Embodiment 1

[0025] Embodiment 1: single cropping rice new cultivation, precise fertilization and comprehensive cultivation method, wherein the new cultivation and the new cultivation are:

[0026] Upland dry planting (rice seed coating direct planting "northern cover film" and comprehensive vegetative body); (rice seed coating: after drying, selecting and soaking the fine varieties of single-season rice, pick up and drain the water, and take advantage of the shell of the rice seed If there is humidity, fully mix the seed-dressing type plant energy-gathering fertilizer with water-retaining agent and bentonite according to the set amount, and then coat it with special equipment for granulation and coating for standby; (calculated) and nutrient soil (according to the content of dry seed and dry-raised furrow surface) are fully mixed. The nutrient soil is self-made: 60% peat soil or humus soil, 20% sandy loam, 20% clay, mixing, crushing, stirring Backup.

[0027] Through the above-mentioned ...

Embodiment 2

[0028] Embodiment 2: single-season rice new cultivation, precision fertilization and comprehensive cultivation method, wherein the precise ratio of precision fertilization and fertilization amount is:

[0029] 1. For rice seed coating, use 10 grams of seed-dressing plant energy-gathering fertilizer, 500 grams of water-retaining agent, and 500 grams of bentonite per kilogram of seeds. Ditch water recuperation: dry planting and dry breeding, flat ditch water is moist, so that the root system of rice can be deeply rooted to improve drought resistance and disease resistance;

[0030] 2. The single-cropping rice cultivation uses the special ecological function BB fertilizer for rice, and the precision fertilization amount for a single cluster is 3.5 grams, all of which are applied at the bottom (one-time precise input of nitrogen, phosphorus, and potassium nutrients during the whole growth period of rice).

[0031] 3. Functional urea 1.5 grams per clump (topdressing 0.5 gram / clump ...

Embodiment 3

[0036] Embodiment 3: new type cultivation and precise fertilization single cropping rice comprehensive cultivation method, wherein comprehensive cultivation method is as follows:

[0037] Combine new cultivation with precise fertilization and soil conditioning (adjust the PH value of the nutrient soil to 4--5 for later use), deep plowing and dry farming (use a tractor to turn the previous paddy field by 40 cm to facilitate deep rooting, and use a rotary tiller Horizontal and vertical rotary tillage each 3 times, after drying and leveling, dry planting and dry cultivation, ditch water recuperation, dry and wet), straw fermentation and returning to the field (spray "straw rotting agent" before (70% of which is used for returning to the field) On rice stalks, promote rapid decay, increase organic matter, preserve soil, fertilizer, and improve soil), north-south running (pull the line in the north-south direction, open ditch and plant on-demand to ensure ventilation and light trans...

Abstract

The invention discloses a cultivation, precise fertilization and comprehensive cultivation method for single cropping rice. By the method, various functions such as cultivation and precise fertilization are synthesized into a whole to realize the high yield of the single cropping rice. By the method, dry cultivation and direct seeding or seedling belt pots are used for transplanting, and then the precise fertilization is performed. The method is integrated with soil regulation, deep tillage and dry farming, straw fermentation and return, south and north rowing, wide row distances and narrow planting distances, isometric balanced close planting of wide and narrow row distances and spraying of plant energy-gathering fertilizers. The method is suitable for realizing high quality and high yield of paddy improved varieties. The method has the functions of soil conservation, fertilizer conservation, cold resistance, drought resistance, lodging resistance and pest and disease resistance; and on the premise of ensuring national food security, the using amount of the chemical fertilizers is reduced, the expense of farmers is reduced, the income of the farmers is increased, national energy sources are saved, environmental protection is realized, and the agricultural sustainable development is promoted.

Description

technical field [0001] The invention relates to crop cultivation and fertilization methods, in particular to a new single-crop rice cultivation, precision fertilization and comprehensive cultivation method. Background technique: [0002] There is no standard single-cropping rice cultivation model in my country's agriculture. Water, dry seedlings and field hydroponics, sparse planting and unreasonable close planting are all bottlenecks that restrict the high yield of single-cropping rice. Especially when single-cropping rice is heading, the functional leaves under the ear receive insufficient light. It is difficult to be full, and more than half a grain will cause a reduction in production; farmers have no standards for cultivated land, and they are blind and random. Most of the paddy fields are not plowed deeply, and they are directly cultivated with a rotary tiller, resulting in a thin layer of mud on the surface of the field (after water purification. compaction), but the su...
