The method of planting is to draw about 10 centimetres of ditches in the middle of the plume with agricultural tools, to pour a light water (unwatered in the rain), to form a semi-dry-humid lid, to find a straight-range demersal plant, to tighten the pressure, to fill the root water, and to dent slightly about 2 centimetres in the mouth of the dry mud。
3. Non-film resistance to drought-resistant planting techniques (note: this method is not used in rainy season, but the soil cover method is available). In the absence of film, this technique is used to combat drought cultivation in order to increase the rate of activity, increase the production of potatoes and improve the quality of starch. Water pouring through the planting ditch. When the base fertilizer is applied, the water from the planting ditch is poured through. The amount of water per 1 metre per 4-5 kg is guaranteed to go completely through the planting ditch. Two or three layers back to the ground. (a) returning to the soil took place on three levels: first level covered with wet soil and required pressure on more than half the length of the seedlings; the second layer of dry, wet mud cover; and the third layer of fine mud cover, which requires a three-to-five centimetre thickness. Upon completion of the return to the soil, a peak level of about 15 centimetres wide was formed, and the pressure was pressed gently, leaving a slight dent of about 1 centimetre in the middle of the surface, and the seedlings were exposed to only 2-3 knots. Upon return, there is no need for root water. This measure eased the entire surface of the surface and avoided the surface sheeting caused by the pre-sowning and the rapid evaporation of the water (note: the method of planting here and the method of covering the soil applies to the method of planting at the first point above)。
Iii. Flow bottom, science。
Three methods of fertilizing the bottom of the potato:
1. Farmer fattening and grasswood ash, calcium perphosphate and potassium sulphate method: 1,500 kg of fat for farmers
150 kg of grass-wood ash, a pack of calcium phosphate, and 25 kg of potassium sulphate
Yeah。
2. Methods of combining farm and fertilizer: 1,500 kg and used
A package of calcium phosphate, 30 kg potassium sulphate。
