How to apply fertilizer scientifically to Dutch beans

Dutch bean (scientific name: Pisum sativum var. Saccharatum) belongs to the genus Pea of Leguminosae, annual twining herb, high 90~180cm. The area where Dutch beans were first cultivated was along the Thailand-Myanmar border about 12,000 years ago. Round body is also known as honey bean or honey bean (Sugar snap peas), flat body is called green bean or Dutch bean (Snow pea), there are small cold beans, Huai beans, sesame beans, green beans, remaining beans, golden beans, back beans, wheat peas, wheat beans, Bidou, Ma Lei, national beans, soft pod peas, pod peas, sweet beans, lotus beans, green spots, green peas and other names. It can be used for food. Dutch beans, also known as lotus kernel beans, cut beans, belong to the pea genus of Leguminosae. Mainly edible young pods, native to the Mediterranean coast and western Asia, Dutch beans tender pods crisp fragrance, high nutritional value.

Morphological characteristics of Dutch bean

Plant characteristics: annual twining herbs, high 90~180cm, whole plant green, smooth glabrous, powdered.

Leaf characteristics: leaves with 4-6 leaflets, stipules larger than leaflets, leaflike, heart-shaped, lower margin with fine teeth. Leaflets ovoid, 2-5 cm long and 1-2.5 cm wide, entire; stipules leaflike, ovate, base auriculate surrounding petiole.

The fertilization technology of Dutch beans determines the planting yield of Dutch beans, so mastering scientific fertilization technology is very important for the cultivation of Dutch beans, let's take a look at the scientific fertilization technology of Dutch beans.

1. Cultivate strong seedlings before sowing, fill the earth or paper bags or plastic bowls neatly with water, adjust the hole depth with a wooden stick, the hole depth is 3 to 4 cm, and then sow. Generally heroic earthwork or paper bags and other seedlings save labor and labor, easy to transplant.

Strong seedling standard: different seasons, different stubble times are different due to different seedling temperature, seedling time is also different. Generally, the seedling age is about 30 days, with 4 to 6 true leaves, short stem nodes, no lodging and no disease.

two。 After re-application of base fertilizer, the crops of the previous crop were turned 20 to 24 cm deep after harvest, sunburned or frozen after harvest. After buckling the shed, spread 3000 to 5000 kg of high-quality rotten organic fertilizer every 667m2, mix 30 to 50kg of superphosphate, 50 to 60kg of plant ash, turn 15 to 18cm deep, and rake flat to make timely planting.

3. After planting, the principle of water and fertilizer management is from planting to budding without watering and fertilizing, mainly ploughing and soil cultivation, in order to promote root development and plant robust growth. The third time ploughing and cultivating the soil to the base of the first node, so that the base grows lateral roots again and expands the absorption area. Immediately after showing flower buds, flush 500 to 700 kg of dilute dung or 15 to 20 kg of compound fertilizer with water, and then hoe the surface for the last shallow ploughing to control seedlings and promote pods. The first pod forms a small pod, and the second flower begins to pour water after it has just withered. After that, due to the continuous flowering and podding of Dutch beans and a branching at the base, there is a large amount of fertilizer and water, which should be irrigated once every 10 to 15 days, and it is best to use dilute feces and chemical fertilizers at intervals of 10 to 15 kilograms of urea. Calcium superphosphate 20 to 25 kg or mature human urine feces 1000 kg. Especially in the peak podding period, 50 kg of plant ash or 10 to 20 kg of potassium sulfate are applied every 667 square meters to supplement potassium.
