Planting method of hemp kernel

Hemp seed is pockmarked seed, which is actually the seed of hemp, a mulberry plant. It is of high medicinal value and can be used to moisturize the intestines and relieve defecation, blood deficiency, vomiting and other symptoms after insecticidal delivery. Can be used for soup or porridge, tea consumption, but also can be used in medicine, a wide range of uses. So how to grow hemp kernel? Today, let's learn how to grow it.

1. Land selection and preparation

Hemp kernel is light-loving and resistant to atmospheric drought, but not resistant to soil drought and waterlogging. Then it has higher requirements for the soil selection of the planting land, and it is usually appropriate to choose the land with water storage, good fertilizer conservation, loose soil, large amount of organic matter in the soil, low groundwater level and convenient drainage and irrigation. At the same time, it is not possible to choose continuous sites. Deep ploughing is carried out in autumn, and then irrigation is carried out in winter or spring, and sufficient base fertilizer is sprinkled at the same time, which generally requires at least 6,000 kilograms per mu. After sprinkling base fertilizer, the land is turned over again, and then the ground is raked flat and the border is ready for sowing.

2. Cultivation techniques.

The time of sowing is related to the climate of the planting place. Generally speaking, seeds are sown in Heilongjiang from the middle of April to the end of May, while sowing is carried out in Liaoning in early April, but Shandong can sow two seasons from March to April in spring and June in summer. There are three ways of sowing, namely, sowing, strip sowing and on demand. The best sowing method is strip sowing, generally the row spacing is about 12 or 13 cm, the plant spacing is about 7 or 8 cm, sowing evenly, and then covering the thin soil to cover the seeds, you can wait for emergence.

3. Field management

Field management is the key to planting or hemp kernel. Usually about half a month after emergence, then we need to start interplanting and replenishing seedlings. Pull out the overdense or weak seedlings, and then wait until the seedlings grow to about 18 centimeters, then you need to plant. In the process of inter-seedling, seedling replenishment and planting, we should constantly combine with ploughing and weeding to promote the healthy growth of hemp kernel. The watering of hemp kernel can not be carried out until about one and a half months after emergence, and combined with ammonium sulfate. While waiting for hemp kernel to blossom, we need to apply two hundred jin of ammonium sulfate and calcium phosphate respectively. After the growth of hemp kernel, we need to carry out scientifically according to its water demand and fertilizer demand.

4. Disease and pest control

There are many diseases and insect pests in hemp kernel, such as white star disease, blight, downy mildew, root nematode disease, white feather disease, white silk disease, hemp jumping beetle, longicorn beetle and so on. The most important disease is white spot, which mainly harms the leaves of hemp kernel. First of all, we need to strengthen the management of the field, and then in the early stage of the disease, the leaves will be removed, and then spray Bordeaux solution to control. While beetles and longicorn beetles can be poisoned with carbaryl wettable powder and dichlorvos emulsion, respectively.
