Problems solved by technology

Due to the late maturity of potatoes, the rice production season is affected. Farmers must choose early-maturing early rice varieties, early-maturing or mid-maturing late rice varieties, and the production of potatoes and double-cropping rice cannot be increased in a balanced manner, resulting in low yields and low economic benefits. The enthusiasm for crop rice has resulted in an increasing area of ​​winter fallow fields in double-cropping rice areas, which not only wastes land and heat and light resources, but also affects national food security

Abstract

The invention discloses a potato-double cropping rice triple cropping and multiple cropping method in a double cropping rice area in the middle reaches of the Changjiang River. Through reasonable matching of potato-early season rice-late rice varieties, a soil tillage technology and a covering method of spring potato cultivation are improved so as to achieve 1500 kg of triple-cropped grains per mu in the rice field. The spring potato cultivation comprises the following steps: (1), selecting improved varieties; (2) rotary tillage and soil preparation; (3) applying enough base fertilizers; (4) timely seeding; (5) rice straw mulching; (6) field management; (7) timely harvesting. The potato-double cropping rice triple cropping and multiple cropping method has the key point that through reasonably matching crop varieties in three seasons, the soil tillage technology and the covering method of the potato cultivation are improved, so that the potato cultivation ecological environmental conditions can be improved. By applying the method, not only can the early maturity of potatoes be prompted, the contradiction of potato-double cropping rice triple cropping and multiple cropping stubble cohesion tension in a double-cropping rice area in the middle reaches of the Changjiang River is effectively solved, and is the yield increase potential of the double-cropping rice field fully exerted, but also the potato quality is improved, the nutritive value of the potatoes is improved, and meanwhile, the economic benefits of peasants are improved.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a comprehensive high-yield technology for triple-cropping and multiple cropping of potatoes and double-cropping rice in the double-cropping rice area in the middle reaches of the Yangtze River, with a grain yield of 1500 kg per mu. Background technique [0002] It is estimated that there are about 323 million mu of winter fallow cultivated land in southern my country, accounting for 46.6% of the cultivated land in the region. Deducting the unusable arable land due to various constraints, the currently usable winter fallow arable land is about 142 million mu. Especially in double-cropping rice areas, the winter slack period of rice fields is as long as 5-6 months. There are two forms of Dongxiantian, one is Bantian Dongxian, and the other is Bantian Dongpao. Long-term winter slack and winter soaking will inevitably lead to the intensification of soil gleizat...
