Description

Rice plantation without pesticide and fertilizer

One, technical field:

The present invention relates to the kind method for planting of a kind of paddy rice, particularly disclose a kind of rice plantation without pesticide and fertilizer, the paddy rice of planting by the inventive method is a kind of grain of green, and it is of far-reaching significance.

Two, background technology:

As everyone knows, when the peasant in the rural area plants grain in the farmland, all use chemical fertilizer when generally applying fertilizer, all lean on agricultural chemicals except that insect pest, Shou Huo grain does not often reach the sanitary index of regulation thus, leaves remaining harmful substance.This kind of method for planting not only strengthened peasant's planting cost, cause the minimizing of peasant income, and when spraying insecticide because the suction in the respiratory or to the direct contact of agricultural chemicals, cause endangering peasant's health of human body, particularly importantly, because agricultural chemicals is residual, influenced the quality of agricultural product, the health that has endangered more eater.Now society advocates green non-pollution food energetically, does not use agricultural chemicals and chemical fertilizer, because crop nutrition content can not get guaranteeing the infringement with insect pest, is difficult to guarantee the normal growth in crops.

Three, summary of the invention:

The objective of the invention is to disclose a kind of rice plantation without pesticide and fertilizer, use the grain of the inventive method results, not only reduced the cost that the peasant plants ground, and useful health, be pure pollution-free food, greatly improved social benefit and economic benefit.

The present invention is achieved in that a kind of rice plantation without pesticide and fertilizer, it is characterized in that: a) increase to 1.2 meters～1.5 meters at each bulk paddy rice ridge of farmland in flakes, the ridge compacting is smooth, makes ridge water-tight, and paddy field is matrix fertilizer with green manure; B) arrange that near time and local rural area plant protection unit the pest control time combines according to the various insect pests hatching peak phase in per generation behind the rice transplanting, the control of pouring water, flooding time was filled water in 8～10 hours, paddy rice is submerged in the water fully, and flooding time was at 12～15 hours, and the institute's damaged by vermin on the rice straw is all by drowned at this moment, rice fulgorid swims in each piece paddy field leeward angle, take 80 purposes diddle-net that rice fulgorid and dark moth are picked up to annihilate with artificial, treat that insect pest is eliminated after, The faster the better in draining immediately.Described is the rice field of base manure with green manure, mixed seeding broad bean and high protein herbage, as perennial ryegrass, string leaf prairie dock or alfalfa, the green manure gross yield must reach or above 4500 jin/mu, described broad bean and high protein pasture growing phase are that two seasons of Winter-Spring are to the previous moon of rice transplanting, herbage is pulverized behind the rice field and pours water, and makes green manure rot to decompose in soil.

The invention has the beneficial effects as follows: rice cultivation is deducted the expense of the deinsectization of pouring water without agricultural chemicals, and every mu of paddy field of peasant can be saved cost more than 40 yuan; Green manure has replaced chemical fertilizer, can reduce expenses again about 60 yuan for every mu, and so, the peasant saves more than 100 yuan for every mu altogether.Use the inventive method rice cultivation, Financial cost reduces, and output does not reduce, and social benefit improves, and farmers' income increases, and common people also can be able to eat the green non-pollution rice, and are useful to health.The expenditure that the peasant adopts the inventive method to acquire to pour water the water pump of usefulness and builds the farmland ridge is disposable input, and is with small amount, can bear economically, and once drop into, and long-term being benefited is to thing that makes big profits with a small capital of peasant Lai Shuoshi.The simple science of the inventive method, easily learn well and understand that saving of work and time has also improved labour productive forces.

Four, embodiment:

With the south of the lower reaches of the Yangtze River is example, in conjunction with the inventive method, can plant this three bulks situation of deinsectization method that be divided into farmland infrastructure, green manure kind method for planting and not have agricultural chemicals to paddy rice, is described in down respectively.

1, infrastructure:

It is better in flakes that the field piece is regardless of size (thousand mu ten thousand mu), height actual conditions according to rice varieties rice bar, ridge around each bulk paddy field is increased to 1.2～1.5 meters, widely can make bulldozer compacting in the above leveling water-tight, water inlet power and main water channel guaranteed to finish into water in 8～10 hours, and water level reaches and floods till the paddy rice.Drainage ditch can utilize inlet channel, advances draining and can utilize mutually.Other requires all the same with the infrastructure construction of basic grainfield.The paddy field water retention property of this infrastructure is very good, and is just much of that by rainwater at ordinary times except that arid the time need be irrigated, and key is that to increase ridge water-tight.Drop into so not quite, once drop into lifelong being benefited.

