Embodiment 1

[0037] Embodiment 1: total salt content is the method for planting paddy rice in 0.4-0.6% saline-alkali land

[0038] (1) Throw 80kg / mu of fermented ferns and 100kg / mu of phosphogypsum in the saline-alkaline paddy field with soft soil that has been plowed and stirred, plow and stir again, level the paddy field, and inject water until it is higher than the level The soil surface is 5-10 cm, soaked in the field for 7 days.

[0039] (2) Drain the field water, wash it once with running water, sprinkle 20 kg / mu of ammonium chloride, plow and level it again, inject water until it is 3-7 cm above the water surface, and insert rice seedlings.

[0040] (3) Apply 3 kg / mu of phosphorus fertilizer, 3 kg / mu of nitrogen fertilizer, and 3 kg / mu of potassium fertilizer every 20-25 days, respectively, to supplement rice nutrients until the rice matures.

[0041] After the full planting period, the rice was harvested and weighed. The yield of rice planted in this saline-alkali land was 368.3kg...

Abstract

The invention provides a method for planting rice in saline and alkaline land. First, fermented ferns and ardealite are applied into soil to improve the salinity and pH value of the soil, and meanwhile the fermented ferns contain rich organic nutrients needed by growth of the rice, thereby prompting growth of the rice greatly; then, ammonium chloride is applied, and after the rice absorbs NH3+ in the growth process, acid radical ions of the ammonium chloride have the effect of further lowering the pH of the soil. Thus, by means of the planting method, the yield of the rice planted in the saline and alkaline land can be increased by 20-30%, the salinization and alkalinization of the soil are improved, the pH value of the soil is lowered, and the fertility of the soil is improved. Besides, the method is easy to implement, high in routinization, easy to popularize, low in planting cost and capable of reducing disease and pest damage in the growth process of the rice.

Description

Technical field: [0001] The invention belongs to crop cultivation technology in saline-alkali land, in particular to a method for planting rice in saline-alkali land and fertilizing the same. Background technique: [0002] my country is a large country with a population of 1.3 billion, and its per capita land resources are lower than the world average. The serious shortage of land resources, coupled with poor land quality, has been restricting the development of my country's agriculture. my country has a large amount of saline-alkali land, with an area of ​​99.13 million hectares. It is mainly distributed in Northwest China, North China, Northeast West and coastal areas. production potential. Transformation, management and rational development and utilization of these resources are one of the important ways for the sustainable development of China's agriculture, and they are also of great significance to improving the ecological environment and promoting the sustainable dev...
