"King of Rice" Black Rice planting technology is explained in detail!

Black rice is a characteristic variety formed by long-term cultivation of rice. it is rich in nutrition and has high medicinal value. it is often used to cook porridge, make nutritious food and make wine in daily life. it enjoys the laudatory name of "black pearl" in the world. The following is a detailed explanation of the planting techniques of black rice, the king of rice!

First, sowing and raising seedlings

Black rice is different from other rice varieties, it is a temperature-sensitive variety, sowing time is more strict for the climate, generally sowing time is in mid-March, so as to prolong its growth period, heading poplar flowers in time before the high temperature comes, otherwise, before the high temperature comes, it may affect the yield and quality. Before sowing, the seeds will be dried and soaked in warm water to improve the germination rate and make the seedlings emerge neatly. Growth and development is good, choose a sandy loam field with leeward and sunny, convenient drainage and irrigation to sow seeds, sowing sparsely when sowing, it is beneficial to cultivate strong seedlings, generally sowing 4-4.5kg per mu of seedling field, sowing 1.5kg in the field.

2. Rational transplanting

Transplanting can be carried out when the seedlings grow to 15cm, and the seedlings should be transplanted in east-west direction, wide rows and narrow plants, large seedlings with soil, and pay attention to the transplanting density. The number of transplanting seedlings per mu should not exceed 300000, so that they no longer tiller, and the row spacing is 10cm × 22cm. This can increase the ventilation and light transmittance between plants, and make reasonable use of soil volunteer, which is conducive to the healthy growth of plants and improve yield and quality.

Third, increase the application of phosphorus and potassium fertilizer

The fertility required for black rice at each stage of growth is different, but in order to increase its yield, timely application of phosphorus and potassium fertilizer is an important measure. Phosphorus fertilizer is mainly based on base fertilizer, and the application of potassium fertilizer can be combined with the first intermediate ploughing and weeding. In the later stage, selective topdressing is carried out with the growth status of the plant, but a small amount of supplementary application should be applied at the booting stage, which should not be applied too much at one time. After heading stage, we can top apply phosphorus and potassium fertilizer by spraying fertilizer on leaves. The phosphorus and potassium fertilizer mixed with water into a low concentration of dissolved oxygen, leaf spraying, the effect is excellent, in addition, we should pay attention to the application of calcium, black rice absorbing excessive calcium will make its rice grains rough and affect the taste, so it is necessary to apply little or no lime.

Fourth, use little or no pesticides as far as possible

Nowadays, rice planting is mainly through pesticides to control diseases and insect pests, but pesticides will leave residual poison in rice, which will do less harm to the human body when the amount of residual poison is small, but the continuous accumulation will also affect human health and reduce the quality of black rice. therefore, when planting black rice, try to use agricultural control-based control measures, whether it is diseases and insect pests, or other problems, to eliminate diseases and insect pests. To solve the problem but without the purpose of pesticide residue, in addition, black rice should be harvested in time, once the harvest is late, it will affect the quality of black rice and affect the taste.
