Embodiment 1

[0054] A method for cultivating fresh glutinous corn, rice, and cowpea in the open field in the coastal area of ​​South China in rotation for three crops a year, comprising the following steps:

[0055] (1) Cropping period arrangement:

[0056] The first batch of fresh waxy corn in winter and spring is sown in early January, harvested in early April of the following year, and stubble is cleared in mid-to-late April;

[0057] The second batch of early rice is cultivated by direct seeding in late April, harvested in late August, and cleared at the end of August and early September;

[0058] The third batch of autumn cowpea is sown live from the end of August to the beginning of September, harvesting begins in mid-October and ends in mid-to-late December;

[0059] (2) Select suitable fine varieties:

[0060] For the first round of fresh waxy corn in winter and spring, we should choose varieties that are early-maturing, high-yielding, cold-resistant, storage-transportable, and d...

Abstract

The invention belongs to the technical field of crop rotation cultivation of vegetables, and particularly relates to a crop rotation three-crop-one-year cultivation method for fresh-eating waxy corn,rice and cowpea in an open field in the coastal region of south China. The crop rotation three-crop-one-year cultivation method for the fresh-eating waxy corn, the rice and the cowpea in the open field in the coastal region of the south China comprises the following steps of (1) performing crop rotation period arrangement; (2) selecting a proper excellent variety; and (3) executing the cultivationmethod. According to the cultivation method, two crops of early-season rice and autumn cowpeas suitable for seasons are planted after winter and spring fresh-eating waxy corn crops, the total outputvalue of every 667m<2> of the three crops is 1.78 thousand yuan, the total input is 0.55 thousand yuan, and the annual pure income is 1.23 thousand yuan. Compared with a local main cultivation mode oftwo crops in one year of the fresh-eating waxy corn and later-season rice, the annual total income of every 667m<2> is 0.63 thousand yuan, the production cost investment of the two crops is about 0.25 thousand yuan, and the annual average pure income is only 0.38 thousand yuan; and according to the cultivation method, the output value per 667m<2> can be increased by 1.15 thousand yuan, the pure income can be increased by 0.85 thousand yuan, and economic benefits are remarkable.

Description

technical field [0001] The invention belongs to the technical field of vegetable wheel cover cultivation, and in particular relates to a method for cultivating fresh glutinous corn, rice, and cowpea in the open field in the coastal areas of South China in rotation for three crops a year. Background technique [0002] In recent years, fresh waxy corn has become one of the main vegetable varieties in the coastal areas of South my country. It is rich in nutrients, rich in crude fiber, carbohydrates, vitamins, iron, phosphorus, calcium and other elements, and has strong cultivation adaptability. In addition, the cattle and sheep breeding industry has developed rapidly in recent years, and silage is in short supply. The silage processed from the by-products of fresh corn, such as stalks and bracts, can solve the feed problem for the development of animal husbandry. Fresh glutinous corn is also the main vegetable variety transported from south to north in Guangdong, Guangxi, and H...
