Embodiment Construction

[0012] The breeding and cultivation technology of wheat is characterized in that it comprises the following steps.

[0013] 1. Precisely prepare the soil, apply sufficient base fertilizer and rotary tillage twice for sowing. After sowing, it must be suppressed with heavy loads. When sowing, the soil moisture content of the clay soil plow layer should be more than 20%, loam soil more than 18%, and sandy soil more than 16%, accounting for about 70% to 80% of the field water capacity. The amount of fertilizer required for the whole growth period of wheat with a general yield of 7500kg / hm2 is: 210.0kg of pure nitrogen, 90.0kg of phosphorus, and 60.0kg of potassium. On this basis, apply 1,500kg of refined organic fertilizer or 15,000kg of fully decomposed organic fertilizer per hectare; one-time bottom application of phosphorus and potassium fertilizer, and 70% bottom application of nitrogen fertilizer + 30% topdressing at jointing stage.

[0014] 2. Appropriate sowing at the righ...

Abstract

The invention provides a wheat seed selection and cultivation technology, belongs to the field of agriculture, and especially relates to a wheat cultivation technology. The invention provides the wheat seed selection and cultivation technology which improves wheat disease resistance and increases wheat ears. The wheat seed selection and cultivation technology is characterized by comprising the following steps: 1, performing fine land preparation, applying sufficient base fertilizer, performing rotary tillage for two times, sowing, after sowing, pressing with weight; 2, appropriately sowing at proper time, preferably sowing from 25 September to 5 October; 3, performing winter irrigation at proper time, seeding safe wintering protection generally beginning when average temperature is 7 DEG C to 8 DEG C, and ending when average temperature is about 5 DEG C, at the time, night freeze melting in the day and winter irrigation being just in time; 4, watering jointing flowering liquid, to protect spikes and increase grain number, applying a jointing fertilizer again, to effectively improve percentage of earring-tillers and increase ear grain number. The watering jointing flowering liquid is an important measure to improve yield of wheat, and can satisfy requirement of wheat on water in a later stage, and reduces sterile florets and spikelet, increases ear grain number, improves grain weight, and realizes water-saving efficient cultivation.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a wheat cultivation technique. Background technique [0002] Wheat is an annual herb with a height of 30-120cm. Leaf sheaths glabrous; ligule membranous, short; leaves flat, strip-lanceolate, 10-20cm long, 5-10cm wide. Spike cylindrical, erect, 5-10cm long, 1cm wide, 1 spikelet at each node of the cob; spikelets about 10cm long, containing 3-5 oats, flattened on both sides, facing the cob , sessile; glume ovoid, nearly leathery, with ridges in the middle, and apex extending into short pointed or awn; lemma oblate, with no awn or awn at the apex; inner and outer palea nearly equal in length, with 2 ridges . Caryopsis ovoid or oblong, with short hairs on top, longitudinal grooves on abdomen, easy to separate from lemma. The flowering and fruiting period is from July to September. The caryopsis is large, oblong, with hairs on the top, deep longitudinal grooves on the vent...