2, green manure kind method for planting:

The green manure that utilizes Honda to produce supplies the required fertilizer of a season paddy rice.The first crop tangerine bar herbage of field mixed seeding broad bean and high protein also, as perennial ryegrass, string leaf prairie dock or alfalfa, gross yield must reach or above 4500 jin/mu.These green manure has been arranged, and it is just enough to supply the required fertilizer of a season paddy growth.Conventional broad bean green manure output has only about 2000 jin/mu, paddy growth for a season is not enough, so utilize its growth cycle of the south of the lower reaches of the Yangtze River from mixed seeding in October to November to late April next year, peripheral resident's muck and peripheral fowl poultry kind ight soil and other fertilizer used sufficient in the time about 5 totally months and execute.Under the situation of fertilizer deficiency, be affixed by a small amount of chemical fertilizer.Green manuring can be carried out according to local actual conditions in other areas.

Ploughed in the field of wanting rice cultivation in preceding about 1 month at rice transplanting then, broad bean stalk and herbage pulverized behind the rice field pour water, make green manure rot to decompose in soil, thereby no longer need any chemical fertilizer, because broad bean and high protein herbage are the very high green manure of vegetable protein, decomposition has just become nitrogenous fertilizer in soil through rotting.To just putting in order the field at the beginning of 6 months by the end of May and transplanting.Other areas can be carried out according to local farming season season.Such paddy rice is fit to transplanting rice and rice seedling, the incompatibility Direct-seeding Rice, and wet because Direct-seeding Rice is done in earlier stage, green manure runs off easily.

Use chemical fertilizer, 1 mu of paddy rice needs 80～100 jin of urea altogether, 50～80 jin of composite fertilizers, and total price is at 100～120 yuan.Use green manure then can save about 60 yuan/mu.Therefore, use the inventive method and can save cost, not only improve grain quality, also increased farmers' income.

3, the deinsectization method of no agricultural chemicals:

Arrange that near time and local rural area plant protection unit the pest control time combines according to the various insect pests hatching peak phase in per generation behind the rice transplanting, the control of pouring water, flooding time was filled water in 8～10 hours, paddy rice is submerged in the water fully, and flooding time was at 12～15 hours, and the institute's damaged by vermin on the rice straw is all by drowned at this moment, rice fulgorid swims in each piece paddy field leeward angle, take 80 purposes diddle-net that rice fulgorid and dark moth are picked up to annihilate with artificial, treat that insect pest is eliminated after, The faster the better in draining immediately.This kind water logging method reduces half than the conventional pesticide control rice insect pest method control number of times that uses, but guarantee that the paddy rice cut must carry out once about previous week, see that rice fulgorid and other pest damage situations carry out after the grouting, just not do not need to carry out water logging if rice fulgorid and other insects do not work the mischief.With above water logging control rice insect pest method, paddy rice does not again need to use any agricultural chemicals in the middle of the season.

With water logging control rice insect pest method, whole rice growing season only needs about 4 times, and every mu of its expense is each as long as 3～5 yuan the electricity charge of pouring water are just much of that, and every mu only needs 18～20 yuan altogether.And need make a call to more than 6 times with the routine control rice insect pest method whole rice growing season of spraying insecticide, therefore can save every mu more than 40 yuan than conventional control rice insect pest method with water logging control rice insect pest method.

The inventive method effect is fairly good, and its infrastructure investment acts on greatly less, and once investment is lifelong is benefited. Endanger planthopper Also can thoroughly annihilate insect pest in the serious situation. The inventive method can be saved about 100 yuan/mu of costs, and big Reduce greatly labour intensity, also had the effect of volume increase. The control paddy rice is not subjected to Pests Damage, under equal conditions, and than routine kind Plant and to increase production about 5%～8%. Such method is at China's In Middle And Lower Reaches of Changjiang River and the Three River Plain and water in all parts of the country The place of source abundance can be used. Use the inventive method, can also play flood fighting prevention waterlogging effect.
