Embodiment 1

[0044] Adopt the method of the present invention to plant long-grain and large-ear corn in the middle ground, plant 3500 plants per mu, return the stalks to the field, apply 45 kg of liquid compound probiotic fertilizer, and simultaneously base 500 kg of vermicompost organic fertilizer, 50 kg of potassium fertilizer, 25 kg of selenium-enriched nutritional vigor, Root irrigation cultivation agent 2kg, plow to 15-20cm underground, then crops can be planted. Before the corn flowering to the filling stage, 5 kg of carbon dioxide long-acting granular fertilizer and 30 kg of liquid compound probiotic fertilizer were topdressed. During the whole growth period, 800 times of phytometabolic regulating factor was used for 50 g twice, and 50 g of phytoimmune regulating factor was used once. The yield per mu is 1416kg, which is 689kg higher than the 727kg of conventional technology, and the yield increase rate reaches 95%.

Embodiment 2

[0046] Adopt the method of the present invention to plant super-big ear wheat, sow 15 kg per mu, return the straw to the field, apply 200 kg of solid compound probiotic fertilizer, and simultaneously apply 450 kg of fulvic acid organic fertilizer, 20 kg of potassium fertilizer, 100 kg of selenium-enriched nutritional vigor, and root irrigation cultivation agent 5kg, plow to 15-20cm underground, then you can plant crops. Before the wheat blossoms to the filling stage, topdress 10kg of long-acting carbon dioxide granular fertilizer and apply it continuously for 15-30d, 100kg of solid compound probiotic fertilizer is topdressed every 10-15d, and 180kg of potassium fertilizer is topdressed every 10-30d. Humic acid organic fertilizer 2550kg topdressing every 10-30d. During the whole growth period, 800-fold solution of plant metabolism regulating factor was used twice, a total of 150 g, and plant immune regulating factor was used once, a total of 250 g. The yield per mu is 981kg, w...

Embodiment 3

[0048] Adopt the method of the present invention to plant hybrid rice, sow 12 kg per mu, return the rice straw to the field, apply 45 kg of solid compound probiotic fertilizer, and simultaneously base 500 kg of vermicompost organic fertilizer, 15 kg of potassium fertilizer, 100 kg of selenium-enriched nutrient vigor, and 5 kg of root irrigation cultivation agent , Plow to 15-20cm underground to plant crops. Before the wheat flowering to the filling stage, topdress 8kg of long-acting carbon dioxide granular fertilizer and apply it continuously for 15-30d, 5kg of solid compound probiotic fertilizer every 10-15d, and 85kg of potassium fertilizer once every 10-30d, earthworm Manure organic fertilizer 1500kg topdressing once every 10-30d. During the whole growth period, 800 times of phytometabolic regulating factor was used twice for a total of 100 g, and for phytoimmune regulating factor for 1 time, a total of 200 g. The yield per mu is 970kg, which is 360kg higher than the 610kg...

Abstract

The invention provides an integrated fertilizing method for cultivating selenium-rich organic crops. The integrated fertilizing method comprises the following steps of on the basis of crops per mu, when the crops need to be fertilized, applying 500 to 3,000kg of carbon organic fertilizer with carbon, wherein the carbon organic fertilizer is wormcast organic fertilizer, fulvic acid organic fertilizer or a mixture of the wormcast organic fertilizer and the fulvic acid organic fertilizer; besides, applying 10 to 75kg of compound liquid probiotic fertilizer or 50 to 300kg of compound solid probiotic fertilizer, 50 to 200kg of potash fertilizer, 25 to 100kg of selenium-rich nutritional vitality element, 5 to 10kg of carbon dioxide long-acting granular fertilizer, 2 to 5kg of root irrigation cultivating agent, 50 to 150g of plant metabolic regulation hormone and 50 to 250g of plant immune regulation hormone. The integrated fertilizing method provided by the embodiment of the invention can realize the effects that grown crops are good in growth vigor and high in yield; the crops are rich in trace elements of selenium and other nutritious elements, so that the crops are more nutritional and are absorbed by human bodies more easily after being eaten.

Description

technical field [0001] The invention relates to the field of crop planting, in particular to an integrated fertilization method for cultivating selenium-enriched organic crops. Background technique [0002] The traditional planting mode has always maintained a natural ecological balance. It is a natural organic agriculture, without chemical fertilizers, chemical pesticides, and environmental pollution. Pure organic fertilizers are used to produce pure organic food. However, the content of nutrient elements in organic fertilizers is too small to meet the needs of crops, so the yield is extremely low. In the traditional planting mode, the reason for the low yield per mu is mainly caused by the low utilization rate of organic fertilizer and the excessive pests and diseases, while the low utilization rate of organic fertilizer and the excessive pests and diseases are mainly caused by too many miscellaneous bacteria in the organic fertilizer and soil, that is, Caused by poor nut...
