Planting time and method of broad bean

Broad bean can be used as both snacks and dishes. It is a kind of popular vegetable. So how did broad beans come out? What is the time and method of planting it?

Planting time of broad bean

Broad beans are planted in spring and autumn. Seeds are sown in the north and northwest from March to April and in the south in October.

2. Planting methods of broad bean

1. Variety selection. Generally speaking, choose full and disease-free seeds. In the areas with fertile soil and high fertilization level, fertilizer-tolerant and lodging-resistant varieties should be selected to give full play to the potential of yield increase; in areas with poor soil and low fertilization level, stable yield varieties with wide adaptability and barren tolerance should be selected.

2. Seed treatment. Broad bean should be treated with seeds before sowing and sun-sowed for 2-3 days before sowing to improve the germination rate.

3. Land preparation. The selected soil will be ploughed and ditched at the same time to open the soil moisture, the ditch and the ditch are connected, the ditch of the poorly drained field should be dug deep, and the soil moisture surface should not be too wide. After breaking the soil from the ditch, sow in the pond, and then cover the seed with fine dung or fine soil to ensure seedling emergence.

4. Reasonable close planting. The fields with good fertility conditions can be sown sparsely, and the fields with poor fertility conditions should be planted closely.

5. Fertilization. Base fertilizer can be applied before sowing, mainly farm manure. In the period of 3-4 leaves of broad bean, urea 2-3kg, calcium 10-20kg and potassium fertilizer 5-10kg per mu were mixed with three kinds of fertilizers and watered on the roots. Flowering and podding period is the peak period of broad bean life fertilizer, nitrogen fertilizer accounts for 80%, phosphorus 90%, potassium 63%. Generally, urea 3-5kg and potassium fertilizer 5kg are used per mu, and water is applied to the roots. In addition, potassium dihydrogen phosphate or molybdenum fertilizer can be used for foliar spraying to increase 100-grain weight.

6. Irrigation and pruning. Broad bean is a crop that needs more water, with few leaves and low temperature at seedling stage, and generally does not irrigate. There must be sufficient water in flower and pod stage, bud stage and seed filling stage, and timely irrigation of flower and pod water, bud appearance and seed filling water is the basis to ensure the normal growth of broad bean. When the main stem leaves grow to 3-4 bolting compound leaves, the top 1-2 bolting leaves of the main stem should be removed in time, and invalid branches and weak branches should be removed after the beginning of spring.

7. Timely weeding and chemical weeding and pest control

Pull out the weeds in time to prevent the loss of nutrients.

8. Prevent diseases and insect pests. Prevent rodent damage, timely control Liriomyza huidobrensis and diseases. Generally, there are 2 times of prevention and control before the beginning of spring and 3 times of comprehensive control of diseases and insect pests after the beginning of spring. The time of medication was in early December, late January and late February of the following year. Broad bean aphids, root rot and leaf spot are the main diseases and insect pests in the period of broad bean growth and development, and timely control can reduce unnecessary losses.

9. Harvest. Broad bean, which is eaten as a vegetable, is selected according to the standard of green, tender, full grain and good taste. If the seed is too early, the seed is small, too young, and the yield is low; if it is too late, the texture is hard and not suitable for table consumption. Better market economic benefit can be achieved by choosing the best picking period.

The cultivation of broad bean is mainly concentrated in spring and autumn, and it mainly needs the support of nitrogen, phosphorus and potassium fertilizer in its growth process. As long as more attention is paid to flowering and podding in the planting process, and good nutrition and water are added, it will certainly produce full broad beans.
