In addition, it is not advisable to cut a fraction of the water to reduce nutrient loss。
Form characteristics
Four seasons of bean roots are more developed, but renewable capacity is weak. The seedling roots grow faster than the above-ground segment, with the main roots of the strains reaching 80 cm deep and the side roots reaching 60 to 80 cm wide, with the main absorbent roots spread over the surface 15 to 40 cm。
Teeth vary according to their variety and are green, dark purple and blue purple. Most of the strains are green, and a few are dark purple red. The growth habits of the tubers are of unlimited and limited type. Roasted, half-cranched or short。
The first pair of first-born leaves is a single leaf, with near-heart shape; the third and subsequent leaves are triple-leaved. In the case of leaf 3, the upper lobe, with a broad osteoporosis of 4 to 16 cm and a width of 3 to 11 cm, has a sharp front, a base circle or a broad wedge, both of which are obscurantized along the veins of the leaf and are tilted on the side; the toy leaves are small and the base is alive。
The total curvature, armpits, shorter than leaves, peanuts at the top of the total bouquet, small pellets, longer oggs; bell-shaped, larvae, larvae, 4 with short, soft hair; white, yellow, then light purple red, 1. 5 to 2 cm long. Plumbing from an armpit, butterflies. White, yellow, pale or purple. Subroom one, with multiple embryos. It's typical self-plowing plants。
The scab bar, which expands slightly by 10 to 15 centimetres, is about 1 centimetre wide and has no hair; the bean bean is sewn along both sides of the bean's belly, with a sharp beak at the front end. The shape consists of a wide or narrow flat bar and a long garden stick, or an intermediate shape, straight or bent. Vegetable nuts are 10 to 20 cm long, have a straight or slightly curved shape, have a twilight or flat shape, and have a husk that is covered with fuzzy hair, and are of varying colours such as green, yellow, purple (or stripes) and yellow white to brown when they mature. With the growth of the bean bean, its back and cascading cascading cords have developed, and the number of thick wall tissues of the central and inner fruit skin has gradually increased, reducing the quality of fresh food. It's time for the harvest. Vegetable nuts are used for food; seeds contain oil, medicines, fresh urine and swelling。
Seed spherical or rectangular, white, brown, blue, black, or red, bright, laced, approximately 1. 5 cm long。
Born in a bean bean seat near the abdominal suture. The number of seeds varies depending on the variety of varieties and the livelihood of the herd. It usually consists of 4-8 seeds, renal shapes, colours such as red, white, yellow, black and stripes, and a mass of 0. 25 to 0. 7 kg in thousands. Chromosomes 2n = 22。
Growing habits
The beans are warm and cold. The temperature range of seed sprouts is 20-30°c, less than 10°c or more than 40°c. The seedlings are sensitive to temperature changes, and at short-term temperatures ranging from 2 to 3°c they start to lose green, and at 0°c they become frozen。
Vegetables are short-lived plants, but the response of different varieties to the light cycle can be divided into three categories: light cycle sensitivity, light cycle insensitive, and medium light cycle sensitivity。
The root of the bean is well developed and has more roots on its side and is more resistant to drought and flooding. Seeds sprouts require sufficient moisture, but they are overwatered, the soil lacks oxygen and the seeds are prone to decay. The amount of water held in the field, which is suitable for the long term, is 60 to 70 per cent of the maximum water held, and the requirements for moisture during the flowering period are strict, with the appropriate air humidity ranging from 65 to 80 per cent。
Vegetable beans are most suitable for deep, soft, decomposed soil cultivation. The sandy soil, the soil and the clay in general are all grown and should not be grown in the heavy clay of the good people in the low wetlands. The appropriate ph is 6-7 and is not suitable for acid or alkyl. Vegetable beans absorb more nitrogen, potassium and less phosphorus. And some calcium。
