Planting techniques of long and precocious lentils in simple harvest period

Lentils, also known as eyebrow beans, Emei beans, planting a wide range, long harvest period, but harvest late, very early lentils varieties can be listed about 100 days in advance. Lentils tender pod protein and calcium, phosphorus, iron and other minerals and vitamins rich in crisp and delicious, comprehensive nutrition.

1. Sowing:

1. Sowing time: lentil seeds germinate poorly below 15℃ and stop germinating below 10℃. 20℃~25℃ is the most suitable temperature for germination. The optimum temperature for growth and reproduction of lentils is 20℃~37℃, and when it is higher than 40℃, the growth becomes worse and the number of flowers drops increases. Guangdong area can be sown all the year round (when the temperature is lower than 15℃, cover the film seedling), after transplanting to harvest about 50 days, can be harvested continuously for 6 months.

2. Sowing method: prepare seedbed soil (nutrient soil) before sowing. Farm manure and vegetable garden soil are mixed and leveled according to the ratio of 4:6. Seedbed must be high ridge sunny. When sowing, keep the bed soil moist, with the bed soil hand pinch close, spread open for the degree. Select seedbeds or nutrient bowls to raise seedlings according to local conditions. When the temperature reaches the germination and growth temperature, it can also be sown directly, with 2~3 seeds per hole. When the seedlings are fixed, one strong seedling is reserved. No matter what kind of seedling is used, the seeds should not be soaked and must be sown dry.

II. Transplanting:

Nursery pot or seedbed seedlings, seedlings in 3 to 4 true leaves, timely transplant. Before transplanting, plough the soil, apply enough base fertilizer, apply decomposed farm manure 3000 kg per mu, add compound fertilizer or cake fertilizer 100 kg, level the soil after deep application, and drill holes for transplanting. For varieties with strong growth potential and branching power, base fertilizer can be appropriately reduced according to the original fertility of soil.

Very early maturing varieties are generally planted about 1000 plants per mu, or transplanted according to the row spacing of 100cm× 60cm, one plant per hole. If you want to improve the early yield, density can be appropriately increased.

III. Field management:

1. Frame erection and topping: When the main vine grows to about 30cm, frame erection and tendril introduction shall be carried out in time. The frame construction method is the same as cowpea. Generally, the "human" frame is adopted, and the frame height is about 2.5m. A few horizontal frames are appropriately added in the middle of the frame to facilitate climbing. When the main vine grows to 0.5~1m, the top of the main vine is removed in time to promote the germination and growth of flower spikes. When the lateral vine grows to about 1m, the lateral vine is picked again.

2. Fertilizer and water management: after transplanting, seedlings should be extracted with diluted decomposed human and livestock excrement and urine in time. Because lentils continue to bloom and bear pods, so after flowering and bearing pods, fertilizer and water supply should be strengthened. It is best to pick a batch and drench fertilizer and water once. When picking, do not hurt the flower ears, because the flower ears can bloom again, pod, that is, open "return flowers." In case of long-term high temperature and drought, drought resistance should be carried out in time, and foliar fertilizer should be sprayed to protect flowers and pods.

IV. Pest control:

The main diseases of hyacinth were anthracnose and downy mildew, which were easily caused by high humidity and low temperature during cultivation. The above diseases could be controlled by 50% thiophane methyl and 75% chlorothalonil WP. The aphids occurred in seedling stage can be controlled with 2.5% dimefon 2000 times solution, and the effect is good. In flowering and full fruit stage, the pod borer is mainly damaged. The mixture of 20% dimefon EC and 20% mefon 3000 times solution can be used to control aphids, or 20% dimefon 3000 times solution and other pesticides for controlling stem borers can be used alternately. Pod moth pest control early, in the beginning of flowering buds are not open when spraying once, later to pay attention to observation, timely spraying.
