Problems solved by technology

Plate seedlings adopt drought management, which requires frequent watering with small amounts of water and multiple waterings. Coupled with the limitation of water sources, it is very difficult to properly control the water in the seedling field. Strong seedlings, at the same time the cost is greatly increased; in addition, it is difficult to control the growth of seedlings by using wet seedlings or water seedlings, and it is easy to cause leggy and weak seedlings, slow greening and tillering after transplanting, and low yield

Embodiment 1

[0078]Prepare the seedling field: choose a plot with flat terrain, good drainage and irrigation, convenient transportation, clean and pollution-free land for the seedling field. Supporting construction of large-scale steel-frame greenhouse preparatory greenhouse. The ratio of seedlings to field is 1:80 (that is, the seedlings raised in 1 mu of seedling field can be transplanted into the field of 80 mu of land). After the seedling field is plowed to 18cm, the rotary tillage is 12cm. Finishing seedling field, level and consistent. In the later stage, the double-row trays are placed, and the width of the seedling bed is set to 130cm, and the width used for seedling tray laying is 120cm. Seedbed length depends on the sowing area. Leave an irrigation and drainage ditch with a width of 20 cm and a depth of 20 cm between every two seedling beds, and dig a 40 cm surrounding ditch around the seedling beds for drainage and irrigation.

Embodiment 2

[0101] Prepare the seedling field: choose a plot with flat terrain, good drainage and irrigation, convenient transportation, clean and pollution-free land for the seedling field. Supporting construction of medium-sized steel-frame greenhouse preparatory greenhouse. The ratio of rice seedlings to Honda is 1:100. After the seedling field is plowed by 20cm, it is rotated by 15cm. Finishing seedling field, level and consistent. Single row of trays, the width of the seedling bed is 70cm, and the width of the seedling tray is 60cm. The length of the seedling bed depends on the sowing area. An irrigation and drainage ditch with a width of 30 cm and a depth of 23 cm is left between the seedling beds, and a 50 cm surrounding ditch is dug around the seedbed for later drainage and irrigation.

[0102] Pastoral soil selection: collect mature dry field soil, pastoral soil preparation amount: every 667m 2 Prepare 100kg of nutritious fine soil in the field, and prepare 35kg of unfertiliz...

Abstract

The invention provides a method for cultivating dry raised seedlings through rice mulch covering machine dishes and belongs to the agricultural technology field. The method includes steps of seedbed construction, seedbed mulching, dish sowing, dish watering, dish arrangement, mulching, compaction and seedling bed management. The method is advantaged in that thick and firm cone-shaped bud tips composed of coleoptiles and incomplete leaves of the rice have strong penetrating power to penetrate the mulch for seedling, in the seedling process, the soil is moderately utilized to press the mulch, the mulch film is not closely attached to the soil, certain pressure or tension can be formed for the mulch, rice bud tips can break through the mulch, growth of weeds and water loss can be further prevented, and high soil moisture conservation, weeding, whole and strong seedlings, water saving, labor saving, cost saving, strong seedling and production increase are achieved.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and mainly relates to a method for raising rice seedlings, in particular to a method for raising dry seedlings by inserting a rice mulching machine into trays. Background technique [0002] Rice is one of the main food crops in my country and plays a pivotal role in national food security and social and economic development. Since the beginning of the 21st century, with climate change and increasing industrial and urban water consumption, the contradiction between limited water resources and agricultural water has become increasingly tense. Drought resistance, water saving, and light and simple cultivation have become the development trend of modern agriculture. At the same time, with the acceleration of land transfer, the degree of mechanization and scale of rice production is getting higher and higher, especially the machine-transplanting technology has become the leading technology for the...
