Planting time and method of chickpea

The planting time of chickpea is from April to May in spring, June in summer and October to November in autumn. Soil preparation and fertilization: apply sufficient base fertilizer after deep ploughing and raking of the soil. Planting density: erect plant type varieties, planting density is about 50 plants per square meter, scattered plant type varieties, planting density is about 33 plants per square meter. Late management: proper ploughing 30-60 days after sowing can effectively inhibit the growth of weeds, spraying herbicides before emergence and reasonable watering and fertilization in the later stage.

First, sowing time

Generally, chickpeas are sown from April to May in spring, June in summer and October to November in autumn. Seeds with good quality and high yield should be selected before sowing.

II. Soil preparation and fertilization

1. It is better to plant chickpeas in fertile sandy loam soil with convenient drainage and irrigation, but not in continuous cropping land and saline-alkali land.

2. After soil preparation, sufficient base fertilizer is applied, autumn sowing can be spread directly in the field, the sowing amount per mu is about 1000 kg, general seed fertilizer is ditched before sowing, and the depth is about 8-10cm. In order to avoid sprouting, the fertilizer should be about 5-8cm away from the seeds, and about 10 kg of superphosphate can be applied per mu.

3, in the early flowering stage of the plant, the root topdressing can be carried out, the depth is about 10-15cm, about 10-15cm away from the plant, about 10-12 kg of urea can be applied per mu, while topdressing can be carried out with trenching and soil cultivation, foliar topdressing can be carried out at the full flowering stage of the plant, 100g of dihydrogen phosphate or 200g of urea can be sprayed on the leaf per mu, and 5g of Shibao can be sprayed.

Third, intermediate seedlings

Chickpea has strong adaptability to different planting densities. For erect plant type varieties, the suitable planting density is about 50 plants per square meter, while for scattered plant type varieties, the suitable planting density is about 33 plants per square meter.

Fourth, ploughing and weeding

1. About 66 days after sowing, chickpeas should be weeded regularly to ensure that there are no weeds in the field, which is beneficial to the rapid growth of seedlings.

2. About 30-60 days after sowing, in order to improve soil permeability, intertillage can be carried out properly, and weed growth can also be controlled. secondly, about 1000-1500 grams of grass is not green or 1000-1500 grams of herbicide per hectare can be sprayed before seedling emergence. Or 1000 grams of legume, and so on, which is not only conducive to weeding, but also increase yield.

Fifth, timely watering

1. In most winter sowing areas, chickpea has more rainfall before sowing and early growth, and the soil moisture is more suitable for plant growth, so it does not need watering.

2. If sowing in spring and sowing in winter in arid areas, the rainfall is relatively small, which can not meet the water demand before sowing and in the early stage of growth, water should be replenished in time, and the water demand is relatively large during the period of 4-6 true leaves and pods. Watering must be carried out in time to ensure high yield.

VI. Fertilization

In general, chickpeas are mainly applied with organic fertilizer and cake fertilizer, and appropriate amount of phosphorus fertilizer is applied according to soil fertility, 1.5-3 kg of phosphorus pentoxide per mu. In order to increase yield, appropriate amount of molybdenum and zinc fertilizer can also be applied.
