Embodiment 11000

[0015] Example 1 with 1000m 2 Area of ​​land as an example:

[0016] 1. Drought nursery

[0017] 1) Selection of seedbed land: choose the pastoral land behind the house or the dry field with fertile soil to raise seedlings, and do not raise seedlings in low-lying, saline-alkali land.

[0018] 2) Make a bed: the width of the bed is 1.2-1.8m, the height is 0-5cm, and the length depends on the seedbed. Turn over in autumn or spring, remove rice stubble, dead branches and leaves, every 10m 2 Apply 350-365g of diammonium phosphate, and rake it into pieces to make it level.

[0019] 3) Seed selection and germination

[0020] (1) Seed drying: choose a sunny day with no wind, and dry the rice seeds (XH95-13) for 5-7 days to increase the germination potential.

[0021] (2) Seed selection: Prepare salt water or yellow muddy water, put in a fresh egg, and the concentration of the egg shell is appropriate when the area of ​​the size of a dime is exposed. Put in the rice seeds and st...

Embodiment 2

[0038] The difference from Example 1 is:

[0039] Using pots to raise seedlings

[0040] 1. Seedbed selection Choose the rural land in front of the house or the dry field with fertile soil to raise seedlings. Seedlings cannot be raised in low-lying, saline-alkali land.

[0041] 2. Make a bed: The mother bed for pot seedling cultivation is made into a width of 1.8-2.0m, the length depends on the seedbed, and the height of the bed is 0-5cm. The mother bed soil should be turned over in autumn or spring, and raked and leveled to ensure that the pot pan and the mother bed are closely combined to prevent overhead. every 10m 2 Diammonium phosphate 350-365g was applied to the mother bed to facilitate the nutrient supply in the later stage of the seedlings.

[0042] 3) Seed selection and germination

[0043] (1) Seed drying: choose a sunny day with no wind, and dry the rice seeds (XH95-13) for 5-7 days to increase the germination potential.

[0044] (2) Seed selection: Prepare sal...

Abstract

The invention relates to a rice cultivation method, in particular to a water-saving cultivation method of sand rice, which is suitable for Khorchin southeast. The method specifically comprises: (1) seedbed land selection, seedbed making, seed selection, sprouting, sowing, and cultivation which can be divided into seedling on upland field and seedling on a bowl disk; (2) seedling cultivation land management: carrying out ventilation acclimatization when rice seedling is at the three-leaf stage, irrigating once every 2-3 days after uncovering a film; and (3) rice seedling transplantation, rice seedling bed management, top application, and weed prevention and cure, wherein the rice seedling transplantation is preferably carried out in the last ten days of May, irrigating for 1.5-3 cm in the field surface is proper, immediately irrigating for 6-9 cm after rice seeding transplantation is preferred, and water-saving irrigation is carried out after regrowing until the seedling is mature. The method of the invention can save cost, lower ground water exploitation and improve the income of local farmers, can generate favorable economic and social benefits and has favorable promotional value.

Description

technical field [0001] The invention relates to a rice cultivation method, in particular to a sandy rice water-saving cultivation method suitable for the southeast of Horqin. Background technique [0002] my country is a country seriously short of fresh water resources, and the water shortage situation in the northern region is even more severe. Food security has always been an important part of my country's national security. Rice, one of the main grain crops in my country, accounts for about 40% of the total grain output. As of 2002, my country had a total rice cultivation area of ​​2817.7×10 4 hm 2 , of which 50% of the paddy area lacks water resources, and 33% face water depletion. Therefore, the research and development of water-saving agriculture, especially the water-saving rice cultivation method, not only saves water resources, but also saves energy and reduces environmental pollution, which is of great strategic significance to our country. [0003] The Horqin ...
