(I) Applying base fertilizer
Mungbean rhizobium has nitrogen-fixing ability, but increasing manure and phosphorus and potash have obvious effect on yield increase. Shinongjia fertilizer can be applied once before planting, and the soil can be turned over after planting. If it is too late to apply base fertilizer, in the early stage of growth, that is, branching, beginning flowering period, to apply a certain amount of nitrogen and phosphate fertilizer, in order to enhance the ability of rhizobia to fix nitrogen and increase flower bud differentiation.
(b) sowing
Mung beans can be sowed in spring and summer. Spring sowing in late April to mid-May. Summer sowing in the middle and late June, we must strive to broadcast in the early days. Mungbean seeds have 10% small hard particles, it is difficult to germinate after sowing, it is easy to cause lack of seedlings off the ridge, should be sieved before sowing. Mu seeding volume is generally 1.5? 2 kg, seeding depth of 3? 5 cm is appropriate.
(III) Field Management
1. Seedlings, Dingmiao When the mung bean reaches the two-leaf after emergence, it is necessary to remove the seedlings. 4 leaves when the Dingmiao, plant spacing 13-16 cm, single row spacing of 40 cm, l.125 million seedlings per acre is appropriate.
2. The height of the cultivator's mung bean grows from shallow to deep and then to shallow.
3. Irrigation and drainage of mung bean flowering and sowing period is the peak period of fertilizer and water, if the drought in this period must be watered in time to keep the soil moist. However, the flowering and sowing period is often in the rainy season, making the stems and leaves prolonged, resulting in a large number of falling flowers, falling dead, or the death of water. Drain the water in time to ensure the normal growth of mung bean.
4. The interplanting mung beans have strong shade tolerance, and they are interplanted with high-stalk crops, interplanted or mixed in production. Introduce several forms:
Spring corn interplanting mung bean Spring maize is planted in large and small rows, with 1 meter large rows, 50 cm small rows, 33 centimeters of plant spacing, about 2650 plants per acre, or 1.6 meters large rows, 50 cm rows of small plants, 26 cm plant spacing, per acre. About 3000 strains. After pollination, maize interplanted 3 to 4 rows of precocious mung bean with short growing period, small plant, and concentrated pods. The line-to-line ratio is 2:4, or the line-to-line ratio is 1:1, that is, a single row of spring corn interplants mung beans in a row, and this type of mung bean is too shady, which affects the output.
Mung bean and summer corn were planted in large and small ridges between summer maize, and two rows of precocious mung beans were interplanted between big rows. If wheat is interplanted with corn, then mung beans can be sown immediately after the harvest; if the wheat is harvested after replanting, mung beans can be sown at the same time with corn in the form of 2:2.
Mixed with mung bean and summer sesame, the mung bean and the sesame were mixed at the same time. After harvesting, the sesame was harvested at a time when the mung bean was full of flowers and knots. The light was sufficient, which was favorable for the growth of the mung bean and the fullness of the grain.
Mung bean and millet are intercropping between mung beans and summer grain. After wheat is harvested, seeds are sown in the form of 4:2 or 2:2.
In short, when mung beans are interplanted with corn, millet or sweet potato, the spacing of mung beans is generally adjusted without affecting the density of the main crop. If using green beans to press green manure, the effect of overturning in the flowering period is best. If green peas are planted in wheat ridges, after the wheat is harvested, mung beans become monocropping.
(d) Pest control
The main prevention and control of mung bean, adult eggs spawning on the bean or tender larvae, larvae after hatching beans damage.
Control methods: Before the storage, the beans were extirpated at a high temperature of 50°C; fumigation was performed with 1.5 kg of sodium cyanide per thousand cubic meters for 48 hours; the temperature was above 20°C, the insecticidal efficiency was 100%, and the germination rate was not affected; Storage and hypoxia custody; a small amount of storage can be immersed in boiling water for 20 minutes, remove and dry in the cylinder, can be stored for a long time, and does not affect the germination rate.
Mungbean rhizobium has nitrogen-fixing ability, but increasing manure and phosphorus and potash have obvious effect on yield increase.
