Juvenile Mulberry Orchard Interplanting Plastic Film Potato Technology
Sowing date
From late January to mid-February.
2. Fertilization and soil preparation
Per-mu ditch process cooked cattle and sheep pigs fertilizer 3000-4000 kg, diammonium phosphate, potassium sulfate 10-15 kilograms each, vegetable-specific fertilizer 50-75 kilograms, and 1.2-1.5 kilograms of ammonium per acre for soil pest control, Then plow the rakes in time to achieve the quality requirements of “land level, soil fineness, fatness, fullness, and insect removalâ€.
3. Selected dried seed potatoes
70-80 kg of "Kexin VI" virus-free seed potato per acre. Before sowing, remove the unqualified potato pieces that appear during storage, such as freezing, injury, and severe wilting. After selection, plant the potatoes and put them under low-light conditions for 10 to 15 days to prodigiously shoot early.
4. Ridge coating
Leave ridges at 50 centimeters from the mulberry leaves. After ridging with nutrients, the ridge height is 25-30 centimeters. The ridge width is 50 centimeters. Use 70% methoxamone wettable powder 50-60 grams or 33% pendimethalin cream per acre. 100 to 150 grams of water, 45 to 60 kilograms, weeding the ridge surface, and then timely film.
5. The large seed potato with a cutting weight of 25g or more should be cut into pieces. Each piece should be guaranteed to have 1~2 buds. The cut surface of the cut potato pieces should be mixed with grass ash.
6. Sowing
On both sides of the 70 cm wide ridge, about 10 cm wide, sowing two lines (three-dimension), by digging holes on the membrane sowing, hole depth of about 15 cm, ridge uphill distance 40 cm, spacing of 28 cm.
7. Field Management
One is to remove buds promptly after budding to ensure that nutrients are supplied to tubers.
The second is to implement topping and control. In the field, when stems and vines appear long, artificial hearts are picked up and chemically controlled. The control method is to use 15% paclobutrazol per acre for 60 kg of water, evenly spray on the stems and leaves, to "control and promote the next."
The third is to combine the growth characteristics of potatoes and the characteristics of required fertilizers. In the case of a good foot and a good sensation, timely spray fertilizer is applied. Potash fertilizer is mainly sprayed with K fertilizer, and potassium sulfate is sprayed once every 8 to 15 days. After flowering, no nitrogen fertilizer is applied. Otherwise, the stems and leaves will be lengthy, hindering the formation of tubers, delaying the development, and easily producing small potatoes and malformed fruits.
The fourth is to pay attention to drought prevention before the emergence of buds before the expansion of tubers, there should be adequate irrigation when there is drought, to promote growth.
8. Earlier harvest
The best harvest period was when 90% of the plants began to wither and the stems and leaves turned yellow.
