Embodiment 1

[0032] 1. Variety selection

[0033] Choose varieties that have a suitable growth period, strong germination potential, lodging resistance, and salt-alkali tolerance. The variety planted in this example: Shengdao 19.

[0034] 2. Soil preparation

[0035] Plow the land before winter, and then rotate it 1-2 times in spring, and level it after watering. Large-scale plots should be separated by building ridges to separate plots with large height differences. The width of the ridges is 50-60cm. After the ridges are divided, the land is required to be leveled, and the height difference of the same plot should not exceed 3cm to ensure uniform moisture in the field. manage.

[0036] 3. Sowing

[0037] 3.1 Germination

[0038] 3.11 First, measure the germination rate and germination potential of the rice seeds, and select the rice species with a germination rate and germination potential above 90%.

Abstract

The invention discloses a mechanical water direct sowing culture method for rice in slight alkaline land in the Yellow River Delta. The method comprises the steps of variety selection, land preparation, sowing, water management, fertilization, weeding and disease and pest control. Before sowing, rice seeds are soaked for accelerating germination till revealing; sowing is conducted when the average temperature is at 12 DEG C or above stably in May; it is required that the soil salinity is below 3%o; a 5-10-cm water layer is built in a field in the sowing process, and the root systems of reeds are fished and removed after irrigation; a mechanical broadcast sower is used for broadcast sowing, and the sowing quantity is 12-13 kg/mu; after sowing and before emergence of seedlings, the 5-10-cm water layer is kept; after emergence of seedlings, water is drained immediately. The method is directed to medium and slight alkaline land; compared with an existing mechanical dry direct sowing culture method for rice, the requirement for salt and alkali is low, time and labor are saved, and meanwhile, the method has a higher yield increase advantage and has great significance in alkaline land improvement, agricultural production efficiency improvement and food crop yield increase.

Description

technical field [0001] The invention relates to a mechanical water direct-seeding cultivation method of rice in mild saline-alkali land in the Yellow River Delta, which belongs to the field of agricultural technology. Background technique [0002] In the saline-alkali area of ​​the Yellow River Delta, there are nearly 8 million mu of unused saline-alkali land and more than 11 million mu of low- and medium-yielding fields that need to be developed and utilized urgently. Rice is a pioneer crop for improving saline-alkali land. By planting rice, developing and utilizing saline-alkali land, fully tapping the potential of increasing yield in low- and medium-yielding fields, and establishing an ecologically efficient rice production technology system, it can effectively promote the sustainable development of agriculture in the saline-alkali area of ​​the Yellow River Delta. [0003] In the saline-alkali area of ​​the Yellow River Delta, there are few people, there is a shortage o...
