Problems solved by technology

At present, my country's nitrogen fertilizer consumption has exceeded one-third of the world's nitrogen fertilizer consumption. A large amount of fertilizer application has reduced the quality of my country's cultivated land. The most notable feature is soil acidification. Soil acidification will accelerate the loss of nutrients and affect crop root development and nutrient absorption. , breeding plant diseases and insect pests, which will further prompt producers to increase the use of fertilizers and pesticides, forming a vicious circle

Embodiment 1

[0026] 1. Seed selection: select a few king alfalfa seeds, and choose Dingyan No. 2 as a protected crop;

[0027] 2. Seed treatment: cleaning and removing impurities to make the germination rate of alfalfa seedlings above 90%, and drying in the sun for 1-2 days to break the dormancy period;

[0028] 3. Sowing site preparation: Before sowing, it is necessary to prepare the ground carefully, remove weeds, plow 25-30cm deep, and there is no obvious rubbish, and the top is pine and the bottom is solid, so as to ensure full contact between the seeds and the soil and increase the emergence rate; apply cow dung compost (decomposer 1.25 %)8000kg / hm 2 .

[0029] 4. Timely sowing: alfalfa in dry farming areas should be sown in late May or early June, but it should be adjusted to local conditions to make the emergence uniform.

[0030] 5. Sowing method: use 3 or 4 rows of precision seeders, adjust the row spacing to 15cm, and arrange the seeds of the planter in the order of forage oats...

Abstract

The invention discloses an alfalfa planting method. The method comprises the following steps of 1, sowing land treatment, wherein alfalfa sowing land is subjected to weed removing and ploughing treatment; 2, organic fertilizer applying, wherein organic fertilizer or biological compost is applied in the treated sowing land; 3, alfalfa seed treatment, wherein alfalfa seeds are cleaned and subjectedto impurity removing and dormancy breaking; 4, interval sowing, wherein sowing adopts the alfalfa and nurse crop interval sowing mode, and nurse crops are crops with the excellent ground breaking capacity. The organic fertilizer is used for replacing existing nitrogenous fertilizer to perform fertilization, an organic carbon source is supplemented, soil physical properties are improved, and the diversity and activity of alfalfa root system soil normolmicrobiota are maintained conveniently; the nurse crops high in ground breaking capacity are planted at intervals while alfalfa is planted, by means of the excellent ground breaking capacity, when seedlings emerge, the nurse crops can drive alfalfa seedlings to break the ground together, and the survival rate of the alfalfa is further improved.

Description

technical field [0001] The invention relates to the technical field of plant planting methods, in particular to a method for planting alfalfa. Background technique [0002] Alfalfa is an excellent perennial leguminous forage. It has long enjoyed the reputation of "the king of forage" for its unique role and function in its long cultivation history. It can not only provide high-quality protein feed for livestock, but also improve soil and fertilize soil through nitrogen fixation. In recent years, with the development of animal husbandry and the redistribution of industries, alfalfa has played an increasingly important role in agriculture and animal husbandry. It is the preferred legume forage in the development of grass animal husbandry. The current alfalfa planting method has the following defects: [0003] 1. Sowing alfalfa in spring is conducive to its rooting, but dryness and strong wind in spring have become the key factors that endanger the survival of alfalfa seedling...
