Non-polluted cultivation management technology

It is also known as the bamboo shoots and the melons. It is a perennial herb of the family. Roots, warm and humid environment. Its tender meat is tender and tender, and it is a fresh vegetable. Its pollution-free cultivation techniques are as follows.

First, select seedlings

Choose plants that are tidy in shape, high in pregnancy rate, thick and strong in yak meat, low in knots, no males and ash, and low tillers. Before the planting, the pier was dug and divided into small diamond piers with a knife, each leaving 3-4 branches.

Second, land preparation and land preparation

Choose soil fertile, deep plough layer, 2,500 kg of decomposed human and animal excrement or 10 kg - 15 kg of urea. First, shallow shallow water, antegrade withdrawal, rehydration on the second day

2. Scientific irrigation. Follow the principle of “before, shallow, medium and shallow”. Planting is called keeping 10 cm of shallow water. At the end of the tillering, the water level gradually deepens to 15 cm. When the temperature exceeds 35 °C, the appropriate deep irrigation, regular water exchange, and the water level deepens to 30 cm. The water layer is 10 cm deep during harvest. After harvesting, the water is 3-5 cm.

3. Interplanting and weeding, plant adjustment. Weeding should be carried out during the period of planting, weeds can be used as green manure, and roots can be removed from the field. During the gestation period, dead leaves and old leaves are stepped into the mud for fertilizer: and time seedlings are kept. A male plant with strong tillering power, tall plants, developed underground stems, and small knots.

4. Pest control. Leaf rust is treated with 15% powder rusting wettable powder 1000 times solution, or 70% mancozeb irritable powder 800 times solution, or 70% thiophanate WP 1000 times solution. Bacterial blight is controlled with 20% leaf green double 10% ulcerate. Insect pests, mites, ash, sputum, 20% triazophos emulsifiable concentrate 600 times solution, or 27% high-kill emulsifiable concentrate 700-1000 times solution, or 80% chlorpyrifos powder 700-800 times solution, the drug should be alternated Use and ensure that any pesticide is banned 10 days before the safe harvest period.

V. Harvesting

When the leaf sheath blasts out the micro-bright white and the heart leaves turn yellow, it is harvested in time. Cut off the base of the knotted plant with a knife and remove the upper leaf to be marketed. After the harvest is completed, the residual leaves and dead leaves are removed in time, and the field is destroyed.
