Imitative ecological afforestation method for Haloxylon ammodendron in desert area of sandstorm front

The invention discloses an imitative ecological afforestation method for Haloxylon ammodendron in a desert area of a sandstorm front, belonging to the technical field of plant cultivation. Desert land with a soil water content of 2% and above and a saline-alkali degree of less than 2% is selected as afforestation land. Cultivation belts are dug out along the eastwest trend of the afforestation land before the soil defreezing and plantation. In the cultivation belts, heeling-in ditches for heeling in are dug along the eastwest trend. Then direct-seeding forestation, irrigation, pest control, and enclosing management and protection are successively applied. Cultivation belts are dug out before plantation and afforestation, so that low survival rate and growth rate of Haloxylon ammodendron caused by the fact that weeds compete with Haloxylon ammodendron for water and fertilizer are avoided. At the same time, the original ecology is maintained by keeping certain space between every two cultivation belts and damage to local ecological environments can be prevented. Demands for water during plantation of Haloxylon ammodendron are sustained by the construction of reservoirs. Thus, the transplanting survival rate of Haloxylon ammodendron is remarkably increased to 90% and above in comparison with the traditional transplanting survival rate of about 10%.

Disposable special fertilizer for sugar canes and fertilizer applying method

The invention relates to a disposable special fertilizer for sugar canes and a fertilizer applying method, and belongs to the technical field of fertilizer production and application. The special fertilizer comprises the following components as active components in percent by mass: 18-22% of nitrogen, 4-8% of phosphorus pentoxide, 13-18% of potassium oxide, 4-5.5% of urea sulfate, 2-3% of urea formaldehyde, 0.05-0.07% of a nitrification inhibitor, 0.01-0.03% of a urease inhibitor and 0.015-0.035% of a plant growth regulator. The disposable special fertilizer can meet nutrient needs in the whole growth period of the sugar canes, is safe and does not burn roots and seedlings in the earlier stage, does not lose fertilizer efficiency in the later stage, reduces fertilizer waste and increases economic benefits. After the disposable special fertilizer is matched with the fertilizer applying method provided by the invention, the nutrient needs in the whole growth period of the sugar canes can be guaranteed and earthing-up work can be eliminated, so that the labor input is greatly reduced, and more importantly, the labor for applying the fertilizer for many times can be reduced and the conflict between the management need for applying the fertilizer to the sugar canes for many times and the current rural situation can be effectively alleviated.

Compound fertilizer containing low and middle concentration azophoska humic acid

The invention relates to a compound fertilizer containing low and medium concentration nitrogen phosphorus potassium humic acid, relating to the agricultural fertilizer field. The prior agricultural fertilizer has the following disadvantages that (1) when used for a long time, the prior agricultural fertilizer can destroy soil and cause soil hardening; (2) the quality of agricultural products is low, due to the application of chemical fertilizer and pesticide, both taste and quality of agricultural products are decreased significantly and the quality is inferior to that of green products which only adopt farmyard manure; and (3) the prior agricultural fertilizer has single nutrition and causes fertility decline, low utilization rate and higher cost when used for a long time. Through the ammoniation of the humic acid by ammonium carbonate, the compound fertilizer containing low and medium concentration nitrogen phosphorus potassium humic acid is prepared according to the proportion of 8 to 14 portions of nitrogen, 8 to 12 portions of phosphorus, 5 to 8 portions of potassium and 15 to 25 portions of aminated humic acid; moreover, the compound fertilizer has the advantages that the compound fertilizer can improve soil, promote crop growth, reinforce the capabilities of crops for resisting plant diseases and insect pests, lodging and drought and improve the quality of agricultural products.
