1, planting time: lentils are generally cultivated in the open field in the summer, usually after mid-January can be planted. 2, selection of seed sowing: lentils according to the color of its pods can be divided into white lentils, green lentils, as well as purple lentils, which green lentils pods flat thin, crispy, purple lentils and white lentils similar to the pods thick meat. 3, field management: lentils drought-tolerant strong, seedling period of water demand is small, the extension of the period of spreading and pods period of more water. More water is needed, generally 1-2 times watering in the spreading period, and 1 time watering every 10 days in the pod period.

A, planting time

1, lentil open field cultivation time is generally in the summer, after mid-January can be carried out.

2, it should be noted that different regions have different climates, so the sowing time is not the same. For example, the planting time of lentils in the Yangtze River Basin is usually around May-July, and the planting time in North China is usually around June.

Second, the selection of seed sowing

1, lentils according to the pod color is mainly divided into white lentils, green lentils and purple lentils, of which green lentils pods are both flat and thin, relatively crisp; purple lentils and white lentils are very similar, pod meat is thicker, after cooking is very soft.

2, sowing can be combined with tilling the soil per acre into the rotted farmyard manure 3000 kg as well as the appropriate amount of fertilizer as a base fertilizer, fertilizer must be mixed evenly with the soil, rake it and then level the ground.

3, lentil planting method is generally live, you can also take the furrow or hole sowing method, plant spacing control in the 35-50cm, row spacing in the 100-130cm, 3-4 seeds per hole, after the emergence of seedlings in each hole to stay 2 seedlings can be.

Third, field management

1, lentil drought tolerance is relatively strong, the seedling period requires less water, stretching and pods need more water, generally stretching period watering 1-2 times, pods can be watered every 10 days.

2, after watering, we must timely plow and weed, combined with fertilizer, which can prevent the fall of flowers and pods or futile, pre-flowering fertilizer should be less thinly applied, and after the flower pods period of fertilizer should be reapplied.

3, plowing must be shallow, in order to prevent injury to the root, fertilizer will be nitrogen, phosphorus and potassium for a reasonable combination, pay attention to the amount of nitrogen fertilizer.

4, lentils can be set up before the vine, or after the vine with a rope to lead the vine on the shelf, the vine must make the stem and vine evenly distributed in the hedge, when the main vine grows to 1.5 meters can be straightened and plucked, to promote the development of more lateral branches and lateral branches to produce vines, early flowering and pods.

Four, pest control

1, lentil disease is relatively small, pests are mainly aphids and pod borers, aphids can be used to prevent and control imidacloprid and amidacloprid, pay attention to the concentration of the use.

2, the pod borer mainly in the larvae to eat the beans, the seriousness of the pods will eat the whole pods empty, can be taken to foliar spraying 20% Permethrin 2,500 times liquid or 50% fenitrothion 1,000 times liquid for prevention and control, weekly change 1 time, so as not to produce drug resistance.
