Embodiment 1

[0010] The site is Naka village, Goroka District, Eastern Highlands Province, Papua New Guinea, Papua New Guinea, at 6 degrees south latitude and 1450 meters above sea level. The perennial upland rice variety Jinshan 1 was selected , on flat land without ridges and dry land on sloping land, turn the soil and prepare the land under drought conditions, soak the seeds in water for 48 hours, and germinate for 48 hours, sow in holes with a depth of 2.5cm, sow 5 or 6 grains of upland rice in each hole, and cover with soil The soil thickness is 1-2cm, and the normal growth is ensured by rainfall and the root system of upland rice stretching into the deeper soil layer to absorb water. Nitrogen fertilizer and compound fertilizer are applied 10-15 days before harvesting of upland rice to promote tillering and budding of upland rice. For the growth of latent buds, rice heads are left after the upland rice is harvested as the seedlings for the next growth. When the upland rice is harvested...

Abstract

The perennial dry rice cultivating technology is dissimilar to available water rice and dry rice cultivating technology. The dry rice is seeded in dry flat or slope land and its roots stretch deep soil layer for normal growth on rain water. After one harvest, the rice stubble remaining in soil is used for culture seedling of the next crop, and corresponding scientific measures are taken. In the area with proper conditions, once seeding can harvest for over ten crops. The said technology has the advantages of saving in seed and labor, and high yield, and is suitable for application in low altitude areas of tropical zone and subtropical zone.

Description

technical field [0001] The invention relates to a paddy cultivation technique, in particular to a upland rice perennial root cultivation technique. technical background [0002] The main varieties of food are rice, wheat, corn, etc. The production and cultivation methods of rice mainly include paddy rice and upland rice. In places with suitable climate, as long as the water source is sufficient, paddy fields can be used to plant rice. As the global population increases, the demand for rice increases, and most of the arable land suitable for rice cultivation has been planted with rice. Therefore, using upland cultivation of upland rice has become one of the effective ways to expand rice production. [0003] There are mainly two kinds of rice cultivation techniques, one is to sow once and reap once; the other is to sow once and reap twice, which is called ratooning rice cultivation. At present, the technology of rice sowing once perennial and multiple harvesting is still in t...
