Embodiment Construction

[0026] Hereinafter, the embodiments of the present invention will be described in detail with examples, so as to fully understand and implement the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects.

[0027] The present invention provides a method for planting rice in the desert, including the following steps:

[0028] 1) Selection of varieties: Choose varieties suitable for desert planting, these varieties need to be resistant to strong light and drought. Due to the higher desert temperature and earlier maturity than in general areas, it is better to choose late-maturing japonica rice varieties (Qiuguang, Beilu 128, Tengxi 138, etc.).

[0029] 2) Directly dig out desert soil to raise seedlings in accordance with ordinary field seedling raising methods. The transplanting period is preferably 5-6 leaves to minimize the time in the field.

[0030] 3) Land consolidation:

[0031] 3.1) Laying water barrier:...

Abstract

The invention discloses a method for planting rice in desert. The method includes the following steps of variety selection, rice seedling raising, soil preparation, transplanting, fertilizing, moisture management, disease and pest control and harvesting. According to the method, soil of a desert plough layer is improved through a biomass mixture, and the water retaining performance, the content of nutrients and the buffering capacity of the desert plough layer are improved; degradable polylactic resin films are laid below sandy soil, and meanwhile the ground surface is covered with degradable polylactic resin films, so that evaporation of moisture of desert is reduced, and the use efficiency of moisture is improved.

Description

Technical field [0001] The invention belongs to the field of rice cultivation, and specifically relates to a method for planting rice in the desert. Background technique [0002] At present, there are a large number of deserts around the world, and the rapid increase in population has led to a rapid increase in desertification. It is estimated that by 2030, the world's population will increase by about 40% to over 8 billion, but the arable land area used for food production globally can only increase by 7%. Therefore, how to use and transform the existing large amounts of desertified land is an urgent problem to be solved. [0003] Rice is one of the main food crops in the world, and about one third of the world's population feed on rice as the staple food. Desert areas are well cared for and are high-yield areas of rice. Therefore, the development of rice cultivation in the desert plays an important role in ensuring global food security. However, the desert land is barren and l...
