the male bodies in the same method, and carefully selecting the pea fruits obtained by pollination of the female bodies and the male bodies as the second generation of the hybrid pea seeds; and directly planting the second generation of the hybrid pea seeds, which are carefully selected, pollinating naturally, and carefully selecting the fruits as domesticated pea original seeds for large-area popularization and planting. The hybrid peas have high emergence rate, early maturation period and high yield, and the quality of the hybrid peas is higher than that of the ordinary peas.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a method for planting peas. technical background [0002] Pea (Pisum sativum Linn.), also known as snow pea, green pinto bean, hemp bean, green bean, Huai bean, Liu bean, golden bean, etc. It is a leguminous plant, originating from western Asia, the Mediterranean region, Ethiopia, and western Asia Minor. Because of its strong adaptability, it has a wide geographical distribution in the world. my country has been cultivating peas since the Han Dynasty, and now they are widely distributed all over the country. Pea is a semi-cold-resistant plant. The seeds can germinate slowly at 4°C, but the emergence time is long, the emergence rate is low, and the yield is not high. Throughout the growth period of peas, air humidity and soil humidity are required to be high. In the seedling stage, it can endure a certain dry climate to facilitate the growth and development of roots. ...

Problems solved by technology

Although pea can form root nodules to fix nitrogen in the air in symbiosis with rhizobia, it cannot meet all the needs of its growth and development. The insufficient part is absorbed from the soil by roots, and the nitrogen content of pea itself is high, so the nitrogen, phosphorus, and potassium content The ratio i...
