First, the basic characteristics of the variety
The British red variety is precocious, with a growth period of 90-95 days, a plant height of 5-50 cm, a main stem branch of 2-4, a single pod number of 15-20, a red grain of the kidney, a kidney shape, and a grain weight of about 45 grams. The variety has strong adaptability, good disease resistance and high yield, and the general output is 2250 kg/ha.
Second, election
Choose a neutral soil with fertile soil and good soil permeability. Avoid planting in the low-lying stagnant water plots to avoid the stagnation of beans.
Third, soil preparation and fertilization
During the seedling period, the nitrogen fixation ability is weak. On the basis of applying the base fertilizer, a small amount of quick-acting nitrogen fertilizer and ammonium phosphate can be applied as seed fertilizer to promote the growth and development of seedlings. Generally, ammonium sulfate is applied at 75 kg/ha, and diammonium phosphate is 50. Kg/ha can be used. Nitrogen fertilizer should not be applied too much, so as to avoid plant lengthening and prolonging the growth period. When applying the seed fertilizer, it should be determined according to different types of mature varieties. If the short-lived early-maturing bean varieties have been applied with seed fertilizer, they can no longer be topdressed: if the seed fertilizer is not applied, the nitrogen can be applied when the seedling grows to 4 leaves. Phosphorus and potassium compound fertilizer 150-225 kg / ha.
Fourth, sowing
1. Seed treatment: Dry the seeds for 1-2 days before sowing, promote seed ripening and increase germination rate.
2. Density: British red kidney bean heal seedlings 148500-165000 strains.
3, the amount of broadcast: ç§ use amount of 120-150 kg, 8-10 kg per mu
4, sowing date: planting in late May.
5, the broadcast method: (1) single-line precision on-demand ridge; (2) artificial hole sowing, the hole distance 30 cm, 3-4 capsules per hole. You can choose the seeding, intercropping or intercropping mode.
6, sowing depth: after the suppression of the depth of 5-6 cm.
V. Management of middle cultivating
1. Cultivating: After the seedlings are planted, the plough is ploughed before the shovel. Do three shovel and shovel, and the third cultivator will be carried out before the ridge.
2, weeding: artificial shovel combined with tillage mechanical weeding.
3. It is strictly forbidden to use chemical herbicides.
Sixth, pest control
1, disease
(1) Anthracnose, powdery mildew: continuous rainfall in the early stage of the disease or in the pod-forming period (August), when the soil is excessively humid, spray 1:1:240 Bordeaux mixture (copper sulfate: quicklime: water = 1:1:240), Spray once every 5-7 days, even spray 2-3 times.
(2) Bacterial blight (leaf burning disease): Spray 1:1:240 Bordeaux mixture at the beginning of the disease.
2, pests
(3) Red spider: Ai Fuding 4000 times liquid.
(4) Bean pods, aphids: matrine insecticide sprayed on the leaves, once every 7 days, even spray 2 to 3 times. Or spray with 5% Effort 4000 times solution, or spray huaguangmycin 600 times solution.
Seven, harvest threshing
Threshing method: threshing by manual fielding method, to prevent excessive crushing and causing damage of the grain. It is not possible to use a rod-type or spike-type thresher to perform threshing to prevent mechanical damage to the beans. After threshing, avoid sun exposure to avoid discoloration of the seeds.
